Fan motor speed controllers
Fan motor speed controllers for AC and EC type fans. All controllers are marked with CE marking and conform to EU and CIS regulations.
TGRV - for single phase motors, 5-step controller
Meant to control single phase fan motors, these 5-step transformer controllers change the motor speed by changing voltage. Equipped with power supply protection.
5 fixed steps: 230V / 170V / 140V / 120V / 80V
Maximum ambient temperature: +40°C.
LED voltage indication.
Additional connection 230V/50Hz ~1 0.5A.
If thermal protection is triggered, the controller needs to be switched off and on again.
