This power supply solution for Protection Relays & MCCBs handles both the current input from a Current Transformer (CT) or input from an Auxillary (Aux) source. The "self-powered" capability comes from being able to harness the power available in the grid through the CT. The flexibility of this solution's "dual-power" input comes from the ability to also handle the Aux input - which is often a battery source.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
