The EDC is designed to be controlled from a DC current source or voltage source. Pulse width modulation
(PWM) is not required. If a PWM signal is used to carry frequency greater than 200 Hz, do not use a pulse
current of more than 120% of that required for full output.
Control signal requirements
Recommended PWM signal is 200 Hz, avoid exceeding 440 Hz.
