Product Description:
The TVM 1.2-050-220/300-W1/220/380V is a power supply module manufactured by Bosch Rexroth Indramat within the TVM Power Supply Modules series. Installed in drive cabinets, it converts the plant's three-phase mains into a regulated DC link and distributes that energy to multiple servo drives. It also absorbs regenerated power through its integrated bleeder circuit, so individual drives do not need separate rectifier stages. This arrangement supports coordinated motion axes in industrial automation cells and centralizes the cabinet power stage for several connected drives.
The unit accepts an AC 220 V line with a permissible deviation of +15 / -10 % and operates on a 50–60 Hz network. Internally, it produces a DC 300 V bus and supplies a continuous rated output of 25 A at the terminals. Momentary load peaks are covered by a 150 A surge capability, while overall throughput is limited to 15 kW. The type current is 50 A for configuration code 2 devices in Series 1. Control electronics are fed from 230 V or 400 V auxiliaries, and a built-in blower removes the 550 W worst-case heat loss; its 30 W fan operates from a dedicated 220 V supply. This current reserve helps the module support acceleration events and other short-term demand spikes on the shared DC link.
The bleeder stage can dissipate 0.30 kW continuously and can reach 10 kW during short braking spikes, with total absorption limited to 14 kWs. The enclosure has an IP10 rating, so the module is intended for installation in closed control cabinets below a mounting altitude of 1000 m. Operation is permitted at ambient temperatures up to 55 °C, and the 220/380 V auxiliary tap allows an input-voltage tolerance of +10 / -15 %. The integrated bleeder handles returned energy from decelerating axes instead of letting that energy accumulate on the DC bus. The assembly weighs 15 kg, with the fan power, cooling ducting, and wiring contained inside one enclosure.
