TVD Power Supply
Rexroth has been producing some of the world’s best motion control technology for decades, and we specialize in service and support for Rexroth drives, controls, servo motors, and power supply modules. The TVD Power Supply module provides a regulated DC bus circuit voltage for the power feed to Rexroth drives.
As many as 10 drive modules can be served by a single TVD Power Supply module.
This power supply can be connected directly to the mains without a transformer, assuming the voltage is 3 x 380V. If the voltage is higher or lower, transformers can be used along with the direct connection. Ungrounded three-phase mains supplies may also require the use of a transformer.
The TVD does not feed regenerated power back to the mains, but it can keep your machinery going during brief power outages or interruptions.
Your TVD module will have a code number, such as one of these:
Obviously, your power supply module is essential to keep your machines running. These modules are not designed for troubleshooting or repair on the machine. The modular design allows you to pull the unit out and replace it, minimizing downtime.
With a legacy part, factory repair is a viable option — Rexroth supports most legacy units from the 20th century — but you need to get it done right and fast. We can provide emergency replacement units and offer factory repair and reman with fast turnaround.
Remember, Rexroth doesn’t provide original parts to third party repair shops. Sending your power supply module to a third party increases downtime and delays resolution of your problem. Factory repair brings your unit back to your facility in like-new condition with a new factory warranty.
