Product Description

The RD52.1-4N-160-R-V1-FW is a Bosch Rexroth drive control unit, and it leverages a field-oriented regulation. Bosch Rexroth’s drive control units are designed to control and monitor electric motors. Additional sensors and actuators may need to be connected to efficiently control and monitor corresponding motors. It is a converter unit type, and its nominal connecting voltage is 3 x AC 380 V to 480 V, ± 10%. The RD52.1-4N-160-R-V1-FW weighs 157 kg, and it leverages a liquid cooling mechanism aided by an internal pump.

The size class of the RD52.1-4N-160-R-V1-FW is G, and its protection degree is IP 20. Also, its environmental class is 3K3, which translates to a recommended ambient operating temperature range of 0 – 40^o C and a 50% reduction in power at 2.5 % per Kelvin (K). It has a cooling air requirement of 0.4 m³/s and a power loss of 6.5 kW. The output frequency of this unit at a supply voltage of 380 – 480 V AC and a PWM frequency of 4 kHz is 0 – 150 Hz. It has a current rating of 290 Amperes and rated output power of 191 kVA. At T equals 60 seconds, the peak current of the RD52.1-4N-160-R-V1-FW is 377 Amperes.

Drive control units may not be used if they are exposed to conditions of operation which do not meet the ambient conditions specified. For example, it is prohibited to operate underwater and under extreme temperature variations. Only the accessories and mounted components specified in the documentation RD 500 can be paired with this drive control unit as a safety measure. Components not specified explicitly may not be attached or connected. This product can be shipped globally with a one year warranty period from Wake Industrial.
