Product Description:
The TVM 1.2-050-220/300 is a power supply module manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Within an automation cabinet, it converts the plant's single-phase AC supply into a regulated DC bus that feeds multiple drive controllers and dissipates regenerative energy through its internal bleeder circuit. The unit belongs to configuration code 2 and Series 1, and it has an IP10 housing intended for protected indoor mounting. Its insulation category C and humidity class F allow it to withstand conductive dust and moisture without electrical breakdown.
The unit accepts an input of AC 220 V at 50 to 60 Hz with a permissible variation of +15/-10 percent. From this input, it creates a stable DC 300 V bus that can be maintained within ±15 percent under load. Continuous output capacity reaches 25 A, while a short-term peak of 150 A for 300 ms covers acceleration or braking events. A type current rating of 50 A matches the module to drive axes up to 15 kW. Auxiliary rails are also provided: the 15 V monitor rail delivers 0.85 A on each branch, and the 24 V logic rail supplies 4 A with a standing wave ratio limited to 10 percent.
Total power supplied to connected inverters reaches 15 kW, and the integrated bleeder resistors can absorb 0.30 kW continuously while handling regenerated energy up to 14 kWs without external braking hardware. Safe operation is permitted at ambient temperatures up to 55 °C and at installation altitudes up to 1000 m, provided convection airflow remains unobstructed. Input voltage tolerance, internal voltage supervision, and the regulated auxiliary supply help keep the bus within drive limits, while the Series 1 control logic monitors overload, ground fault, and excessive regenerative energy before issuing a shutdown signal.
