New Product – EV Power Smart Precharger

Going back to our roots as a specialist electronics manufacturer we pleased to introduce the new Smart Precharger.

DC Motor controllers and Inverters typically have large internal capacitors on their input. They require inrush protection when first powering up to prevent a large current spike which can damage contactors , switches or blow fuses.

The EV Power Smart Precharger offers a soft start for DC controllers and inverters, limiting the inrush current via a resistive circuit to charge up the internal capacitors before automatically closing the main contactor. It can also detect faults and safely discontinue precharge if it fails to start correctly. Common faults are usually due to an external wiring fault, no battery voltage or the precharge fails to complete within a few seconds due to unexpected DC loads.
