Product Description:

The TVM 2.4-050-220/300-W1/115 is a power supply module produced by Bosch Rexroth Indramat for the TVM Power Supply Modules series. It converts utility power into regulated DC energy for compatible drive controllers and also provides auxiliary low-voltage rails for control electronics. Within an industrial automation cabinet, the unit feeds the DC bus, supports logic loads, and dissipates regenerative energy so connected servo axes remain stable during acceleration and braking cycles. This arrangement allows multiple connected axes to share a common supply source while the module handles line conversion and returned energy inside the cabinet.

The module accepts a single-phase input of AC 220 V at a line frequency of 50…60 Hz and tolerates line variations of +15/-10 %. Internally, it delivers a continuous output of 25 A on a DC 300 V bus, and its instantaneous peak capability reaches 60 kW; the continuous DC bus rating is 7.5 kW. A built-in blower forces air through the heat sink while power loss is held to 130 W. The 24 V supply can source 8 A, and the plus/minus 15 V rails provide 1.3 A and 1.0 A for analog circuitry. For dynamic loads, the type current is 50 A, a 0.45 kW bleeder converts excess energy into heat, and the electronics overhead is 550 VA. Configuration code 4 identifies this model, and the device can operate up to a derated ambient temperature of 55 °C without exceeding component limits.

The power section delivers 4.1 kW of mechanical energy to attached drives while maintaining thermal stability at a maximum ambient temperature of 45 °C. Operation is permitted up to 1,000 m installation altitude, and the housing meets the IP 10 protection category for enclosed-panel mounting. Up to 14 kWs of regenerative energy can be absorbed without external resistors, which helps the module manage braking energy in medium-power systems. Despite its capabilities, the unit weighs only 15 kg, and the open housing is intended for installation inside a protected cabinet rather than for direct exposure on the machine.
