TRANSFORMER SPEED CONTROLLER
J
Single phase speed controller
Applications
RSA5E-2-P series speed controller is applied for air
RSA5Е-2-P
capacity control of single phase fans by means of step
control of motor speed. 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.
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 thermostat for the icing protection. In case
of the circuit breaking the power supply to the motor
is disabled;
terminals of 230 V, max. 2A for connection and
controlling such external equipment actuator driven

air damper;
Design
The controller casing is made of flame-retardant
provision for remote speed control (refer the
thermoplastic. The controller has five speeds with
the output power 110V-130V-160V-190V-230V
and incorporates ON/OFF button with pilot light, the
control knob for speed switching and the 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.
connection options).
J
Mounting
The controller is designed for indoor mounting.
Installation shall be performed with respect to the free
air recirculation for inner circuit cooling.
Speed control enables not only selecting the
comfortable ventilation mode for the periodically
visited premises but reducing the energy consumption
for the ventilation.
