Electronic speed controllers ERV .. B for one phase motors
Electronic speed controllers ERV ..B are used to change the rotation speed by changing the supply voltage of the motor without overheating the external connection. Several motors can be controlled with one ERV.. controller if the total current does not exceed the controller's current.
ERV..B are designed with microprocessors, which help to reduce the noise emitted by the controlled motors. Additionally, all ERV..B controllers can be configured for both soft and hard starts of the controlled motor.
