3-phase universal SMPS · 5 V / 2.5 A

3 Phase Switch Mode Power Supply (SMPS)

Any two wires. A steady 5 volts.

A compact DC power supply that runs from any two conductors of a 3-phase supply: two phases at 415 V, or one phase and neutral at 240 V.

Applications

Clean 5 V wherever the panel has phases

Pump and starter controllers

Stays powered through single-phasing and swings, so the controller can protect the motor.

Valve and zone controllers

Powers scheduling logic and radio modules from the nearest feeder.

Gateways, modems, sensors

Runs GSM and LoRa gateways and loggers on sites with unreliable mains.
