Product Description

The Bosch Rexroth RD52.1-8N-132-R-V1-FW/S121 is a 132 kilowatts rated drive controller. It is based on an inverter that requires 700 Volts DC input. The DC input tolerance is 10%. The inverter does not include an integrated brake chopper. The cooling method for the RD52.1-8N-132-R- V1-FW/S121 is liquid cooling with internal pump. The size class of the inverter is G. The approximate weight of the RD52.1-8N-132-R-V1-FW/S121 is 105 kilograms. According to EN 60529, the degree of protection provided by the housing of the converter is IP20. This protection rating indicates that the converter is safe from solids that have 12 millimeter dimensions. However is it not protected from solids that have smaller dimensions such as dust. The housing is also not protected from liquids. The controller can be used indoors. Improved environmental protection requires cabinet mounting.

The heat dissipated by an operating RD52.1-8N-132-R-V1-FW/S121 is 5.2 kilowatts. To prevent overheating, the controller should be separated from other heat-generating equipment. The ideal ambient temperature range is 0 to 40 degrees Celsius. The output of the controller derates between 40 and 50 degrees Celsius. Converter operation at temperatures above 50 degrees Celsius is not permitted. The RD52.1-8N-132-R-V1-FW/S121 can be operated at 4 and 8 kilohertz pulse frequencies. The rated motor output at 4 kilohertz is 132 kilowatts. The rated motor output at 8 kilohertz is 110 kilowatts. An additional function supported by the RD52.1-8N-132-R-V1-FW/S121 is standby power. This features requires an external power supply that delivers 24 Volts DC output. This controller feature is provided to ensure that the control electronics can operate in the absence of main input power. Only properly trained and qualified technical personnel should install the RD52.1-8N-132-R-V1-FW/S121 controller. This product can be shipped globally with a one year warranty period from Wake Industrial.
