Three phase power supply for smart grids, CATIV/300V, nominal output 24V, 30-35W, with battery backup option

The PWR 3 and PWR 1 power supplies are designed for applications in distribution substation automation projects with a high over-voltage category, wide range of input voltages and wide operation temperature range. The standard PWR 3N as well as PWR 3A power supplies are connected to a three-phase auxiliary voltage where each line can supply the DC side in case of a failure on any of the other lines. PWR 3A offers an additional UPS function with embedded charging controller for an external lead accumulator.

The output of the PWR power supply is safely isolated with SELV output voltage. It’s possible to use multiple PWR units in serial or parallel connection to increase the output voltage, current, or to increase system redundancy.
