SDX-DM
ELECTRONIC FAN SPEED
CONTROLLER
PRODUCT DESCRIPTION
The SDX-DM series are electronic fan speed controllers, which allow you to manually
adjust the rotational speed of single phase AC motors by varying the motor voltage
through phase angle control. The output can be regulated from minimum to maximum
or from maximum to minimum. The operating mode can be selected via Modbus
RTU. The controller is suitable for both inset (IP44) and surface mounting (IP54). All
parameters and settings can be adjusted via Modbus RTU communication.
