Product Description:
The TVM2.2-50-220/300-W1/220/380 belongs to the TVM Power Supply Modules series and serves as a regulated DC bus source for multiple drive controllers in automated machinery. It converts three-phase AC input into a stabilized internal link voltage and also provides auxiliary ±15 V and 24 V control rails for drive electronics and sensors. Its role in an industrial cabinet is to maintain consistent voltage under changing load conditions while absorbing regenerative energy that returns from braking servo axes. In multi-axis systems, this helps connected amplifiers remain stable when several axes accelerate or decelerate in close sequence.
The module operates from a line input of 220 V AC and can deliver a continuous bus current of 50 A to connected inverters. Internally, a capacitor bank maintains the DC link at 300 V DC, while ripple on the ±15 V rails is limited to 2 percent so analog circuits receive stable power. The 24 V control supply provides 8 A with allowable ripple of 10 percent for logic and sensor loads. Thermal losses can reach 580 W during normal operation, so the cabinet must provide enough ventilation to remove that heat. Clean auxiliary rails are important for low-level control and feedback circuits, where excess ripple can interfere with signal quality.
For short bursts, the bus can supply a surge of 150 A for 300 ms, allowing connected drives to handle rapid acceleration demands. The module has an available power rating of 15 kW, and its bleeder circuit can absorb up to 10 kW momentarily to limit overvoltage during deceleration. Regenerated energy is limited to 14 kWs, which is useful when several axes feed energy back into the shared supply at the same time. Despite these capabilities, the unit weighs only 15 kg, so it can be mounted in a control cabinet without special structural reinforcement. The combination of continuous output, short-term overload capacity, and braking absorption supports shared supply operation for coordinated servo axes.
