Product Description

TVM 2.2-050-220/300-W1/220/300 is a Bosch Rexroth TVM series power supply module. Its input rating is 220 Volts AC. The module requires three-phase input at 50/60 Hertz. Nominal current output of the module is 50 Amps. The nominal DC bus voltage is 300 Volts DC. Control electronics on the TVM 2.2-050-220/300-W1/220/300 module require single-phase input at 200/300 Volts AC. The module features an internal blower. This blower increases airflow across the module to improve heat dissipation. Bosch recommends 5 to 45 degrees Celsius ambient temperature. Module operation outside this range leads to output derating and can also lead to malfunction. Bosch recommends 0 to 1000 meters site elevation for rated operation. Module operation outside this range leads to derating and can lead to malfunction and/or failure. The TVM 2.2-050-220/300-W1/220/300 module has an IP10 rated housing. This housing is not protected against dust and moisture ingress. Therefore, even though the supply can be used indoors, it can only be used outdoors when installed inside a suitable industrial cabinet. Proper spacing around the module is necessary for ensuring smooth airflow, which is mandatory for keeping ambient temperature within specified limits. The mounting orientation of the supply module is vertical. The power terminals are located on the front side of the unit. A 25 Amps DC power fuse is also installed at the front of the unit. A reset switch is also located on the front of the power module. Operators can connect a bleeder module on the output side to increase the regenerated power. Other available accessories include capacitors and dynamic braking resistors. The product documentation lists relevant operation and safety instructions that must be followed for safe and reliable operation.
