NFD01.1-440-025
The Bosch Rexroth Indramat NFD01.1-440-025 is a high-performance module in the NFD Mains Filters series, designed to optimize power line quality in advanced industrial drives. This mains filter is identified by Line 01 and engineered for a nominal voltage of AC 115 to 440 V, supporting a wide input range. Rated for a continuous 25 A load, the unit delivers reliable suppression of unwanted noise and interference. Compact and robust, this filter integrates seamlessly into existing control systems and complies with stringent industry standards for electromagnetic compatibility.
Featuring cutting-edge technical capabilities, the NFD01.1-440-025 accepts a three-phase AC 440 V input at 50/60 Hz frequency, ensuring universal compatibility with global power grids. Its EMC compliance is certified to reduce both conducted and radiated emissions, while filtering out interrupting radio-frequency interference. The module operates with exceptional stability under a rated current of 25 A, maintaining low insertion loss across the specified voltage range. Designed for seamless integration, it interfaces directly with the power source and downstream equipment such as transformers and contactors to safeguard sensitive electronics.
Operational features of this mains filter include a temperature range of 0 to +40°C, ensuring consistent performance in standard industrial environments. The filter tolerates a relative humidity of up to 90% (non-condensing), while the natural convection cooling method eliminates the need for additional fans or auxiliary cooling systems. Certified for a maximum altitude of 1000 meters, it maintains its suppression characteristics without derating, even at elevated installation sites. Installation guidelines recommend mounting the unit within a control cabinet, with provision for an air passage gap to facilitate adequate ventilation and prevent heat accumulation.
Integration of the NFD01.1-440-025 into drive packages and frequency converters is straightforward, owing to its compact design and standardized mounting footprint. It can be installed alongside frequency converter modules, providing a unified solution for power conditioning and drive control. When grouped in multi-filter configurations, spacing recommendations ensure optimal ventilation and accessibility for maintenance. Backed by a one-year product replacement warranty, this filter is ideal for applications in motion control systems, automation lines, and other environments where stable, clean power is essential.
