Securitron PSP Small Filtered DC Plug-In Power Supply

Check the current draw first. The PSP-12 puts out 12VDC at 700mA maximum, so any single 12V device drawing under that is fine, and it is filtered DC, which is what electromagnetic locks and DC strikes need. The PSP-24 covers 24VDC devices at 350mA max. If your device draws more than that, or you are powering several openings off one supply, you need a panel-type supply rather than a plug-in unit. The 16 ft output cable is included, so the outlet needs to be within that run of the device unless you extend the wire.

Output voltage and available current. PSP-12 is 12VDC at 700mA max; PSP-24 is 24VDC at 350mA max. There is no field-selectable voltage on either one, so you pick the model to match the device you are powering. Both are filtered DC plug-in units with an internal thermal fuse and the same 16 ft output cable.

A plug-in supply like the PSP works when there is a receptacle near the opening and you are feeding one low-draw DC device. It drops into an outlet, includes a 16 ft cable, and needs no enclosure or conduit. What it will not do is feed multiple outputs, ride through a power loss, or supply amps. For that, ZenSupply carries panel supplies such as the Von Duprin PS902, 2A at 12/24VDC and field selectable, the SDC 632 Series at 2 amps with dual voltage selection, or the Altronix AL1024ULACMCB with eight PTC outputs at 24VDC 10A. If you need battery backup, look at the Adams Rite PS-1 or the Command Access PS204/204B.

The PSP models deliver 12VDC at 700mA and 24VDC at 350mA, which is sized for small DC devices fed from an outlet, not for the inrush of a motorized latch. Motor latch retraction devices are fed by supplies built for that duty, such as the BEST RPSMLR2 Series power supply for motorized latch retraction exit devices. For delayed egress exit devices, the BEST PS161-6 takes 120V input and provides 12/24V output at 6A capacity.

The Securitron PSP is a plug-in unit with an internal thermal fuse and a 16 ft output cable, drawing its power from a wall outlet. For a supply that carries the load when the outlet does not, the Adams Rite PS-1 is a regulated power supply rated 1 amp at 12/24 volts DC with battery backup, and the Command Access PS204/204B is a linear power supply with 2A at 24VDC and battery backup. The Detex 10-800 Series pairs a 120VAC/24VDC power supply and battery backup with a universal logic controller.

The PSP-24 model is rated 24 volts at 350mA maximum, which suits small continuous-draw DC devices. For heavier 24VDC loads, the Command Access PS1 Series is a 24VDC linear power supply with 1 amp output, the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, and the SDC 632 Series is a 2 amp regulated and filtered low voltage supply. For large multi-device runs, the Altronix AL1024ULACMCB provides 24VDC at 10A across 8 PTC outputs from a 115VAC 60Hz input.

No. The PSP is ordered as a specific output: PSP-12 supplies 12VDC at 700mA and PSP-24 supplies 24VDC at 350mA, so the voltage is fixed by the part number chosen. Supplies that let the voltage be set in the field include the Von Duprin PS902 base power supply, 2A at 12/24 VDC field selectable, and the SDC 620, 631, 632 and 634 Series, all of which are regulated and filtered with dual voltage selection at 1, 1.5, 2 and 4 amps respectively.

The PSP is a single plug-in supply with one 16 ft output cable, so each device it feeds needs its own unit and its own receptacle. To run several openings from one location, the RCI DKPS-2A provides 8 outputs at 12/24VDC and 2A for access control systems, and the Altronix AL1024ULACMCB combines a power supply and access power controller with 8 PTC outputs at 24VDC and 10A in a grey enclosure.

Two comparable items are easy to confuse with a small DC supply. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish - it carries power through the door edge rather than generating it. The Command Access CAT Field Tester is a portable 12-24VDC unit compatible with DeWalt, Makita and Milwaukee batteries, intended for bench and field testing rather than permanent installation. The Securitron PSP is a filtered DC supply that plugs into an outlet and feeds a device continuously through its 16 ft cable.

Yes, the PSP plug-in supply is UL Listed. It is a commercial-rated unit, which is what most access control specs on institutional and multi-family work call for.

No extra protection is needed. The PSP has an internal thermal fuse, so a short or overload on the output shuts it down without an inline fuse block or a PTC module in the run.

A 16 ft (4.8m) output cable ships with the unit, so for a device within that distance of the receptacle there is nothing else to buy. Longer runs mean splicing to your own low-voltage cable, and on 12V especially, watch conductor gauge over distance so voltage drop does not starve the lock.

Filtered DC matters for access control. Unfiltered or poorly regulated adapters leave ripple that makes maglocks buzz, shortens coil life, and can upset card readers and controllers sharing the circuit. The PSP is a filtered DC unit built for this equipment. Comparable filtered supplies ZenSupply carries include the SDC 620 Series, 1 amp regulated and filtered with dual voltage selection, and the SDC 631 Series at 1.5 amps.

The ROFU 9126T is the closest plug-in alternative, a mini plug-in supply at 12VDC and 1.5A with a built-in time delay. It roughly doubles the current of the PSP-12 and adds timing, which is useful on a push-to-exit or REX circuit where you want the lock to stay released for a set interval.

Yes, the Securitron PSP is UL Listed. Among comparable supplies, 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 power supply with 1.5A at 24VDC output and boost circuitry. The Von Duprin PS902 base power supply is a Grade 1 product.

The Securitron PSP takes its power from a receptacle and delivers filtered DC through a 16 ft output cable, at 12VDC 700mA or 24VDC 350mA depending on model. A hardwired alternative fed from line voltage is the ROFU 9102-12D UL/9102-24D power supply, which takes 10/120VAC 60Hz input. The Locknetics LP Series is supplied with an enclosure for panel or closet mounting.

The Securitron PSP supplies filtered DC power with an internal thermal fuse; switching and timing are handled elsewhere in the system. If the opening needs control logic at the supply, the BEST ELR150 Series is a power supply control module for electronic access control, and the Detex 10-800 Series combines a universal logic controller with a 120VAC/24VDC power supply and battery backup. For a plug-in unit with timing built in, the ROFU 9126T is a 12 VDC / 1.5A mini power supply with time delay.

The PSP body measures 2-1/2 inches by 1-1/16 inches, so it is a slim plug-in that sits close to the wall plate rather than a bulky brick. On a standard duplex receptacle it leaves the adjacent outlet usable in most cases.
