Description

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.

Features
  • Higher shunt regulation voltage reduces power loss and improves efficiency
  • Provides option for customer to use a CT with lower VA to reduce size of the product/transformer
  • Excellent load transient performance and very sharp turn-on characteristic
  • Simple and cost-effective electrical surge-protection circuitry for a wide range of applications
