Product Description

The VMA 21KE 001-DVMA series power supply module finds its place among the various Servodyn D modules manufactured by Bosch Rexroth. This product is used with the manufacturer’s motors that are used in industrial process automation and motion control systems. The device converts three-phase AC power into DC power with high voltage. This DC power helps in the motion control of servomotors without fluctuation. It has a compact size and does not take up much space in the area where it is mounted. The unit has an input current rating of 20A and a rated voltage of 400V at 50Hz.

The connection between this power supply module and the line filter must be short. The module encompasses a line feeder and an integrated Emergency-Stop switch. The cross section of this line feeder and the cross-section of the protective earth must match with each other. The X810 and X820 connectors of the device are used to connect the signal voltage and 24V voltage supply respectively. The X312 connector is equipped with eight pins for connection. The unit is cooled by the standard air cooling method during operation.

The module features one standard variant. The product does not have any digital interface or additional function. The FGI LED of the device gets enabled internally if there is no error and the X06.7 connector has a 24V voltage rating. The DC measuring sockets of the unit must be checked before the unit is dismounted after the operation to ensure that they have zero voltage. The product can be mounted easily without any hassle and can be fitted with two power supplies so that the system can operate continuously even if one supply fails. The VMA 21KE 001-D power supply module can be shipped with a one-year warranty to any address across the globe.
