The Enerdoor FIN958.090.M is a high-frequency differential choke engineered for motor protection applications. It provides excellent attenuation to reduce dV/dt, safeguarding motors from voltage spikes.
This choke operates with a nominal voltage of 0 to 600 Vac and supports output frequencies from 0 to 1000 Hz. It has a rated current of 90A and a carrier frequency (PWM) range of 0 to 16 kHz. The device is built to withstand potential test voltages of 2400 Vdc (phase to phase) and 3200 Vdc (phase to ground) for 2 seconds.
With an IP20 protection rating and a climatic class of -40 to +85°C, the FIN958.090.M is suitable for demanding environments. It features terminal block connectors for easy integration and offers low power loss up to 1 kHz frequency output. The choke is designed for use with motors, high-speed pumps, woodworking machinery, and spindle motors in closed-loop systems.
Key specifications include a saturation current of 4 times the rated current and a continuous current rating of 1.5 times the nominal current. It also boasts a Mean Time Between Failures (MTBF) of 250,000 hours at 40°C and comes with a 2-year warranty.
