Product Description:
The TVM 1.1-50-300-W1 power supply module is manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Installed in a drive cabinet, it converts the plant’s AC mains into regulated DC link energy for connected servo hardware. It also provides auxiliary logic voltages for Indramat servo amplifiers used in automated machining, packaging, and assembly equipment, so the module supports both the power stage and the control electronics in the same drive system.
This module is fed from a nominal input of 220 V and raises that voltage to a link-circuit level of 300 V DC for the shared drive bus. With a typical throughput capability of 15 kW, it can supply a steady output current of 50 A while tolerating short bursts up to 150 A for 300 ms during acceleration peaks. Internal dissipation is limited to 550 W, and configuration code 1 indicates the standard rack format used across the series. Operation is permitted up to 1000 m mounting altitude, and ambient temperature can reach 55 °C without derating. The module also provides a ±15 V rail with a 2% standing-wave ratio and a 24 V logic rail rated at 4 A with a 10% standing-wave ratio, while 30 W is reserved for forced-air ventilation of the enclosure.
During deceleration and load rejection, the bleeder network absorbs regenerated energy that returns from the driven axes, handling 450 W continuously and up to 10 kW for brief intervals. Its thermal capacity allows a maximum feedback of 14 kWs before duty-cycle limits are reached. The unit has a mass of 15 kg, which adds mechanical stability and supports heat dissipation from internal components. Maximum power loss figures allow cabinet ventilation to be sized with predictable margins when repeated motion cycles produce sustained heat.
