Product Description

TVM 2.4-050-220/300-W/115/220 is a power supply module. It is manufactured by Bosch Rexroth. The module is part of the TVM series of units designed specifically for demanding applications. The power module’s main function is conversion of AC input to DC output. The AC to DC conversion is performed by a rectifier on the power module. The module supplies DC output to connected drive units. Rated output of the TVM 2.4-050-220/300-W/115/220 module is 50 Amps. The input voltage rating is 220 Volts AC (three-phase). Control electronics on the unit require AC input at 115 Volts or 220 Volts AC. The module’s DC bus carries nominal 300 Volts DC. Specified ambient conditions allow module operation as per manufacturer specifications. Bosch recommends 5 to 45 degrees Celsius temperature and 0 to 1000 meters altitude for module operation. Beyond these specified limits, the output of the module derates i.e. falls below rated values. Bosch permits derated operation of TVM modules at temperatures between 45 and 55 degrees Celsius, and at altitudes between 1000 and 5000 meters. The optimal storage temperature is -30 to 85 degrees Celsius. Several accessories are available for TVM modules, including dynamic braking resistors, auxiliary capacitors, autotransformers, and isolation transformers. Autotransfomers are used to match the AC supply voltage to the input rating of the TVM module. Isolation transformers are used to protect the TVM module when it is getting supply from an ungrounded AC mains. Bleeder modules are used to increase the regenerated power of the power module. The product documentation contains relevant instructions related to module operation and safety. Operators and staff must follow these instructions for reliable and safe operation of TVM power supply modules.
