R911729433
The R911729433 (TVM 2.1-050-W1-115) is a TVM series power supply module made by Bosch Rexroth Indramat, designed to provide direct current (DC) voltage to Indramat drives along with control voltages. It operates on 220 Volts alternating current (AC) input in three-phase format, which is rectified to generate high DC voltages for the drives. The module can power up to six Indramat drives and may need an autotransformer to align the mains AC input with the module's input. To protect the input end of the power supply, a circuit breaker or fuse can be utilized. Additionally, the supply requires a separate 115 Volts AC input, in single-phase format, to supply the drives with 15/24 Volts DC control voltages.
The R911729433 (TVM 2.1-050-W1-115) has an output current rating of 50 Amps and a DC bus rating of 300 Volts DC. It has a continuous power rating of 7.5 kilowatts, with a maximum power rating of 60 kilowatts. The module includes a built-in blower for cooling. Its recommended operational temperature range is between 41 to 113 degrees Fahrenheit, and it should be stored or transported within an ambient temperature range of -22 to 185 degrees Fahrenheit. It has an IP 10 protection rating and should be housed in an industrial cabinet to shield it from dust and moisture.
