Product Description:

The TVM 2.4-050-220/300-W1 is a power supply module from Bosch Rexroth Indramat in the TVM Power Supply Modules series. It converts plant AC input into a regulated 300 V DC bus that can feed multiple servo drives from a common source. This arrangement supports coordinated motion in automated production cells and reduces the need for separate supply sections on each axis. The module also combines rectification, energy recovery, and auxiliary 24 V control power in a single housing, which helps simplify cabinet layout for industrial automation. Because several axes can share the same DC link, the supply centralizes power conversion instead of duplicating it in each connected drive.

The module accepts AC 220 V input at 50–60 Hz and tolerates line variations of +15/-10%, while the DC bus can vary by ±15% without tripping. Its rectifier provides 7.5 kW of continuous bus power and can absorb short peaks up to 60 kW during acceleration or regenerative events. Continuous output current is rated at 25 A, and type code 050 indicates a 50 A line current capability. Configuration code 4 with version 2 identifies the connection arrangement used with Indramat drive racks. The internal electronics draw 550 VA, a 0.45 kW bleeder resistor dissipates excess voltage, and the built-in blower supports stable operation under the stated input conditions.

At full load, the design dissipates only 130 W of heat and can operate in ambient temperatures up to 55 °C. The supply can absorb as much as 14 kWs of regenerated energy on the DC bus, which helps manage returned energy from connected axes without an external braking resistor. Its logic rail can source up to 8 A for sensors, contactors, and related control devices, allowing the module to support common low-voltage cabinet functions. The unit has an IP10 enclosure, weighs 15 kg, and is intended for cabinet installation below 1000 m without derating, with surrounding airflow needed to carry heat away from the module.
