The June 2023 product, similar to Precharge 3.0, supports dual latching relay circuits, effectively mitigating in-rush currents in high capacitance systems like inverters by pre-charging input capacitors. This protection extends component life. Features include a robust design, low power consumption, adjustable delay settings, and up to 120 V, 4.0 A pre-charge, with integrated power resistors and over-current protection. It also offers reverse polarity and over-voltage protection

New Product June 2023!

Same as the Precharge 3.0 but supports second latching relay circuit.  See manual for details.

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.
