TVD power supplies are of high quality and are intended to be used for direct connection to a mains supply with 3 x 380 to 480 VAC and 50Hz to 60Hz frequency without a transformer. These power supplies are integral components of a drive system along with the drive controller and the motor. Their powerful operation allows ten servo drives to be associated with a single power supply module at a time using a bus connection.

Indramat TVD power supplies support overloading for a brief period to accelerate spindle and feed drives. These power supplies feature an internal power contactor that allows the drives to be disconnected from the mains. They communicate with the servo drives through a wire ribbon cable. Some TVD power supplies can be operated with a TBM series bleeder module. TVD power supplies are capable of operating without mains regeneration. Our industry-leading capabilities allow us to repair your broken Indramat TVD series power supplies part extremely fast.

TVD power supplies can be connected to a grounded delta or wye system without potential isolation.
The power supplies can be protected against overload by connecting them to an isolation transformer or by protecting the associated machine using an overvoltage detector. The best option is to use an isolation transformer.
The Indramat TVD range of power supplies must be operated with a commutation choke to ensure that the system perturbations are as low as possible.
Drive modules can be connected to the DC bus circuit of these drives using the bus bars provided in the connection accessories kit. Twisted single conductors are preferred for long connections of a maximum length of 1 meter.
TVD power supplies encompass two power stages for optimally matching the requirements of the application.

TVD power supplies are characterized by an IP 10 protection classification as per DIN 40 050 specifications. This means that these power supplies must be installed inside a closed housing along with the related servo drives. When one power supply is associated with multiple servo drives, the power supply must be placed near the servo drive with the highest current and power ratings. With 12 pin bus connections, 16 Indramat servo drives can be connected to a single power supply with eight drives on either side and with 16 pin bus connections, 20 servo drives can be connected. The maximum +/-15V and 20V loads must not be exceeded.

These Indramat power supplies encounter basic losses because of the generated high voltage power and signal voltages. Their replacement must be done with units of the same type and by using suitable lifting equipment after ensuring that the power to the machine is turned off. TVD power supplies are equipped with a diagnostic display featuring various LEDs to indicate their operating status.
