5 step SpeedSwitch 50 (5A) – 5 step transformer with enclosure
Equipped with 5 speed positions. At minimum control signal, it is possible to set the motor to stop or run at a fixed low speed. The green lamp for operation is illuminated in the 5 speed positions, and it is flashing if the motor is not powered (though only if the “stop” function has been selected).
The phase is connected to terminal 5 when the motor is in operation. This may be used to run an auxiliary relay for activation of a heating element.
Temperature adjustment is possible by connecting a 22K NTC sensor. The control signal (0-5V, 0-10V or potentiometer) will be the set point 10-30°C. The unit is prepared for inverted operation for cold air supply.
Sensor and potentiometer to be ordered separately.
The product is being discontinued. About 19pcs. can be produced.
