KVR01.3-30-3/S380

KVR01.3-30-3/S380, Bosch Rexroth Indramat, KVR Power Supply Modules. The KVR01.3-30-3/S380 from Bosch Rexroth Indramat is part of the KVR Power Supply Modules series, designed to deliver robust power support in demanding industrial environments. This module provides a 320 V circuit bus and converts incoming three-phase AC into a stable DC link, while also supplying a 24 V control voltage to connected servo drives. With a continuous 30 kW power rating, the supply module can briefly peak at higher outputs to accommodate rapid acceleration demands. Integrated regeneration capability captures braking energy and redirects it back into the DC link, minimizing waste heat and improving overall system efficiency.

Designed for high availability, the module operates over a 50–60 Hz mains frequency range and sustains a peak link power of 90 kW during regenerative events. A built-in bleeder power of 40 kW resistor safely dissipates excess energy in emergency stops, while internal loss management limits cabinet heat to 170 W under full load. The supply electronics and DC link are protected by a three-phase rectifier and a heavy-duty bleeder resistor, ensuring secure energy routing. Mechanical design keeps weight to 31 kg for the main unit, plus 4.2 kg for the auxiliary fan assembly, facilitating rack-mount installation and straightforward service access.

This supply module seamlessly integrates into multi-axis drive systems, offering plug-and-play compatibility with Bosch Rexroth’s drive controllers and braking resistors. Its regeneration function and compact footprint boost system uptime and simplify cabinet layout, while rugged construction underpins dependable operation. Ideal for high-speed machine tools, material handling installations, and complex automation cells, the KVR01.3-30-3/S380 ensures precise power delivery and safe energy recovery in advanced AC drive networks.
