Altronix AL125ULP – Frequently Asked Questions

1) How much current can the Altronix AL125ULP actually deliver at 12VDC and at 24VDC?
The AL125ULP gives you 12VDC at 1A or 24VDC at 0.5A, across two individually PTC protected outputs. That total is the budget for everything you hang off it, so add up the holding current of your strikes, maglocks or cameras before you commit. If the load runs past 1A at 12V, step up to a larger supply such as the Securitron AQL4 (12/24VDC, 4/3A) or the RCI DKPS-2A (12/24VDC at 2A with eight outputs).
2) Does the Altronix AL125ULP plug into a standard 120V wall outlet or does it need to be hardwired?
It runs off a plug-in transformer that ships with the unit, so there is no line-voltage hardwiring. The transformer takes 120V and feeds the board 24VAC at 40VA. That makes it a practical retrofit where you have a receptacle near the door or the camera head end but no spare breaker or conduit run.
3) Is a battery included with the AL125ULP, or do I have to buy one separately?
The AL125ULP is a power supply/charger, meaning the charging circuit for a standby battery is on board, but what ships is the enclosure, the charger, the two PTC Class 2 outputs and the plug-in transformer. The battery itself is not part of the package, so order it with the unit if you need the outputs to ride through a power loss.
4) Can I run one output at 12V and the other at 24V on the Altronix AL125ULP?
No. The board converts the 24VAC input into two outputs at 12VDC or 24VDC, and the voltage selection applies to the unit, not per output. Both outputs run at whichever voltage you set. If you need a 12V device and a 24V device fed from one box, use two supplies or a multi-output controller like the RCI DKPS-2A.
5) Which of these power supplies is the right one for an electrified exit device with motorized latch retraction?
Not the AL125ULP - it is rated at 1A and is intended for general use, CCTV, fire alarm and POIP loads. Motorized latch retraction devices draw a large inrush and call for a supply built for them: the BEST RPSMLR2 Series is a power supply specifically for motorized latch retraction exit devices. For delayed egress exit devices, the BEST PS161-6 takes a 120V input and delivers 12/24V output at 6A capacity.
6) What is the closest equivalent to the Altronix AL125ULP if I need a 1 amp 12/24VDC switching supply from another brand?
The Securitron AQD1 is a switching power supply rated 12/24 VDC at 1 amp, which lines up closely with the AL125ULP's 1A current rating and its two individually PTC protected 12VDC or 24VDC outputs. The difference to weigh is output count and input: the AL125ULP takes a 24VAC 40VA input from its included plug-in transformer and splits it into two PTC protected outputs, while the AQD1 is described simply as a 12/24 VDC switching supply. If you are feeding two separate loads from one box, the AL125ULP's dual PTC outputs are the reason to keep it.
7) I need more than 1 amp for a bank of maglocks - what should I use instead of the AL125ULP?
The AL125ULP is rated at 1A, so a larger load needs a bigger supply. The Securitron AQL4 is a 12/24VDC switching supply rated 4/3 amp, and the Securitron AQS1210 is a 12 VDC 10 amp switching supply. On the linear side, the SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 632 Series is the 2 amp version of the same family. Total the holding current of every lock plus any reader or controller draw, then pick the supply above that number.
8) What are my options if I need battery backup and the AL125ULP alone will not cover it?
Several peers pair the supply and the standby battery in one part. The Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC supply with battery backup, matching the AL125ULP's 1A rating while adding the backup function. The Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup, and the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC supply and battery backup for openings that also need egress logic.
9) I need multiple protected outputs for several doors - does the AL125ULP do that or should I look at something larger?
The AL125ULP gives you two individually PTC protected outputs from a single 24VAC 40VA input, which covers two circuits. For a larger door count, the RCI DKPS-2A is a power supply with 8 outputs at 12/24VDC and 2A for access control systems. Count the doors and the per-door draw first - two circuits at a combined 1A is the ceiling on the Altronix unit.
10) My spec sheet calls for a 2A field selectable 12/24VDC supply for access control - which part matches?
The Von Duprin PS902 is a base power supply rated 2A, 12/24 VDC field selectable for access control, and it carries a Grade 1 designation. The AL125ULP is the lighter unit at 12VDC 1A or 24VDC 0.5A, with two individually PTC protected outputs and an included plug-in transformer. If the drawing specifies 2A, go to the PS902; the Altronix unit will not meet that number.
11) What does PTC protection on the AL125ULP outputs mean for my install?
Each of the two outputs is individually PTC protected, so a short or overload on one circuit trips that leg without taking the other down and without a fuse to replace. Clear the fault, the PTC resets itself and the output comes back. For a two-door or camera-plus-device install that means one bad run does not kill the whole panel.
12) Is the Altronix AL125ULP suitable for fire alarm and CCTV, or only access control?
It is used for general purpose power, CCTV, fire alarm and PoIP work. The Class 2 outputs and the 40VA UL Listed Class 2 transformer are what make it acceptable in low voltage life safety and camera power runs. It is a commercial-duty unit, not a residential plug pack.
13) How does the Altronix AL125ULP compare to a Securitron AQD1 or an SDC 620?
All three land in the same 1 amp class. The Securitron AQD1 is a 12/24VDC 1 amp switching supply and the SDC 620 is a 1 amp regulated and filtered low voltage supply with dual voltage selection. What separates the AL125ULP is the on-board charger for standby battery and the two separately PTC protected outputs rather than a single feed. If you want more headroom in the same family of products, the SDC 631 is 1.5A and the SDC 632 is 2A.
14) Do I need a control module in addition to a power supply like the AL125ULP?
It depends on what the opening has to do. The AL125ULP supplies power - it converts a 24VAC 40VA input into two individually PTC protected 12VDC or 24VDC outputs, with no switching logic. If the job also calls for control functions, the BEST ELR150 Series is a power supply control module for electronic access control, and the Detex 10-800 Series is a universal logic controller with its own 120VAC/24VDC supply and battery backup.
15) What is the difference between the Altronix AL125ULP and a plug-in supply like the ROFU 9126T?
The AL125ULP is a boxed unit - it ships with a grey enclosure, charger, two PTC Class 2 outputs and a plug-in transformer, and it is rated 12VDC at 1A or 24VDC at 0.5A. The ROFU 9126T is a plug-in mini power supply rated 12 VDC at 1.5A with a built-in time delay. If you need a single 12VDC feed with a timer and no wall box, the 9126T is the simpler part; if you need an enclosed unit feeding two separately protected circuits, or a 24VDC output, stay with the AL125ULP.
16) Is the Command Access PS1 a substitute for the Altronix AL125ULP?
They overlap on amperage but not on output voltage flexibility. The Command Access PS1 Series is a 24VDC linear power supply with a 1 amp output, so it is fixed at 24VDC. The AL125ULP is a switching supply whose two outputs can each be set for 12VDC or 24VDC, rated 12VDC at 1A or 24VDC at 0.5A. On a 24VDC device drawing more than half an amp, the PS1 is the one that carries it; on a mixed 12V and 24V pair of loads, the AL125ULP covers both from one box.
17) What looks like a substitute for the AL125ULP but is not actually a power supply?
Two parts in the same aisle are easy to mis-order. 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 across the door, it does not generate it. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs off DeWalt, Makita and Milwaukee batteries, meant for bench and field testing rather than permanent installation. The AL125ULP is the fixed supply itself, shipping with an enclosure, charger and plug-in transformer.
18) How does the AL125ULP compare with the SDC 620 and SDC 631 supplies?
All three are in the same size class. The SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller, also with dual voltage selection. The AL125ULP is a switching type unit rated 12VDC at 1A or 24VDC at 0.5A with two individually PTC protected outputs and a grey enclosure. If the job needs a single higher-current 12 or 24V feed, the 631 gives you the extra half amp; if it needs two separately protected circuits, the Altronix layout is the one that splits them.
19) Is there an alternative to the AL125ULP for a site with no AC power at the door?
Yes. The AL125ULP runs from a 120V source through its included plug-in transformer, so it needs utility power at the location. The Securitron BPSS is a boxed solar power supply, which is the option for a gate, remote entry or outbuilding with no AC feed available.
20) Will the AL125ULP power an intercom or access control kit, or do I need the manufacturer's own supply?
Check the kit's current draw against the AL125ULP's rating of 12VDC at 1A or 24VDC at 0.5A. The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply built for Aiphone AC Series access control kits, so a kit written to that spec wants the higher-current unit. The AL125ULP comes from a UL Listed Class 2 transformer and suits general use, CCTV, fire alarm and POIP loads within its 1A ceiling.
21) Does the Altronix AL125ULP come with its own enclosure for mounting in an electrical room?
Yes, the board ships in a grey enclosure, so it mounts as a self-contained unit on a wall or backboard rather than needing a separate can. The plug-in transformer is external, which means you need an outlet within cord reach of wherever the box lands.
