Product Description

All Bosch Rexroth products are designed with the aim to promote the efficient and cost-saving operation of various kinds of machinery. The company’s RD 43 series of power inverters are a perfect reflection of their commitment to developing futuristic drive control devices. These power inverters are manufactured solely for the RD 500 SFT 160 kW inverter and serve as forward and reverse feed units in the system. The RD43.1-4R-185-R-NN-FW/S132 is one of the power inverters that make up this series, and it can easily be wired with other modules in the cabinet for space-saving installation.

The RD43.1-4R-185-R-NN-FW/S132 is a power inverter variant without a brake chopper. The supply voltage for its operation is a 3-phase AC supply that ranges from 380 V to 480 V with a ± 10 % allowance. At a three-phase AC supply voltage of 400 V, its DC-link nominal power rating is 185kW. Heat dissipation is enhanced in the product, with its cooling being achieved using liquid cooling with an internal pump. At a pulse frequency of 4.2 kHz, the rated line current of the RD43.1-4R-185-R-NN-FW/S132 is 250 A. Its rated (line) peak current values are 353 A and 461 A for 60 seconds and 1 second, respectively.

The Bosch Rexroth RD43.1-4R-185-R-NN-FW/S132 power inverter weighs 157 kg, and it is designated an IP rating of IP 20. Hence, it is protected against solid objects above 12 mm, like fingers. The optimum ambient conditions for its operation are a maximum ambient temperature of 40 ^oC and relative humidity not more than 90 %. It should be noted that this product exudes heat; hence, it should be operated at a suitable distance from heat-sensitive devices and units. This product can be shipped globally with a one year warranty period from Wake Industrial.
