REC-Precharge Module V3.1 for Dual Latching Relay Systems

New Product June 2023!

Same as the Precharge 3.0 but supports dual latching relay circuits

High input capacitance systems such as inverters, dc-dc converters, etc. can be exposed to large in-rush currents during the initial power up procedure. If appropriate measures are not employed, these currents can overly stress or even damage the system components. The pre-charge unit eliminates high in-rush currents by charging the input capacitor before the main contactor switches on, prolonging lifespan of the contactor and other components dramatically.
