Altronix SMP3ET – Frequently Asked Questions

1) What output voltage and current does the Altronix SMP3ET power supply deliver?
The SMP3ET is a single-output power supply/charger rated 2.5A, with a field-selectable 6VDC or 12VDC output. It takes a low voltage AC input and converts it to that DC output, so you size your load list against 2.5 amps total at whichever voltage you select.
2) Will the SMP3ET keep my locks powered if the building loses power?
It is a power supply/charger, meaning it maintains standby batteries as well as running the load. The charger function is built in and the unit ships in its enclosure. Batteries themselves are sized and bought separately based on how long you need the doors to hold up.
3) Is a 2.5A single-output supply enough for a multi-door access control job?
With one output at 2.5A, the SMP3ET suits a single opening or a small load group where you can bus the power yourself. If you need power distributed to several doors with individual protected outputs, look at a multi-output unit instead, such as the RCI DKPS-2A with 8 outputs at 12/24VDC or the BEST PS161-6 at 6A. Those are built for spreading current across openings.
4) I need 24VDC for my electric strike. Can the SMP3ET do that?
No. The SMP3ET outputs 6VDC or 12VDC only, so a 24V strike or maglock will not run on it. For 24V you want a dual-voltage or 24V unit such as the Securitron AQD1 at 12/24VDC 1A, the Command Access PS1 at 24VDC 1A, or the Von Duprin PS902 at 2A 12/24VDC field selectable.
5) What is the closest equivalent to the Altronix SMP3ET if I need 12VDC at around 2 amps for an access control door?
The Altronix SMP3ET puts out 6VDC or 12VDC at 2.5A from a low voltage AC input. If you want a comparable single-door supply in the same current class, the SDC 632 Series is a 2 amp regulated and filtered low voltage power supply with dual voltage selection, and the Von Duprin PS902 is a 2A 12/24VDC field selectable base power supply for access control. The Von Duprin unit and the SDC unit are both field selectable between two DC voltages, while the SMP3ET selects between 6VDC and 12VDC.
6) I need 24VDC, not 12 - what should I use instead of the Altronix SMP3ET?
The Altronix SMP3ET outputs 6VDC or 12VDC only, so a 24V device needs a different supply. The Command Access PS1 Series is a 24VDC linear power supply with 1 amp output, and the Command Access PS204/204B is a linear power supply with 2A at 24VDC plus battery backup. If you want a unit that covers both voltages, the SDC 634 Series is a 4 amp regulated and filtered supply with dual voltage selection, and the Securitron AQL4 is a switching supply rated 12/24VDC at 4/3 amps.
7) The Altronix SMP3ET only has one output - what do I use to feed several doors from one enclosure?
The SMP3ET ships as an enclosure, charger and single output, so each unit feeds one load. For multi-door distribution, the RCI DKPS-2A provides 8 outputs at 12/24VDC and 2A for access control systems. The BEST PS161-6 is a 120V input, 12/24V output supply rated at 6A capacity for delayed egress exit devices, which gives you more headroom to split across openings.
8) Does the Altronix SMP3ET come with a cabinet or do I have to buy one?
An enclosure is included, so the board arrives ready to mount on a wall or in a closet rather than as a bare PCB. Nothing extra is needed to house it.
9) What are my options if I want the power supply and access control logic in one box instead of a standalone charger?
The SMP3ET is a straight power supply/charger with one output and no control logic. If you want switching, timing, or logic built in, the Detex 10-800 universal logic controller pairs a 120VAC/24VDC supply with battery backup in one unit, the ROFU 9126T is a plug-in 12VDC 1.5A supply with a time delay, and the BEST ELR150 is a power supply control module for electronic access control.
10) Is there a smaller or simpler alternative if I don't need 2.5 amps?
If your load is light, the Securitron AQD1 is a switching power supply rated 12/24 VDC at 1 amp, the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the ROFU 9126T is a plug-in mini power supply at 12VDC and 1.5A with a built-in time delay. The Altronix SMP3ET carries 2.5A and comes with an enclosure and charger, so it suits loads that need battery standby rather than a bare plug-in module.
11) What items look like substitutes for the Altronix SMP3ET but are not power supplies?
A few nearby parts are not drop-in replacements. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V - it moves power through the door rather than generating it. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs on DeWalt, Makita and Milwaukee batteries for bench and field testing. The BEST ELR150 Series is a power supply control module, and the Detex 10-800 Series is a universal logic controller that includes a 120VAC/24VDC supply and battery backup. The Altronix SMP3ET itself is the boxed supply and charger with a single 6/12VDC output.
12) Which alternatives to the Altronix SMP3ET include battery backup?
The Altronix SMP3ET includes a charger in the enclosure for standby battery use. Among comparable units, the Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC 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 controller includes a 120VAC/24VDC power supply with battery backup.
13) I need a UL listed 12V supply with more than 2.5 amps - what are my options besides the Altronix SMP3ET?
For larger 12V loads, the Aiphone AC-PS1250 is a UL listed 12V DC 5A supply used with AC Series access control kits, and the Securitron AQS1210 is a 12 VDC 10 amp switching power supply. The Altronix SMP3ET is a 2.5A unit with a single output, so it suits one opening rather than a bank of strikes or maglocks.
