RPCS 730 inverter
The range for the compact needs.

The RPCS 730 series combines inverter, double inverter and combi inverter in the power classes from 15 - 250 kW. The innovative water cooling of the inverter and dual inverter in a single housing makes it suitable for installation in very compact drive systems without control cabinets. Thanks to its robustness, high shock and vibration resistance, it can also be used under harsh conditions. The series also offers a flexible and individual configuration for optimum interaction and meets the requirements up to protection class IP6K9K.

One series - innumerable possibilities
