Product Description

TVM 2.1-50-220/300-WI-220/380 is a power supply module. It is produced by Bosch Rexroth. The module belongs to the TVM product line. TVM supplies convert AC input to DC output. The output can be delivered to multiple drive units. The module provides DC high voltage for motor power and control voltages for connected drives. Input rating of the module is 220 Volts AC. The module supports three-phase input. An autotransformer can be used to adapt the input when connecting to AC mains with a different supply voltage. Bosch permits module connection to grounded AC mains. Connection to ungrounded AC mains is permitted when an isolation transformer is used to protect the power supply module. Nominal output of the TVM 2.1-50-220/300-WI-220/380 module is 50 Amps. Supply voltage for the control electronics is 220/380 Volts AC. It has an IP10 rated enclosure. A built-in blower helps to improve heat dissipation. The recommended ambient temperature is 5 to 45 degrees Celsius. Output of the supply derates linearly at temperatures between 45 and 55 degrees Celsius. Bosch does not permit operation at temperatures higher than 55 degrees Celsius. The recommended site elevation range is 0 to 1000 meters. Output of the module derates non-linearly between 1000 and 5000 meters. Bosch does not permit module operation at elevations higher than 5000 meters. A bleeder module is available as an accessory for increasing regenerated power. Capacitors and dynamic braking resistors are also available as accessories. Standard autotransformers are available in floor-mount or wall-mount configurations in power ranges up to 20 kVA. Standard isolation transformers are available in floor-mount or wall-mount configurations in power range up to 10 kVA. Trained personnel should operate the supply module
