Triac speed controllers ERV ..T

Triac speed controllers ERV ..T are designed to change the motor rotation speed by changing voltage. Controllers have function of triac thermoprotection. The regulation of motors rotating speed is stepless from set minimum inside of controller up to full suply voltage on the controllers output. The rotating setpoint can be done with knob which is located on the cover of controller. The controllers also have ON/OFF switch with green power supply indication. Fuse is installed in the controller for safety work. More then onemotorcan be connected to the controller, if total current of all motors is less than maximum controller current.
