Altronix AL400ULX Power Supply Charger

The AL400ULX converts a 115VAC/60Hz input into a single 12VDC or 24VDC output, selected at the unit, so one part number covers both. It is a single-output supply, so everything you feed from it runs at whichever voltage you select. If you have a mix of 12V strikes and 24V mag locks on the same opening, you need a second supply or a multi-voltage board.

The AL400ULX is rated 3A. That covers a typical pair of magnetic locks or several electric strikes with margin, but size it against the actual inrush and holding draw of your devices plus any reader or REX load on the same output. Motorized latch retraction exit devices are the usual exception, they draw heavy inrush and generally want a supply built for that duty.

Enclosure is included. The AL400ULX ships as an enclosure with the charger board and a single Class 2 output, so it mounts on the wall as a finished unit. What is not included is the standby battery itself, the board is a charger and you add sealed lead acid batteries sized to the backup time you need.

No. The AL400ULX gives a single Class 2 output, so every device on it switches together unless you add a downstream access power controller. For a job that needs separate fused and switched outputs per door, look at something like the RCI DKPS-2A, which is a 12/24VDC 2A supply with eight outputs for access control systems.

Motor latch retraction draws a high inrush current at actuation and is normally powered by a supply built for that duty rather than a general purpose access control supply. The AL400ULX is a 3A general purpose 12/24VDC supply with a single Class 2 output. For MLR openings, the BEST RPSMLR2 is a power supply specifically for motorized latch retraction exit devices. Delayed egress exit devices have their own dedicated option as well: the BEST PS161-6 takes 120V input with 12/24V output at 6A capacity.

The AL400ULX is a 3A supply that converts 115VAC/60Hz input into a single 12VDC or 24VDC Class 2 rated power limited output, shipped with an enclosure and charger. The nearest peer on output is the Securitron AQL4, a switching power supply rated 12/24VDC at 4/3 amps, which covers the same dual-voltage selection at comparable current. The SDC 634 is a 4 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 632 is the 2 amp version of that same regulated family if 3A is more than the opening needs. The main distinction is construction: the Securitron AQL4 is described as switching, the SDC units as regulated and filtered linear supplies.

Yes. The AL400ULX is rated 3A, which is more than a single low-draw device typically needs. For a lighter load, the SDC 620 is a 1 amp regulated and filtered low voltage supply with dual voltage selection, the Securitron AQD1 is a 12/24 VDC switching supply at 1 amp, and the Command Access PS1 is a 24VDC linear supply with 1 amp output if the device is 24V only. The SDC 631 sits between them at 1.5 amps with dual voltage selection. Note the AL400ULX ships with an enclosure and charger for battery standby, so if backup is required the smaller units need to be checked against that requirement separately.

The AL400ULX provides a single 12VDC or 24VDC Class 2 rated power limited output, so distribution to multiple doors has to be handled 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. Compare the current figures before switching: the DKPS-2A is a 2A unit against the AL400ULX at 3A, so the total connected load across those eight outputs is the number to check.

The AL400ULX ships with an enclosure and a charger, so standby batteries can be added inside the can. Peers that also state battery backup are the Adams Rite PS-1, a regulated 1 amp 12/24 volt DC supply with battery backup, and the Command Access PS204/204B, a linear supply with 2A at 24VDC and battery backup. The Detex 10-800 is a different animal - it is a universal logic controller with a 120VAC/24VDC power supply and battery backup, so it brings control logic along with the power rather than being a straight supply.

Three to rule out. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V - it carries power through the door edge and generates none, so it is a companion to a supply, not a replacement. The Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries, intended for bench and field testing rather than permanent installation. The BEST ELR150 is a power supply control module, which switches and controls power in an access control system rather than converting 115VAC as the AL400ULX does.

Class 2 power limited means the output is current and voltage limited, which is what lets you run the low voltage wiring for locks and readers without the conduit and wiring method rules that apply to line voltage. The AL400ULX delivers a single 12VDC or 24VDC Class 2 rated power limited output from a 115VAC/60Hz feed, so the field wiring off it is low voltage Class 2 cabling.

It is a power supply/charger, so it float charges standby batteries and carries the load through a loss of the 115VAC input. You supply the batteries. Remember that fail safe devices like mag locks stay locked on battery, so your egress path still needs its mechanical or hardwired release regardless of the backup.

Commercial duty, wired to a standard 120V branch circuit. The board takes 115VAC at 60Hz, so a dedicated unswitched 120V circuit at the equipment room or the door head is the normal feed. Do not put it on a circuit that gets killed by a light switch or a breaker used for anything a tenant controls.

Several 12/24VDC field selectable supplies sit in the same slot. The Securitron AQL4 is a switching supply at 12/24VDC, 4/3A. The Von Duprin PS902 is a 2A 12/24VDC field selectable base supply for access control. The SDC 634 is a 4 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 632 is the 2 amp version. Where the AL400ULX differs from the plug in and open board options is that it arrives as a boxed charger with a Class 2 output.

For a single low draw strike, yes, 3A with a charger and enclosure is more supply than the job needs. A 1 amp unit such as the Command Access PS1 24VDC linear supply or the Securitron AQD1 switching supply at 12/24VDC 1 amp is the smaller fit. Go with the AL400ULX when you want the boxed enclosure and battery charging, or when you expect to add doors later.

Both are field selectable 12/24VDC access control supplies fed from line voltage. The AL400ULX is rated 3A and converts a 115VAC/60Hz input to a single Class 2 rated power limited output, supplied with an enclosure and charger. The Von Duprin PS902 is a base power supply rated 2A, 12/24 VDC field selectable for access control, and carries a Grade 1 designation. The PS902 is described as a base unit, which is the usual arrangement where option boards are added for relay or fire alarm functions.

Only for small single-device jobs, and the mounting is different. The AL400ULX is hardwired from a 115VAC/60Hz source and comes in an enclosure with a charger, which suits a wall-mounted permanent install. The ROFU 9126T is a plug in mini power supply at 12 VDC and 1.5A with a built-in time delay, which serves a single strike from a receptacle and adds timing the AL400ULX does not provide. The ROFU 9102-12D UL/9102-24D is a boxed supply taking 10/120VAC 60Hz input if you want line-voltage wiring in a 12V or 24V fixed-output form.

The AL400ULX is rated 3A with a single 12/24VDC Class 2 output. Moving up, the Securitron AQS1210 is a switching supply at 12 VDC and 10 amps if the system is 12V throughout, and the Aiphone AC-PS1250 is a 12V DC 5A UL listed supply intended for AC Series access control kits. If the system runs 24V, the BEST PS161-6 provides 12/24V output at 6A capacity from a 120V input. Confirm whether your devices need dual-voltage selection before choosing, since the AQS1210 and AC-PS1250 are 12V only.

The AL400ULX needs a 115VAC/60Hz feed to operate, so it is not an option on a gate or remote opening with no line power. The Securitron BPSS is a boxed solar power supply, which addresses exactly that condition. For temporary or bench powering where you just need voltage at the device, the Command Access CAT Field Tester is a portable 12-24VDC supply that runs from DeWalt, Makita and Milwaukee tool batteries.

The AL400ULX delivers a straight 12VDC or 24VDC Class 2 power limited output at 3A with no boost function stated. The Command Access PS210 is a UL 6E/CSA linear power supply with 1.5A at 24VDC and boost circuitry, which is the one to look at when voltage drop over a long run to a 24V device is the concern. The tradeoff is current: 1.5A on the PS210 against 3A on the AL400ULX, and the PS210 is 24VDC where the AL400ULX is selectable between 12 and 24.

The AL400ULX is supplied with its enclosure, charger and single Class 2 output as one package. Among the peers that also state a boxed or enclosed form: the Locknetics LP Series 150 and 250 amp power supply is offered with enclosure, the Securitron BPSS is a boxed solar power supply, and the ROFU 9102-12D UL/9102-24D is likewise a boxed unit taking 10/120VAC 60Hz input. Smaller units like the ROFU 9126T are plug in mini supplies with no wall can at all.
