Altronix SMP7PMCTX220 Supervised Power Supply/Charger 220VAC
Overview
The Altronix SMP7PMCTX220 is a single-output, supervised power supply and battery charger designed for security installations where the local mains run at 220VAC — common across international deployments, industrial facilities, and commercial sites in regions outside North America's 120VAC grid. It accepts a 220VAC 50/60Hz input and converts it to a selectable 12VDC or 24VDC output at 6A continuous, giving you enough headroom for multi-device panels, access control hardware, or camera power runs in a single, wall-mounted enclosure. If you are speccing out a project requiring regulated DC power with supervised battery backup on a 220VAC circuit, the SMP7PMCTX220 belongs on your short list.

Key Features
- Selectable 12VDC or 24VDC Output at 6A: A single unit that covers both common security device voltages. Instead of stocking two separate supplies for mixed 12V/24V deployments, you configure on-site — useful when device specs are locked in late in a project.
- 220VAC Input (198–256VAC Working Range): The wide input tolerance — nearly 30% swing above and below nominal — means the supply keeps regulating through utility voltage fluctuations common in developing markets and industrial buildings without tripping or damaging downstream devices.
- 50/60Hz Dual Frequency Acceptance: Works on both European 50Hz and international 60Hz grids without modification. No frequency selector switch to forget.
- Electronically Regulated, Filtered Output: The output is not just stepped down — it is electronically regulated and filtered. Sensitive microprocessor-based access control boards and IP camera power inputs get clean DC, not a ripple-prone transformer-only supply that causes random resets.
- Short-Circuit and Thermal Overload Protection: Both fault modes are handled internally. A shorted output or overheated enclosure shuts the supply down rather than damaging downstream equipment or starting a fire — critical in unmonitored equipment rooms.
- Built-in Battery Charger (0.7A, SLA/Gel Compatible): The onboard charger handles sealed lead-acid and gel-type batteries at up to 0.7A. The enclosure accommodates up to two 12VDC/7AH batteries (sold separately), and switchover is zero-voltage-drop — no relay click, no momentary power loss to the panel or cameras during a mains failure.
- AC Fail and Battery Supervision via Form C Contacts: Both AC input loss and battery conditions (presence and low battery) report through dry-contact Form C relay outputs. Wire these into your alarm panel or BMS to get real-time power fault alerts rather than discovering a dead supply during an incident.
- Power ON/OFF Switch + LED Indicators: Dedicated AC input and DC output LEDs give field technicians immediate visual confirmation of supply status without pulling a meter — speeds commissioning and troubleshooting.
- 330VA AC Input Requirement: Size your UPS or generator circuit accordingly. At 330VA input demand, a 500VA UPS upstream gives comfortable margin for transient startup loads.
