The pre-charge unit is a device that gently charges the input capacitors of inverters and other capacitive loads before the main contactor switches on. It eliminates the brutal high inrush currents at the switch-on of the contactor and prolongs the contactor lifespan dramatically.
- Low power consumption
- Integrated 66ohm power resistor
- 2 A contactor coil drive
- Fixed 4 s delay version
- Reverse polarity protection
- Over-voltage protection
- Suitable for 12, 24 and 48 V systems (11-68 V DC)
