Product Description

The RD51.1-4B-200-R-M1-FW/S139 drive control manufactured by Bosch Rexroth operates as a converter without a built-in chopper. The control has a supply voltage of 3 x 380 to 480VAC with a tolerance of +/-10%. This product must be setup at an elevation of 1,000m above sea level for rated performance. The device is associated with a G size class. The unit is integrated with a heat exchanger and a line filter. It features liquid cooling mode with an internal pump. This control encompasses a frequency converter with a frequency of more than 150Hz and no output choke. The product must always be installed only in the vertical orientation.

The device requires an external fan transformer to provide the required power to the inbuilt fans. The unit must encompass sufficient antifreeze and corrosion control. It has to be ascertained that there is no deposit in the cooling tubes. The control comes with an output frequency ranging between 0Hz and 150Hz. The coolant circulation system of the product has a maximum system pressure of less than 1 bar. This device may have live control and power terminals even when the motor is in standstill mode. The unit is likely to get damaged if it has an incorrect supply voltage. This drive control can be dispatched globally with a one-year warranty tag from Wake Industrial.

The control must incorporate bolted busbars between the main contactors of the converter and the line filter. Its motor and power supply connection terminals have a cable cross-section of 70mm² to 240mm². This product comes with a peak power of 299kVA for one minute when the pulse frequency is 4kHz. The device comes with a direct connection between the protective earth and reference ground through the cable connection to its housing. The unit may have high electrical voltage because of wrong connections. It should not be put into operation if the application does not adhere to the national EMC regulations.
