求翻译:With the Single-coil variant of the EVC 250, current reduction is provided by an external circuit outside of the relay in the controller electronics. For example, a pulse width modulation (PWM) technique can be applied to reduce the effective coil current to a holding value after the first 100 ms of uninterrupted suppl是什么意思?![]() ![]() With the Single-coil variant of the EVC 250, current reduction is provided by an external circuit outside of the relay in the controller electronics.
