The Enerdoor FIN958.012.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 0/600 Vac and a rated current of 12A, with a continuous current rating of 1.5 times the nominal current. It supports output frequencies from 0 to 1000 Hz and a carrier frequency (PWM) up to 16 kHz. The device features robust electrical characteristics, including a potential test voltage of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground for 2 seconds.
Designed for demanding environments, the FIN958.012.M has an IP20 protection rating and operates within a climatic class of -40 to +85°C. Its mechanical specifications include screw terminal connections and a weight of 1.9 Kg for the .012.M model. The choke is suitable for use with high-speed motors, pumps, and woodworking machinery, particularly in closed-loop spindle motor systems.
Key features include low power loss up to 1 kHz frequency output and a 2-year warranty. The saturation current is rated at 4 times the rated current when switched on. With an MTBF of 250,000 hours at 40°C, it offers reliable performance for industrial applications.
The FIN958.012.M is rated for 600 Vac nominal operation.
The unit uses screw terminal termination with a recommended torque of 1.2 Nm.
The component operates within a climatic class of -40°C to +85°C.
The saturation current reaches 48 A during switch-on events.
Dielectric strength is 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground.
The mean time between failures is 250,000 hours at 40°C.
