ELECTRONIC SPEED REGULATOR FOR SINGLE-PHASE MOTORS 230V 3.0A

ERV ..B electronic speed regulators for single-phase motors
The ERV ..B electronic speed regulators are used to vary the rotation speed by varying the power supply
motor voltage without overheating the external connection.
It is possible to control multiple motors with one ERV..B controller if the total current does not exceed
the controller current.
Mounting: surface or built-in version. ERV 4.0B – surface only.
Control type: potentiometer.
Infinitely variable speed control.
ON/OFF switch installed in the potentiometer.
Protection: Fast acting fuse.
Minimum speed setpoint within the controller. The hard start time setpoint within the file
ticket inspector. The start from the maximum rotation speed with the time delay to set one with a
potentiometer. If the setpoint is 0, the controller will start in soft mode – minimum a
maximum.
Overheat protection is active if the temperature inside the controller reaches 65°C. Then
the controller output gradually decreases until the temperature decreases. If the temperature
increases further and reaches 75°C, the regulator switches off and on again only when the
the temperature drops to 55°C.
The switching on of the regulator is signaled by the lighting of the setpoint knob.
