KVR 1.2-30-3/S380

The Bosch Rexroth Indramat KVR 1.2-30-3/S380 power supply module from the KVR Power Supply Modules series offers a robust solution for industrial DC bus applications. With a continuous rated power of 30 kW and a circuit voltage of 320 V, this module delivers reliable energy conversion for demanding environments. Featuring voltage outputs of 24 V, it can simultaneously supply up to ten main and servo drives, making it ideal for comprehensive drive systems. Designed for primary function as a high-performance DC bus power converter, it integrates seamlessly with modular AC drives to ensure stable operation and precise power delivery.

Incorporating advanced technical specifications, the KVR 1.2-30-3/S380 includes a DC bus continuous power rating of 30 kW and a maximum regenerative power of 100 kW via its integrated DC bus choke. The unit supports critical functions such as soft-start, phase monitoring, internal line protection, and dynamic braking, all monitored through a comprehensive suite of built-in diagnostics. Communication with attached drives is achieved via a ribbon cable interface, while dedicated connections for bridge capacitance and the GLD18 DC bus choke or KD24 commutation choke are located at the front panel alongside AC line input and common grounding rails.

Constructed for durability and efficiency, this power supply module is designed for back-panel enclosure installation, minimizing heat loss to just 20% of total dissipation. It supports direct connection to three-phase power systems rated 380–460 VAC at 50/60 Hz without an external transformer. An integrated soft-start circuit prevents inrush current spikes, and the enclosure layout ensures optimal cooling. The KVR 1.2-30-3/S380 also comes with a one-year warranty, and its modular design and global shipping capability guarantee fast deployment and simplified maintenance in diverse industrial applications.
