- RSA5D-…M series speed controllers are applied for air capacity control of three-phase fans by means of step control of motor speed.
- 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 130 V – 180 V – 230 V – 300 V – 400 V and incorporates control speed knob, light indication for operation.
- The controller has built-in motor overheating protection which cuts power supply in case of exceeding the set temperature threshold.
- After the temperature drops to the operating level the motor restarts.
- As an additional function, the controller has terminals (230 V, max. 2 A) for connecting external equipment (e.g. air damper actuators).
