Product Description:
The TVM 2.1-050-220/300-W1/115/220V is a power supply module produced by Bosch Rexroth Indramat within the TVM Power Supply Modules series. It conditions mains energy for the DC bus that feeds Indramat drive controllers and dissipates regenerated power through an integrated bleeder circuit. Classified under product group Power Supply Module, the device follows configuration code 1 in series 2 and is housed in an IP10 enclosure that uses a built-in blower to move cooling air through the chassis.
The module accepts an input of AC 220 V at 50–60 Hz and keeps operation stable within a +15/-10 % line variation; the supply is converted into a DC 300 V bus that holds the required energy for several drive axes. Under continuous duty the supply can deliver 25 A, while short acceleration bursts are supported by a 150 A peak for 300 ms. These output capabilities align with the type designation that rates the unit for 15 kW of apparent power and a type current of 50 A. Internally, the conversion process draws up to 580 W of power loss, and the blower section uses 30 W of ventilation power to evacuate that heat. The accepted mains frequency range permits installation worldwide.
Environmental and energy-handling limits round out the performance profile. The module withstands operation up to an altitude of 1000 m and a maximum ambient temperature of 55 °C before thermal derating begins. Its bleeder resistor can dissipate 0.45 kW continuously and reaches 10 kW for regenerative peaks, accepting up to 14 kWs of returned energy from the drives. Control electronics are powered by either 115 V AC or 220 V AC supplies that observe a ±10 % tolerance. A built-in blower moves air through the housing, and total assembled mass is 15 kg, enabling cabinet installation without special lifting equipment.
