TVM 2.1-050-W1/220/380V

TVM 2.1-050-W1/220/380V, Bosch Rexroth Indramat, TVM Power Supply Modules. The TVM 2.1-050-W1/220/380V unit from Bosch Rexroth Indramat in the TVM Power Supply Modules series delivers a robust DC bus feed for Indramat AC drive systems. Featuring a Configuration of 1 and a nominal Type Current of 50 A, it converts three-phase mains into stable DC for multiple drive channels. The three-phase Input Voltage requirement of AC 220 V spans an Operating Voltage Range from 198 to 253 V AC at an Input Line Frequency of 50…60 Hz. Built to industrial standards, this module ensures precise power rectification and continuous operation under varying line conditions.

In detail, the TVM module produces a Bus Voltage of DC 300 V with a tolerance of ±15%, while the control electronics receive 380 V AC single-phase via a dedicated input. The built-in blower cooling provides efficient heat dissipation, maintaining performance across an Ambient Temperature Range of 5 to 45 °C. Should temperatures rise toward 55 °C, the output will derate by up to 20%, protecting downstream drives. Packaged in an IP10 housing, it meets indoor protection requirements and simplifies installation within dust-proof, water-resistant cabinets. These specifications enable seamless integration with ribbon-cable control outputs at 15 V and 24 V levels and safeguard against overvoltage or overtemperature events.

Reliable and service-friendly, the TVM 2.1-050-W1/220/380V features front-accessible field wiring and a discharge path to safely bleed the DC bus during maintenance. Its standardized footprint and connection scheme allow straightforward upgrades or expansions in multi-axis drive arrays. Ideal for packaging, material-handling, and CNC applications, this power supply module underpins high-precision motion with consistent, fault-tolerant DC power.
