ALTRONIX SMP5 multi-voltage power supply

The ALTRONIX SMP5 is a new AT-type power supply that delivers selectable 6 VDC, 12 VDC or 24 VDC outputs at up to 4 A. It is built for installers and system integrators who need a single unit to power access-control panels, CCTV cameras or other low-voltage security devices from one enclosure. The phenolic or fiberglass chassis suits rack or wall mounting in commercial environments.

Output limits and wiring considerations

The supply provides a combined 4 A across the three voltage taps, so total connected load must stay within that figure; drawing the full 4 A at 24 V leaves no headroom for the 6 V or 12 V rails. Voltage is selected per output, not regulated simultaneously, so each circuit must be wired to the correct terminal for its required level. Cable voltage drop over long runs can reduce the effective voltage at the device, so plan conductor gauge accordingly.

Questions about this item

Which output voltage should I select for a 12 VDC device?

Choose the 12 VDC output; the unit also provides 6 VDC and 24 VDC taps for other loads.

What does the 4 A rating mean when the supply is installed?

The 4 A rating is the total current available across all three outputs combined, not per individual output.
