The Bosch Rexroth Indramat produced 1070083179 (VMA 21KE 001-D) VMA series power supply module is part of the Servodyn D range. This compact unit is designed for use in industrial process automation and motion control systems, converting three-phase AC into a high-voltage, fluctuation-free DC power for precise servomotor operation. This module demands an input current of 20A and boasts a rated voltage of 400V at 50Hz. The device is equipped with a line feeder, an integrated Emergency-Stop switch, and several specific connectors, each assigned for connecting different types of voltage supplies. Despite its compact size, the 1070083179 (VMA 21KE 001-D) VMA series model ensures operational safety by requiring a short connection between the power supply module and line filter. It also has similar cross-sections for the line feeder and protective earth to prevent mishaps. Cooling is efficiently managed via standard air cooling methods during operation. One notable feature is the module's FGI LED, which confirms the absence of errors when internally enabled. For safety, a voltage check is recommended on the DC measuring sockets before dismounting the module. Provisions are made for parallel hookup of two power supplies to ensure uninterrupted operation, even in the event of a single supply failure.
