Buy Rexroth Indramat TVR Power Supply

Wake Industrial sells several high-class refurbished Rexroth Indramat TVR power supply modules in different configurations and other industrial automation products, along with the assurance of great service and quick replacement.

TVR power supply modules have a modular structure and can be used with up to ten main and servo drives at a time. These power supply modules feature high-voltage bridges for the rectification of the three-phase mains AC and provide a regulated DC voltage to the associated drives and hence the drive dynamics are not affected by variations in the line voltage. They are equipped with DC buses to support the drives and portray regeneration capabilities with low losses when they function like generators.

TVR power supply modules are ideal for applications that feature high continuous regenerative power. These power supply modules provide power to main, and servo drives with an overall maximum continuous mechanical power output of 12 kW. The actual power regenerated by the Rexroth modules depends on the braking speed and the drive load. They can be connected to three-phase 380 VAC to 460 VAC, 50 Hz to 60 Hz power supply systems without a transformer connection. The modules are designed to be used in conjunction with several servo drives from the manufacturer, such as those of the TDM, DDS, KDA and/or TDA series.

• In many instances, TVR power supply modules can help to achieve higher drive speeds than usual because of their regulated DC bus voltage.
• The power supply modules encompass inbuilt power protection circuits to maintain the isolation of the drives from the AC power system.
• These Rexroth modules incorporate 1kW bleeding resistors that dissipate the energy regenerated by a motor braking action when the power supply is turned off, or there is a power failure.
• The Bb1 contact associated with the TVR power supply modules is a high-priority signal to operate the drive system. The internal power contactor helps to disconnect the drives from the mains and cannot be energized unless the Bb1 contact is closed.
• The effective performance of the power supply modules can be modified to the demands of the application by using TBM 1.2 series auxiliary bleeder modules when the bleeder or rotary drive rating is very high.

The bleeder resistors in the TVR power supply modules are suited for applications with small continuous regeneration requirements. The power supply module can be overloaded for a brief period to accelerate the feed as well as the main drives. They depict Class F humidity according to DIN 40 040 specifications.

The power supply modules must be free of condensates and conductive contamination on their surfaces. The Rexroth TVR modules are characterized by IP 10 degree of protection in accordance with DIN 40 050 specifications and should be installed in control cabinets.
