Von Duprin PS906 – Frequently Asked Questions

1) Does the Von Duprin PS906 put out 12 VDC or 24 VDC?
Both. The PS906 is field selectable, and it holds its full 6A rating at either 12 VDC or 24 VDC. A jumper comes with the unit, so you set the voltage on site rather than ordering a voltage-specific model. Input side accepts universal 120-240 VAC, so no separate step-down transformer is needed.
2) Do I need a distribution board with the PS906, or is it ready to wire devices to as-is?
The PS906 on its own is the base power supply. Distribution is an option you choose: 8 fuse protected outputs, 8 PTC protected outputs, 2 relay board output, 4 relay board with integrated logic, or independently controlled relays, each also available in a version with fire alarm interface. If you want Class 2 rated outputs downstream, that comes from pairing the PS906 with the 900-8P distribution board. Pick None only if you are feeding a single load or distributing elsewhere in the panel.
3) Will the PS906 keep my access control doors working when the building loses power?
Only if you order it with the battery back-up kit, which is a yes/no option on the PS906. The back-up board auto-selects voltage, so it follows whichever output you jumpered the supply for, 12 or 24 VDC, and carries the system through an AC interruption. There is also an AC status monitor with isolated SPDT contacts plus AC input and DC output LEDs so you can see or annunciate that the utility feed has dropped.
4) Can the PS906 drop power to electric locks on a fire alarm signal?
Yes. The PS906 has a fire alarm relay that can be set for switched or un-switched output, so you can either kill power to the connected locks on alarm or leave that circuit live. If you want the fire alarm interface on the distribution side as well, order one of the FA versions of the distribution board, for example 8 fuse protected outputs with FA or 4 relay board integrated logic with FA.
5) Is the PS906 UL294 listed for access control use?
Yes, the entire PS900 Series carries UL294 certification, which is the standard for access control system units, and the PS906 is rated Grade 1 for commercial service. That combination is what a spec writer or an AHJ on a healthcare, school, or government project normally wants to see on the power supply line item.
6) Will the PS906 run motorized latch retraction exit devices, or do I need a different supply?
Motorized latch retraction draws a heavy inrush and is normally powered by a supply built for it. The BEST RPSMLR2 Series is a power supply specifically for motorized latch retraction exit devices, and the BEST ELR150 Series is a power supply control module for electronic access control. The PS906 is a general access control supply rated 6A at field selectable 12 or 24 VDC with an electronic power limiting foldback circuit for AC current overload protection - that foldback behavior is what protects the supply during fault conditions, and it is worth confirming the inrush figure of your MLR device against it before you commit. For the MLR opening itself, the RPSMLR2 is the purpose-built choice.
7) What is the closest equivalent to the Von Duprin PS906 if I need the same 6A at 12 or 24 VDC from another brand?
The BEST PS161-6 is the closest match on output: it is a 6A power supply with 120V input and 12/24V output, the same dual-voltage, same-amperage profile the PS906 delivers with its field selectable 12 VDC or 24 VDC jumper. The main difference is scope of the platform - the PS906 is built around an option board architecture, with distribution board choices ranging from 8 fuse protected outputs to 8 PTC protected outputs, 2 and 4 relay boards, and independently controlled relay versions, each offered with or without fire alarm interface. The BEST PS161-6 is described specifically for delayed egress exit devices. If you are powering delayed egress hardware, the PS161-6 lands on that application directly; if you are distributing power to a mix of access control devices from one enclosure, the PS906 with a distribution board is the configuration to look at.
8) I only need to power one mag lock or one electric strike - is the PS906 more supply than I need?
Most likely yes. The PS906 is a 6A supply built to feed multiple devices through an option board, and its base form with no distribution board is still a 6A chassis. For a single device, smaller dual-voltage supplies cover it: the Securitron AQD1 is a 12/24 VDC 1 amp switching supply, the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 632 Series is the 2 amp version of that same dual-voltage family. The Adams Rite PS-1 is a 1 amp 12/24 VDC regulated supply that includes battery backup. Step up to the SDC 634 Series at 4 amps if you have a few devices but not a full distributed system.
9) What should I use instead of the PS906 if the system runs 24 VDC only and needs more than 6 amps?
Look at the Altronix AL1024ULACMCB. It is a power supply and access power controller with 115VAC 60Hz input at 4.2A, 24VDC at 10A, and 8 PTC outputs in a grey enclosure. That gives you more 24 VDC headroom than the PS906's 6A and arrives with PTC-protected distribution already in the unit, where on the PS906 the 8 PTC protected outputs are a distribution board selection made at order time. The trade is voltage flexibility: the AL1024 is a 24VDC unit, while the PS906 is field selectable between 12 VDC and 24 VDC with an included jumper, so it can be moved to a 12 volt system later. For 12 VDC only at high current, the Securitron AQS1210 is a 12 VDC 10 amp switching supply.
10) I need battery backup on the supply - which options actually include it?
The PS906 is ordered with a battery backup kit as a yes or no selection, and its battery backup board auto-selects voltage so the transition to backup power follows whichever output you set. Among the alternatives, the Adams Rite PS-1 is a 1 amp 12/24 VDC regulated supply with battery backup, the Command Access PS204/204B is a 2A at 24VDC linear supply with battery backup, and the Detex 10-800 Series includes a 120VAC/24VDC supply with battery backup. The Securitron BPSS is a boxed solar power supply, which is a different answer to the same problem where no reliable AC feed exists.
11) My spec calls for a UL294 access control power supply - does the PS906 meet it, and what else would?
Yes. The full PS900 Series line carries UL294 certification for access control system units, and the PS906 is rated Grade 1 for commercial use, with Class 2 rated outputs available when paired with the 900-8P distribution board. If your submittal only requires a UL listed supply rather than UL294 specifically, the Aiphone AC-PS1250 is a UL listed 12V DC 5A supply for AC Series access control kits, and the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC output and boost circuitry. Check the listing standard your specifier wrote, since UL 6E and UL294 are not interchangeable callouts.
12) Is 6 amps enough, or should I look at a bigger access control power supply?
6A at 12 or 24 VDC covers a substantial bank of maglocks, strikes, or electrified exit device trim. If you need more headroom at 24 VDC, the Altronix AL1024ULACMCB is listed at 24VDC 10A with 8 PTC outputs. For a straight 12 VDC high-current job, the Securitron AQS1210 is 12 VDC 10A. If the load is a single opening or a small system, a 1 to 2 amp unit like the SDC 632 (2 amp, dual voltage) or Securitron AQD1 (12/24 VDC, 1 amp) is the more sensible size.
13) Can I keep maintenance staff out of the PS906 enclosure?
Order the PS906 with the key lock cover option if you need the cabinet secured. Every PS906 has a hinged cover with a lock down screw and a high voltage protective cover over the line side; the key lock cover adds keyed restriction on top of that, which is what most schools and healthcare facilities want where the panel sits in an accessible corridor or closet.
14) What protects the connected devices if something shorts downstream of the PS906?
Two layers. The supply itself uses an electronic power limiting foldback circuit for AC current overload protection, so a fault pulls the output back instead of damaging the unit. Per-output protection depends on the distribution board you specify: choose the 8 fuse protected outputs board or the 8 PTC protected outputs board, with PTC being self-resetting so nobody has to visit the panel with a replacement fuse.
15) What is the difference between the relay board options and the 8 output boards on the PS906?
The 8 fuse and 8 PTC boards simply split the 6A supply into eight protected feeds, all live together, for powering strikes or maglocks. The relay boards switch power instead of just dividing it: 2 relay board output for a couple of controlled circuits, independently controlled relays where each door needs its own trigger, and the 4 relay board with integrated logic where you want sequencing or interlock behavior handled in the panel rather than at the access control head end. Each of those is also offered with fire alarm interface.
16) Which of these are power supplies with logic or relay control built in, versus just DC power?
Several in this group do more than convert AC to DC. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup. The SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection. The RCI DKPS-2A is a power supply with 8 outputs at 12/24VDC and 2A. On the PS906, control is added by the distribution board you choose - 2 relay board output, 4 relay board with integrated logic, or independently controlled relays, each available with or without fire alarm interface, and the PS906's own fire alarm relay can be set for switched or unswitched output. So the PS906 covers logic and relay control through board selection rather than a fixed feature set.
17) Which of these look like alternatives to the PS906 but are not actually enclosure-mounted system power supplies?
A few. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V in a tamper resistant plastic white finish - it moves power through the door edge, it does not generate it, and it would sit downstream of a supply like the PS906. The Command Access CAT Field Tester is a portable 12-24VDC tester that runs off DeWalt, Makita and Milwaukee batteries, meant for bench and field checks rather than permanent installation. The ROFU 9126T is a plug in mini power supply, 12 VDC at 1.5A with time delay, which is a plug-in unit rather than a hardwired enclosure. The PS906 is a hardwired commercial unit taking universal 120-240 VAC input, with a hinged cover and lock down screw and an optional key lock cover.
18) What is the difference between a switching supply like the Securitron AQL4 and the PS906?
The Securitron AQL4 is a switching power supply rated 12/24VDC at 4/3 Amp, meaning its current rating changes with the voltage you select. The PS906 holds a constant 6A output rating at both 12 VDC and 24 VDC, so your available current does not drop when you move the field selectable jumper. Also in the switching family is the Securitron AQD1 at 12/24 VDC 1 Amp. On the linear side, the Command Access PS1 Series is a 24VDC linear supply with 1 amp output. Sizing decision comes down to the total load at the voltage you will actually run.
19) I am standardizing power supplies across a campus - does the PS906 or one of the alternatives simplify stocking?
The PS906 is designed around standardizing on one chassis: a single 6A base that is field selectable to 12 or 24 VDC, with the differences pushed into option boards that mount flat with polarized connectors and no racks or side connectors needed, so the same base covers openings that need 8 fuse protected outputs, 8 PTC protected outputs, relay control, or nothing but power. Battery backup kit and key lock cover are separate yes or no selections on top of that. Among the alternatives, the SDC dual voltage family gives a similar approach across amperages with the 620 Series at 1 amp, the 632 Series at 2 amp and the 634 Series at 4 amp, all regulated and filtered with dual voltage selection - useful if your loads vary widely enough that one 6A chassis everywhere is oversized.
20) Do PS900 option boards need a rack or backplane to mount?
No rack and no side connectors. Option boards on the PS900 platform use polarized connectors and mount flat in the cabinet, which also leaves the terminal blocks out in the open when you are landing wires for electrified devices. That is a real time saver on a retrofit where you are adding a relay or fire alarm board to an existing PS906 in the field.
21) Will the PS906 run on 230 VAC in an overseas or industrial installation?
Yes. The universal input accepts 120-240 VAC, so the same PS906 works on a standard 120 V branch circuit or a 208-240 V feed without an additional transformer or adapter. By comparison the ROFU 9102 is specified at 10/120VAC 60Hz input, so it is a 120 V only unit.
