Altronix SMP3PMP4CB – Frequently Asked Questions

1) How many devices can I power from one Altronix SMP3PMP4CB, and how much current do I have to work with?
Four outputs, PTC protected, sharing 2.5A total at either 12VDC or 24VDC. Add up the draw of every device you want to hang off it (strikes, maglocks, readers, controllers) and keep the total under 2.5A. Four maglocks at typical holding draw will use most of it, so size accordingly before you split the load.
2) Is the SMP3PMP4CB 12 volt or 24 volt?
Either. The SMP3PMP4CB converts its AC input into four outputs that run at 12VDC or 24VDC, so one unit covers a 12V strike job or a 24V maglock job. The selection applies to the supply, so plan on all connected devices sharing the same voltage.
3) What should I use instead of the Altronix SMP3PMP4CB if the load draws more than 2.5A?
Step up to a higher-current supply. The SDC 634 Series is a 4 Amp regulated and filtered low voltage supply with dual voltage selection, the Securitron AQL4 is a switching supply at 12/24VDC 4/3Amp, and the Securitron AQS1210 is a 12 VDC 10 Amp switching supply for large 12-volt loads. The Altronix SMP3PMP4CB is rated 2.5A across its four 12/24VDC outputs, so total connected draw has to stay inside that.
4) What is the closest multi-output alternative to the Altronix SMP3PMP4CB for an access control panel?
The RCI DKPS-2A is the nearest multi-output equivalent. It provides eight outputs at 12/24VDC rated 2A for access control systems, while the Altronix SMP3PMP4CB converts a 115VAC/230VAC 50/60Hz input into four 12VDC or 24VDC outputs rated 2.5A. If the job needs more than four separately protected runs from one can, the DKPS-2A is the one to spec; if four outputs cover the openings and you want the higher per-supply current, stay with the SMP3PMP4CB.
5) What does the PTC protection on the Altronix SMP3PMP4CB outputs actually do for me on an access control job?
Each of the four outputs is individually PTC protected, meaning a short or overload on one door trips that circuit only and it resets itself once the fault clears. You are not replacing fuses or losing the other three openings while you chase the problem, which matters when the supply is feeding several doors in a building you do not visit daily.
6) Does the Altronix SMP3PMP4CB come with an enclosure, or do I have to buy one?
The grey enclosure is included, along with the battery charger circuit and the four PTC protected outputs. What is not in the box is the standby battery itself, so order batteries separately if you need the supply to ride through a power loss.
7) What does supervised mean on an access control power supply like the SMP3PMP4CB?
Supervised, in the sense Altronix uses it on the SMP3PMP4CB, means the unit monitors its own AC input and its battery charging circuit rather than simply putting out DC and hoping. It is a charger as well as a supply, so a connected standby battery is kept topped up and carries the load if the 115VAC or 230VAC input drops.
8) Is the Von Duprin PS902 a substitute for the Altronix SMP3PMP4CB?
They overlap but are not the same build. The Von Duprin PS902 is a base power supply rated 2A at 12/24 VDC, field selectable for access control, and carries a Grade 1 designation. The Altronix SMP3PMP4CB is a supervised supply/charger delivering four PTC protected 12/24VDC outputs at 2.5A from a 115VAC or 230VAC 50/60Hz input, with the charger and enclosure included. Choose the PS902 if the specification calls out Von Duprin electrical products for a Von Duprin device; choose the SMP3PMP4CB when you need four protected output runs and dual-input voltage from one box.
9) What looks like a substitute for the Altronix SMP3PMP4CB but is not?
A few items sit nearby and do a different job. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V, which carries power through the door rather than generating it. The Command Access CAT Field Tester is a portable 12-24VDC test supply that runs off DeWalt, Makita and Milwaukee batteries, for bench and field checks rather than permanent installation. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC supply and battery backup, so it adds control logic beyond straight power. The Altronix SMP3PMP4CB is a fixed-mount supervised supply/charger with four 12/24VDC outputs at 2.5A.
10) Which alternatives to the Altronix SMP3PMP4CB include battery backup?
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 linear supply with 2A at 24VDC and battery backup, and the Detex 10-800 Series pairs a 120VAC/24VDC supply with battery backup. The Altronix SMP3PMP4CB includes a charger in its enclosure alongside the four PTC outputs, so standby batteries are wired into the same can.
11) Is the Altronix SMP3PMP4CB suitable for a commercial building or is it a residential-grade supply?
It is a commercial unit, intended for access control installations in commercial buildings. Typical use is feeding electric strikes, maglocks, readers and controllers from a single wall-mounted grey enclosure on a 115VAC or 230VAC branch circuit.
12) How does the Altronix SMP3PMP4CB compare with the SDC 631 and 632 supplies?
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 supply with dual voltage selection; both are single-output boxes chosen by amperage. The Altronix SMP3PMP4CB splits its capacity across four PTC protected 12/24VDC outputs at 2.5A and includes a charger, so devices on separate doors can be fused apart from one another.
13) For a small plug-in application, what is a lighter-duty option than the Altronix SMP3PMP4CB?
The ROFU 9126T is a plug-in mini power supply at 12 VDC / 1.5A with time delay, which suits a single strike where no enclosure or distribution is wanted. The ROFU 9102-12D UL / 9102-24D runs on 10/120VAC 60Hz input for a boxed single-voltage install. The Altronix SMP3PMP4CB is a hardwired supervised unit shipped in a grey enclosure with a charger and four PTC protected 12/24VDC outputs at 2.5A.
