Product Description:
TVM 2.1-50-220/300 is a power supply module. It belongs to Bosch Rexroth’s TVM product line. The module is designed for 220 Volts AC input. It works with three-phase supply systems. When connecting to AC mains with a different rating, an autotransformer can be used to match the supply to the module’s input rating. Rated output of the module is 50 Amps. Rated output is possible when the input voltage is 220 Volts AC, the ambient temperature is between 0 and 45 degrees Celsius, and the site altitude is between 0 and 1000 meters. The output derates when the ambient temperature or the site altitude is outside these specified limits. Derated operation is permitted, but is not recommended. For derated operation, the upper limit for ambient temperature is 55 degrees Celsius. For derated operation, the upper limit for site altitude is 5000 meters. A built-in blower on the TVM 2.1-50-220/300 supply module improves heat dissipation and helps to keep ambient temperature within specified limits. Proper spacing around the installed module is also necessary for smooth airflow and maintenance of ambient temperature. Bosch has designed the TVM 2.1-50-220/300 module for vertical mounting. It has an IP10 rated housing. The module is suited to indoor use. For outdoor use, it must be installed inside a cabinet the provides adequate environmental protection. Humidity class of the unit is F and the insulation class is C. Several accessories are available for separate order. Autotransformers and isolation transformers are available in wall-mount and foot-mount configuration. Bleeder resistors are available for increasing the continuous and peak regenerated power. Only trained personnel with proper qualifications should be allowed to install and operate the power module.
Frequently Asked Questions about TVM 2.1-50-220/300:
Q: How can operators increase average and peak regenerated power?
A: Operators can use a bleeder resistor to increase regenerated power.
Q: Is the module suited to outdoor use?
A: With an IP10 rated housing, the module can be used outdoors when housed inside a suitable cabinet.
Q: Does the module require single-phase or three-phase input?
A: The module requires three-phase input.
Q: How can operators match the input rating to the AC supply?
A: An autotransformer can be used to match the AC supply to the input rating of the module.
Q: How can operators protect the module when using ungrounded AC mains?
A: Operators can use an isolation transformer when connecting the module to ungrounded AC mains.
