Altronix AL400UL – Frequently Asked Questions

1) Can the Altronix AL400UL run 12VDC and 24VDC devices at the same time?
No. The AL400UL is a single-output supply, and you select either 12VDC at 4A or 24VDC at 3A, not both. If you have a mix of 12V and 24V devices on one job, you need two supplies or a multi-voltage/multi-output unit such as the RCI DKPS-2A, which provides 8 outputs at 12/24VDC and 2A.
2) How much current does the AL400UL give me for maglocks or strikes?
4A at 12VDC, or 3A if you switch it to 24VDC. That headroom covers several strikes or a couple of maglocks on one supply. If your load is under an amp or two, a smaller unit like the Securitron AQD1 (12/24VDC 1A) or the Von Duprin PS902 (2A, 12/24VDC field selectable) is sized closer to the job.
3) Does the AL400UL come with a transformer and enclosure, or do I order those separately?
The plug-in transformer comes with it, and the board ships in a grey enclosure. Also included are the charger circuit and the single Class 2 output. What is not included is the standby battery, so add sealed lead-acid batteries if you need backup.
4) Is the AL400UL output power-limited for fire alarm and low-voltage wiring?
Yes. The output is Class 2 rated and power-limited, which is what lets you run it in power-limited raceway alongside fire alarm and CCTV wiring. Altronix lists it for general use, CCTV, fire alarm and PoIP applications.
5) Can I use the AL400UL to run a motorized latch retraction exit device?
Motorized latch retraction devices draw a high inrush and are normally matched to a supply built for that duty rather than a general purpose 12/24VDC supply. The BEST RPSMLR2 Series is a power supply specifically for motorized latch retraction exit devices, and the BEST PS161-6 is intended for delayed egress exit devices. The AL400UL is a general 12VDC 4A or 24VDC 3A Class 2 supply described for uses including CCTV, fire alarm and POIP - confirm the device manufacturer's power requirement before applying it to MLR hardware.
6) What is the closest equivalent to the Altronix AL400UL from another manufacturer?
The Securitron AQL4 is the closest match in output: it is a switching power supply rated 12/24VDC at 4/3 Amp, the same 12VDC at 4A or 24VDC at 3A pairing the AL400UL delivers from a 115VAC 60Hz input. The AL400UL is a power supply/charger that ships with an enclosure and a single Class 2 rated power-limited output, so if battery charging on board matters to the design, confirm that against the AQL4 before swapping. For a linear alternative at the same 4 amp class, the SDC 634 Series is a 4 Amp regulated and filtered low voltage power supply with dual voltage selection.
7) I only need to power one or two strikes - is there something smaller than the AL400UL?
Yes. The AL400UL is sized at 4A on 12VDC or 3A on 24VDC, which is more capacity than a single strike or maglock needs. For lighter loads, the SDC 620 Series is a 1 Amp regulated and filtered low voltage supply with dual voltage selection, the Securitron AQD1 is a 12/24 VDC 1 Amp switching supply, and the Command Access PS1 Series is a 24VDC linear supply with 1 Amp output. The ROFU 9126T is a plug-in mini supply at 12VDC/1.5A with a built-in time delay if the opening needs timed release.
8) I need more than 4 amps or a higher amperage 12V supply - what should I use instead of the AL400UL?
The AL400UL tops out at 4A on 12VDC and 3A on 24VDC. Where the load exceeds that, the Securitron AQS1210 is a switching supply rated 12 VDC at 10 Amp, and the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity intended for delayed egress exit devices. Total the holding and inrush current of every device on the run before choosing between them.
9) The AL400UL has a single output - what do I use if I need to feed several doors from one cabinet?
The AL400UL provides a single Class 2 rated power-limited output, so branching it to multiple openings means adding distribution downstream. If you want the outputs built in, the RCI DKPS-2A is a power supply with 8 outputs at 12/24VDC and 2A for access control systems. Note the lower 2A total compared with the AL400UL's 4A at 12VDC, so size the door count against that ceiling.
10) My spec sheet calls for a Von Duprin power supply - how does the PS902 compare to the AL400UL?
The Von Duprin PS902 is a base power supply rated 2A, field selectable 12/24 VDC, for access control, and it carries a Grade 1 designation. The AL400UL converts 115VAC/60Hz to a single 12VDC at 4A or 24VDC at 3A Class 2 power-limited output and comes as a charger in a grey enclosure. The main difference for an access control job is capacity and architecture: the PS902 is a base unit designed to take Von Duprin option boards, while the AL400UL is a standalone single-output supply at higher amperage. If the drawing calls out PS902 specifically because of those option boards, the AL400UL will not accept them.
11) What input power does the AL400UL need at the wall?
It runs off standard 115VAC 60Hz line power, drawing up to 3.5A, so a normal 120V circuit is all you need. No 208/240V provisioning.
12) Does the AL400UL charge backup batteries, or is it just a power supply?
It is a power supply and charger in one, so it maintains standby batteries in the enclosure rather than needing a separate charging board. Other battery-backed options we carry include the Adams Rite PS-1 (1A, 12/24VDC with battery backup) and the Command Access PS204/204B (2A at 24VDC with battery backup) for smaller loads.
13) What is the closest 4-amp alternative to the Altronix AL400UL?
Two we stock line up closely on output: the Securitron AQL4 is a switching supply rated 12/24VDC at 4/3A, the same output split, and the SDC 634 Series is a 4 amp regulated and filtered supply with dual voltage selection. Step up to the BEST PS161-6 if you need 6A at 12/24V from a 120V input.
14) Which of these is not actually a power supply substitute for the AL400UL?
A few nearby items look like alternatives but do a different job. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V - it carries power through the door edge rather than generating it, so it works alongside a supply, not in place of one. The BEST ELR150 Series is a power supply control module, meaning it switches and controls power rather than converting 115VAC on its own. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs off DeWalt, Makita and Milwaukee batteries for bench and field testing, not permanent installation. The AL400UL is the fixed AC-to-DC supply and charger in a grey enclosure with a plug-in transformer.
15) I need battery backup with the power supply - which alternatives include it?
The AL400UL is a power supply/charger, so charging duty is part of the unit along with its enclosure and single Class 2 output. Peers that state backup explicitly include the Adams Rite PS-1, a regulated 1 Amp 12/24 volt DC supply with battery backup, the Command Access PS204/204B linear supply at 2A/24VDC with battery backup, and the Detex 10-800 Series universal logic controller with a 120VAC/24VDC supply and battery backup. Batteries themselves are generally ordered separately in all cases.
16) Is there a mid-range option between the 1 amp supplies and the 4 amp AL400UL?
Yes, several sit in between. The SDC 631 Series is a 1.5 Amp regulated and filtered DC power controller with dual voltage selection, the SDC 632 Series is a 2 Amp regulated and filtered supply with dual voltage selection, and the Command Access PS210 is a UL 6E/CSA linear supply at 1.5A at 24VDC with boost circuitry. The AL400UL sits above all three at 12VDC 4A or 24VDC 3A.
17) I am powering a 12V access control kit and an intercom - is the AL400UL or the Aiphone AC-PS1250 the right choice?
The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply built for Aiphone AC Series access control kits, so if the job is an AC Series kit it is the matched component. The Altronix AL400UL is a general purpose commercial supply converting 115VAC/60Hz to a single 12VDC 4A or 24VDC 3A Class 2 output, which suits mixed systems where you may later move the same cabinet to 24V. Choose by whether the head end is brand specific or open.
18) There is no AC power at the gate - what can I use instead of the AL400UL?
The AL400UL requires a 115VAC/60Hz input at 3.5A, so it needs a mains feed. Where no line power is available, the Securitron BPSS is a boxed solar power supply and is the option in the group that does not depend on an AC branch circuit. Verify the site's daily load against the solar unit's capability, since it will not match the AL400UL's 4A at 12VDC continuous rating.
19) Is the AL400UL suitable for commercial building installs or is it a residential unit?
It is rated for commercial use, which is the category it belongs in for access control, CCTV and fire alarm work in multi-family, institutional and commercial buildings.
