Best Fit & Recommended For
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. The Chicago go-to for compact single-device installations where the larger AL400ULX or AL600 series is over-spec.
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.
Where the Altronix SMP3ET Wins in Chicago
- Compact access control panel auxiliary power
- Low-current legacy CCTV cameras (6 VDC)
- Intercom auxiliary power
- Small-device alarm system power
- Healthcare clinic small-device power
- Education facility single-device deployments
- Multi-tenant residential single-output applications
- Hospitality back-of-house compact-device power
- Retail back-of-house single-device applications
