Fan speed controllers for DIN rail

DRE series are electronic fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 2,5 A. They regulate fan speed by varying the motor voltage via phase angle control - Triac technology. The power supply is 230 VAC. The minimum and maximum speed can be adjusted via Modbus RTU. The motor voltage is regulated via the 3-button keybord in the range between the selected minimum and maximum speed. Kick start or soft start acceleration can be selected via Modbus RTU. The enclosure is designed for DIN rail mounting.
