Lenze E94AZMP0294 Mains Filter – Ensuring Stable Power Quality for Industrial Drives

The Lenze E94AZMP0294 is a robust mains filter specifically engineered for DC supply units within industrial automation systems. Manufactured by Lenze in Germany, this component plays a critical role in maintaining high power quality by filtering electrical noise and ensuring stable voltage regulation. Its design is optimized to support high-performance drive applications, helping to improve overall system reliability and efficiency.

This mains filter is rated to handle a current of 29A at 45°C and supports a voltage rating of 3 × 500V AC, operating efficiently within a frequency range of 50 to 60 Hz. It features an inductance value of 0.7 mH, which contributes to its capability to suppress electromagnetic interference and reduce voltage fluctuations that could otherwise affect sensitive drive electronics. The voltage drop across the device is minimal, at just 6.4V when operating at 29A and 50 Hz, ensuring that power loss is kept to a minimum during normal operation.

Designed with industrial environments in mind, the E94AZMP0294 includes M5 screw terminals for secure and reliable electrical connections. Proper tightening torques are specified to guarantee safe and stable installation—main screws require 3.0 Nm (26.5 lb-in), while terminal connections need to be tightened between 1.2 to 1.5 Nm (10.61-13.26 lb-in). Users should note the important safety warning that the device remains energized for up to 180 seconds after the mains voltage is disconnected, necessitating careful handling during maintenance or servicing.

By integrating the Lenze E94AZMP0294 mains filter, industrial automation systems benefit from reduced electrical noise and improved power quality, which translates into longer equipment life, fewer faults, and enhanced operational stability. Its compatibility with Lenze’s drive components makes it an essential accessory in modern drive technology setups where performance and reliability are paramount.

In summary, the Lenze E94AZMP0294 is a high-quality mains filter that delivers dependable power conditioning for DC supply units, supporting smooth and efficient operation of industrial drives and automation equipment.
