Altronix SMP3ET Compact Power Supply / Charger (6 / 12 VDC @ 2.5A)

Altronix SMP3ET Compact Power Supply / Charger

The Altronix SMP3ET is the compact single-output power supply / charger from Altronix’s SMP series — selectable 6 VDC or 12 VDC output at 2.5 A continuous, with built-in charger for sealed lead-acid / gel batteries and automatic switchover to backup power on AC loss. For one intercom or one small panel there’s no reason to hang a full AL400ULX — this compact unit covers it.

What’s Confirmed by the Official Altronix Spec

These specifications come from Altronix’s published SMP3ET product documentation:

• Output (selectable): 6 VDC or 12 VDC at 2.5 A continuous
• Output conditioning: filtered and electronically regulated; short-circuit and thermal overload protection
• Battery backup: built-in charger for sealed lead-acid / gel batteries; automatic switchover to standby battery on AC failure

When SMP3ET Fits — Compact Single-Device

The SMP3ET is the right pick when:

• The application is a single low-current device (one IP camera, one intercom, one small access panel)
• The current budget is under 2.5 A at 12 VDC (or 6 VDC for legacy cameras)
• A battery backup is required but the larger 4 A budget of the AL400ULX is unnecessary

For multi-output applications, see the AL600ULMX (5 outputs) or ALTV1224DC2 (16 outputs). For larger single-output applications, see the AL400ULX.
