Product Description:
TVM1.2-50-220/300-W1-115/220 is a Bosch Rexroth power supply module. It is part of the TVM product line. Bosch's AC drive system is comprised of one supply module and multiple drive modules. Several drives units can be run from one TVM supply module. The TVM module is a component of Bosch’s modular AC drive system. TVM modules provide the high voltage DC for the motor power and the control voltages for connected Bosch drives. A power rectifier on the TVM module rectifies the three-phase mains AC voltage and provides the high voltage DC for the drive units. When the drives are in generator mode, the regenerated power is absorbed by an optional bleeder resistor. Buffer capacitance is used to provide sufficient smoothing. The TVM module supplies the electronics of the connected drive module via the wire ribbon cable. TVM modules are equipped with extensive monitoring functions. The modules communicate with the drives through the signal bus voltage. Input voltage rating of the TVM1.2-50-220/300-W1-115/220 module is 220 Volts AC (three-phase, 50 to 60 Hertz). The output DC voltage is 300 Volts DC. The nominal output of the module is 50 Amps. Control electronics on the unit operate at single-phase 115 or 220 Volts AC input. An internal blower is used for heat dissipation. The cool air entering from the inlet at the bottom of the module is forced output via the air outlet at the top. The ambient temperature range recommended by Bosch is 5 to 45 degrees Celsius. Weight of the TVM1.2-50-220/300-W1-115/220 module is 15 kilograms. It is designed for vertical mounting. At least 80 millimeter spacing must be provided on the top and bottom sides for good ventilation.
Frequently Asked Questions about TVM1.2-50-220/300-W1-115/220:
Q: When is a bleeder resistor required?
A: A bleeder resistor is required to increase the regenerated power.
Q: When is an autotransformer required?
A: Autotransformers are used to match the AC supply to the TVM input rating.
Q: When is an isolation transformer required?
A: Isolation transformers are used for isolation when connecting TVM modules to ungrounded AC mains.
Q: What is the mounting orientation?
A: Mounting orientation of the module is vertical.
Q: What is the insulation class of the module?
A: Insulation class of the module is C.
