TVM 1.2-050-220/300-W0/115/220

The Bosch Rexroth Indramat TVM 1.2-050-220/300-W0/115/220 module from the TVM Power Supply Modules series features a Configuration 2 design and delivers a Type Current of 50 A to connected servo drives. It accepts a three-phase Input Voltage of AC 220 V and maintains a nominal Bus Voltage of DC 300 V for stable operation. The unit relies on natural convection for efficient heat dissipation and integrates directly with TCM 1 auxiliary capacitance modules to recover braking energy. Compact and robust, the module supports generator mode operation with minimal enclosure heat build-up.

The supply unit is equipped with front-panel LED displays for rapid status indication and fault diagnostics, and it automatically powers off on error to protect downstream electronics. Line protection is handled by 6.3 A fuses on each of the three-phase L1, L2, L3 terminals, while a top-mounted ground rail ensures common grounding for all connected drives. Frequency compatibility is rated at 50–60 Hz, and a dedicated RESET button clears bleeder overload conditions. Additionally, the built-in dynamic braking feature engages via a ready-state contact to safely dissipate regenerated energy.

Designed for seamless integration, the TVM unit generates the precise signal voltages required by servo drive control circuitry and handles peak return power and power return durations when the motor operates as a generator. The synchronized design mandates that both servo motor and drive remain compatible with the module’s electrical characteristics for optimal performance. Backed by a one-year Wake Industrial warranty and ready for global shipment through leading freight carriers, this power supply module is an ideal solution for high-reliability industrial automation systems.
