Product Description:
The TVM 2.2-50-220/300-W1 115/220V is a power supply module built by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Designed for use in multi-axis drive systems, the unit converts AC mains into a stabilized DC link and auxiliary low-voltage rails so that servo amplifiers receive consistent energy under dynamic load conditions in industrial automation. By centralizing power conversion in one module, it supports coordinated operation across several connected axes and helps keep the supply structure compact. This arrangement allows connected drive components to share a common energy source instead of relying on separate supplies for each axis.
It accepts a nominal line of 220 V and can draw a rated current of 50 A while delivering up to 15 kW of continuous power to the DC bus. The bus is held at 300 V, and short-term load peaks are supported by a 300 ms surge capability of 150 A. For control electronics, the module furnishes a 24 V logic rail rated at 8 A and a +15 V sensor rail that can source 1.3 A. Dynamic braking energy is routed into an internal bleeder network that can dissipate 450 W continuously and tolerates a peak of 10 kW. Configuration code 2 and series index 2 identify the component size and connector layout. Internal ventilation consumes 30 W, and the IP10 housing provides basic touch protection.
During regenerative operation, the bleeder can absorb feedback energy up to 14 kWs before the drive system must intervene. Under worst-case conduction and switching losses, the assembly releases 580 W of heat, so the cabinet must provide adequate airflow. Continuous ratings apply up to a mounting altitude of 1000 m and an ambient temperature of 55 °C; above these limits, derating is required. The 15 kg enclosure is intended for upright control-cabinet mounting and relies on forced-air paths established by the internal fan. The module is intended for enclosure installation where directed airflow can remove heat from the power section during continuous operation.
