    RSA5E-…T series speed controllers are applied for air capacity control of single phase fans by means of motor step speed control. The controllers have five speeds. Speed is set by means of rotating the control knob at the casing front panel to one of five available fixed positions. Several fans can be controlled synchronously in case their total consumption current does not exceed the maximum permissible value of the controller current.

    Design and control

    The controller casing is made of flame-retardant thermoplastic. The controller has five speeds with the output power 80V - 105V - 130V -160V - 230V and incorporates ON/OFF pilot light for operation indication, control knob for speed switching and controller emergency operation LED indicator. The integral motor protection device is included which cuts the supply voltage to the fan if the thermal contact in the fan motor is activated. After the temperature drops to the operating level the motor restarts.

    The controller has the following supplementary functions:

    • terminals of 230 V, max. 2A for connection and controlling such external equipment as actuator driven air dampers.

    The controller is designed for indoor mounting. Installation shall be performed with respect to the free air recirculation for inner circuit cooling .The controller is for vertical installation. Do not install the controller above the heaters and in bad air convection areas.
