Buy Rexroth Indramat KVR Power Drive Series

Wake Industrial sells several legacy Indramat industrial automation products worldwide, including Rexroth Indramat KVR power supply modules. The power supply modules are available in varying specifications to suit the requirements of different applications.

The manufacturer’s KVR 1.3-30-3 power supply module is the most common configuration. These KVR power supply modules are used in AC drive systems to power main, and servo drives with a maximum continuous power output of 24kW. The modules can power up to ten drives at a time and are characterized by a modular construction style. They have a compact size resulting in a small footprint.

KVR power supply modules feature regenerative capability and therefore can be directly connected to a 3 x 380 to 460 V, 50 to 60 Hz mains without transformers. The energy generated during a braking action is directed to the mains once again, thereby preserving power. The Rexroth power supply modules are equipped with an internal power contactor that isolates the drives from the mains. They provide the link circuit DC voltage for the connected servo drives. These power supply modules function like inverters when they operate in generator mode. We can help you with a power supply module of the right configuration to meet your industrial manufacturing needs and even build one if needed.

• KVR power supply modules support overloading for a brief period if it is required to accelerate the main and feed drives.
• The heatsinks of these power supply modules are located outside the control cabinet in which the power supplies are installed. This results in most of the heat being generated outside the cabinets, resulting in lowering the air conditioning costs inside the cabinets.
• The power supply modules depict a drop in their power output when they are operated at higher than the intended altitudes or in humid or hot conditions.
• The KVR range of power supply modules has a two-character LED display that displays the error codes and the meanings of the error codes on their front panels based on the problem encountered during operation.
• The Rexroth power supply modules use a wire-ribbon cable to supply the signal voltage and monitor the related servo drives.

The power supply modules feature a ground rail at their top that serves as a common grounding for all the drives. They also incorporate a reset button to clear the error codes after addressing the faults. The modules are integrated with soft-start circuits to avoid high inrush current spikes and oversizing of the line connection protection devices.

KVR power supply modules support the connection of auxiliary capacitance modules. The overall continuous mechanical power output is between 25 kW and 30 kW when a 2 mF auxiliary capacitance module is used. These Rexroth power supply modules have various monitoring functions and monitor motor feedback, line voltage, load on the bleeder resistor, as well as temperature and current of the drives.
