High to low fan speed controllers for DIN rail
DRX series are electronic fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 2,5 A. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology. The motor voltage can be manually regulated via the rotary knob from maximum to minimum. This knob also has an OFF position. The minimum speed can be adjusted via an internal trimmer. The enclosure is designed for DIN rail mounting and features a green LED operating indicator.
