Transformer single-phase speed controllers RSA5E-…M -official VENTS website

Description

APPLICATIONS
RSA5E-...-M series speed controllers are applied for air capacity control of single phase fans by means of step speed control. The controller has five speeds.	Speed is set by means of rotating the control knob at the casing front panel. 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
Casing is made of steel with polymeric coating. The controller has five speeds with the output voltage 110 V – 130 V – 160 V – 190 V – 230 V (for RSA5E- 10-M and RSA5E-13-M – 110 V – 140 V – 170 V – 190 V – 230 V).	The controller is equipped with an operation indication lamp, a speed control knob.
PROTECTION
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 for connection to the room thermostat or to the icing protection thermostat. In case of the circuit breaking the power supply to the motor is cut, except for RSA5E-10-M and RSA5E-13-M; terminals of 230 V, max. 2A/3A/4A for connection and controlling such external equipment as actuator driven air damper; provision for remote speed control (refer the connection options), except for RSA5E-10-M and RSA5E-13-M.
MOUNTING
The controller is designed for indoor mounting.	Installation shall be performed with respect to the free air circulation for inner circuit cooling.
