Overview
The Rexroth R911307937 (HNF01.1A-F240-E0051-A-480-NNNN) is a main line mains filter from Bosch Rexroth’s HNF series, engineered for IndraDrive motion control systems. This filter operates at a nominal current of 51 amperes and a line voltage of 480 volts. The Rexroth R911307937 is designed to suppress electromagnetic emissions and prevent line capacitance leakage in three-phase AC power distribution for industrial drive systems.
Key Features
- Specialized design to meet Electromagnetic Compatibility (EMC) standards and effectively mitigate leakage from line capacitance, acting as a suppressor against potentially disruptive emissions.
- Built in line with stringent safety measures of application F 240.
- Easily adjustable with assigned factory power units for performance optimization.
- EMC-area per DIN 61800-4 of A with Degree of Protection of A.
- Three-phase input and output, 50–60 Hz operation.
- Compact, industrial-grade construction for DIN-rail mounting systems.
Technical Specifications
Input: 3x AC 400–480V ±10%; 51A; 50–60 Hz ±2. Output: 3x AC 400–480V ±10%; 51A; 50–60 Hz ±2. Operating temperature: 40°C. Weight: 39 lbs. Dimensions: 19″ × 10.5″ × 5″.
