  • 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.
  • 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.
