Altronix SMP10 – Frequently Asked Questions

1) What input does the Altronix SMP10 power supply board need, and does it plug into a 120V wall outlet?
The SMP10 board takes a low voltage AC input of 24/28VAC, so it does not connect to line voltage directly. You feed it from a transformer on the 120V side, and the board converts that low voltage AC into regulated DC. Plan the enclosure and transformer accordingly when you lay out the access control cabinet.
2) Can the SMP10 run 24VDC maglocks and 12VDC strikes, or do I have to pick one voltage?
Output on the SMP10 is selectable, 12VDC or 24VDC, but it is one selection for the board. Whichever you set, the whole 10A of continuous supply current comes out at that voltage. If you have a mixed opening with 12V strikes and 24V mags, you need a second supply or a board set for each voltage rather than trying to split this one.
3) How many electric strikes or maglocks will a 10 amp Altronix supply actually carry?
Budget against 10A of continuous supply current at your selected voltage. Add the holding current of every lock, plus readers, controllers, and rex devices on the same board, and size to the total draw with headroom for inrush. The outputs are filtered and electronically regulated, so devices sensitive to ripple (readers, cameras) run off it without a separate conditioned supply.
4) Does the SMP10 have battery backup built in, and do the batteries come with it?
There is a built-in charger for sealed lead acid or gel type batteries on the SMP10, with a maximum charge current of 0.7A. Batteries are not included, so order them separately and match them to the output voltage you have selected. Switchover to battery backup happens with zero voltage drop, which matters on access control where a momentary sag can drop a controller or unlatch a door.
5) Can a Command Access DS1+ board be used in place of an Altronix SMP10 to power access control devices?
No. The Altronix SMP10 is a switching power supply/charger board that converts 24/28VAC input into 12VDC or 24VDC selectable output at 10A of continuous supply current, with a built-in charger for sealed lead acid or gel batteries. The Command Access DS1+ is a delay/sequencer board with bi-directional control operating at 12-24VDC, meaning it takes DC power in and sequences devices rather than generating supply current. The two work alongside each other in a cabinet, with the SMP10 producing the 12 or 24VDC and the DS1+ timing the sequence, but the DS1+ cannot substitute for the supply.
6) Will the SMP10 board survive in an unconditioned electrical room or a parking garage?
Operating range on the SMP10 runs 0 to 49 degrees C (32 to 120 degrees F), with relative humidity to 85 percent plus or minus 5 percent. Storage tolerance is wider, -20 to 70 degrees C (-4 to 158 degrees F). An unheated garage that drops below freezing is outside the operating window, so that install needs a conditioned or heated enclosure location.
7) What protects the SMP10 if an installer shorts a lock lead or the board gets overloaded?
Short circuit and thermal overload protection are built into the SMP10 outputs. A pinched lock wire in a hinge or a crossed pair at the strike will not take the board out. AC input and DC output LED indicators sit on the board, so a tech at the enclosure can tell at a glance whether the transformer is feeding it and whether DC is present downstream.
8) Is the SMP10 a raw board or a complete power supply in a cabinet?
The SMP10 is the power supply and charger board itself, not a boxed assembly. You are supplying the enclosure, the transformer to feed it 24/28VAC, and the batteries. That suits a retrofit where you already have a can and a transformer and just need the converting and charging electronics replaced or added.
9) I need a board to sequence two doors or delay a maglock release, will the SMP10 do that?
No. The SMP10 converts and regulates power and charges standby batteries, it does not sequence or time anything. For door sequencing look at the Command Access DS1-X multi-function door sequencing relay board, which carries 13 programmable functions, or the DS1+ delay/sequencer board with bi-directional control at 12-24VDC. Those are logic boards that sit downstream of a supply like the SMP10, not replacements for it.
10) What is the difference between the Command Access DS1-X and the Altronix SMP10 on a door with multiple devices to trigger?
They solve different halves of the opening. The Command Access DS1-X is a multi-function door sequencing relay board with 13 programmable functions, so it handles the order and timing in which a strike, operator, and lock release fire. The Altronix SMP10 supplies the power those devices run on, delivering 12VDC or 24VDC selectable at 10A with filtered and electronically regulated outputs, short circuit and thermal overload protection, and zero voltage drop when switching over to battery backup. A sequenced opening typically needs both boards, not one or the other.
11) How much heat does a 10A access control power supply throw into the enclosure?
Heat output on the SMP10 is roughly 61 BTU/Hr at 12VDC and 123 BTU/Hr at 24VDC. Run it at 24V in a small sealed can stacked with controller boards and that is real heat to account for, particularly at the top of the 120 degree F operating limit.
12) Is the Altronix SMP10 suitable for a commercial building, or is it a residential-grade supply?
Commercial. The SMP10 is built for access control, security, and CCTV accessories that need supplemental power, and at 10A it is sized for multi-door commercial work rather than a single residential opening. Institutional and multi-family facilities standardizing on one supply platform can run the same board at 12V or 24V depending on the lock type at each building.
13) Is a 12-24VDC sequencer board like the Command Access DS1+ enough to run a 24VDC opening on its own?
The Command Access DS1+ is specified for 12-24VDC operation, which describes the voltage it works with, not a supply it produces. The current for the devices has to come from a supply board such as the Altronix SMP10, which is selectable for 12VDC or 24VDC output at 10A of continuous supply current, is rated for commercial use, and dissipates approximately 61 BTU/Hr at 12VDC and 123 BTU/Hr at 24VDC for enclosure heat planning. Size the supply to the total device load, then let the DS1+ handle the bi-directional control.
