The Enerdoor FINHRM5C.090.M-60 is a passive harmonic filter engineered to mitigate harmonic distortion in electrical systems. It operates at a nominal voltage of up to 480 Vac and handles a rated current of 90A, with a frequency range of 50-60 Hz.
This filter ensures compliance with IEEE519 and EN61000-3-12 standards, reducing current Total Harmonic Distortion (THD) to less than 5%, even with unbalanced voltages up to 2.5%. It features low power loss and a compact, open-frame design. The filter is suitable for applications involving VFDs, servo drives, industrial automation, HVAC systems, and end-user facilities.
Key technical specifications include a potential test voltage of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground. It offers overload capability of 4x rated current upon switch-on and operates within a climatic class of -40 to +85°C. The MTBF at 40°C is rated at 250,000 hours. Typical power loss at 400 Vac is 530W and at 480 Vac is 636W.
The nominal operating voltage is up to 480 Vac.
The rated current is 90A.
The frequency range is 50 – 60 Hz.
It reduces current THD to less than 5%.
The operating temperature range is -40 to +85° C.
The MTBF at 40°C is 250,000 hours.
