ON-BOARD CHARGER

OBC 22K

Compact and efficient high-voltage charging up to 850 Volt

The REFUdrive OBC 22K On-board Charger is designed to provide efficient and reliable charging with a maximum voltage of up to 850 volts. Thanks to its state-of-the-art SiC switching technology, the device ensures high efficiency and performance even under harsh environmental conditions. The water-cooled design includes galvanic insulation for safe operation of the charger. In addition, it can operate in a wide range of ambient temperatures, making it suitable for any climate and environment.

FLEXIBLY SCALABLE AND CONFIGURABLE

Depending on your needs, the On-board Charger can be configured and connected in different ways. In pair mode, two units can be used sharing a 63 A/400VAC input, allowing operation with an AC wallbox in accordance with the EN 61851-1:2011 standard. For higher charging power, up to 8 units can be connected in parallel to increase scalability.
