RND01.1-5-007

RND01.1-5-007, Bosch Rexroth Indramat, RND Three Phase Mains Chokes opens with a robust design to ensure clean power delivery into demanding inverter applications. This 7 kW choke features a Design 1 construction that integrates seamlessly with industrial power trains. Its compact footprint belies a substantial mass of 125 kg, providing mechanical stability and low vibration under load. Manufactured to Rexroth’s exacting standards, the module is essential for the proper operation of compatible power inverters.

The choke accepts a Max. Mains Connecting Voltage of 3 x AC 380 – 480 V, ± 10% and handles a continuous current of 300 A without derating. Built-in IP00 protection mandates installation in a suitably rated enclosure, while its 3K3 environmental class construction withstands dust and contaminants in harsh factory atmospheres. Airflow requirements of 1000 m³/h ensure adequate cooling, allowing operation across an ambient temperature range of 0 … 40 °C and up to 90% relative humidity. Despite high energy throughput, the choke limits internal dissipation to a rated power loss of 2.5 kW for predictable thermal management.

Engineered for integration into Rexroth Indramat drive systems, the RND01.1-5-007 delivers low harmonic distortion and smooth current waveforms to downstream inverters. Its rugged build and proven performance enhance system reliability, reducing unscheduled downtime and maintenance. When paired with RD series power inverters, this mains choke optimizes boost converter operation and extends component life in high-demand industrial applications.
