AC fan speed controller 0-10 V EVSS-1100-DM

 Variable speed controller with analogue input. It controls single-phase motors with a maximum current of 10 A. The motor can be activated or deactivated via the integrated ON-OFF switch or remotely via the digital input. High and low speed are adjustable via internal trimmers. The analogue input type can be selected via jumpers or via Modbus RTU (0-10 V or 0-20 mA). Kick start or soft start acceleration and different operating modes are selectable via Modbus RTU. The supply voltage is 230 VAC. The unregulated output is active when the motor is enabled. The AC fan speed is regulated by varying the motor voltage via phase angle control - Triac technology.
