Enerdoor motor protection reduces harmful dV/dt generated by variable frequency drives imposed onto the motor. Motor protection devices are designed to work in various applications of switching frequencies and frequency outputs.

The Enerdoor sine wave filters FIN905SF and FIN915SFH reduce the PWM effect, converts the PWM to a sine wave and eliminates dV/dt. These lines work with applications in open or closed-loop feedback. This series carries CE and UL approvals and offers a current range from 3 to 1000A.
