Temperature based motor control
These are transformer fan speed controllers with temperature input. They control the motor in function of the measured temperature. The temperature setpoint can be adjusted via the potentiometer. The fan speed can be manually selected via the rotary switch – 5 different speed selections. In automatic mode, fan speed is adjusted in function of the measured temperature. The controllers up to 7,5 A have a plastic enclosure. The controllers above 7,5 A have a metal enclosure.
