AUTOMATIC SPEED CONTROL: The Kooltronic Fan and Blower Automatic Speed
Control (Part Number KSC100) is a solid state "smart" controller packaged in a
NEMA 1 type enclosure for remote mounting. The allowable input power supply
range is 95 to 250 Volts, 47 to 63 Hz. It is furnished standard with an IEC 320
connector, a power supply fuse and a temperature sensor. Additional temperature
sensors are optional.
Power Cord is not provided.
The controller will operate single or multiple fans or blowers of compatible
voltage and frequency up to a combined load of 6 Amps. The controller may be
operated by either a control voltage signal of 0 to 10 VDC, a control current
signal of 0 to 20 mA or one to three temperature sensors. With multiple
temperature sensors the controller will respond to the highest sensed
The control circuit board is furnished with a terminal strip for field
connecting the sensor and fan wires. A pressure type strain relief connector is
furnished in the enclosure. If required by the installation or by code, this
connector can be replaced with a 1/2-inch [12.7mm] trade size conduit connector.
A wide variety of control logic options can be field programmed into the
controller by means of a board mounted DIP switch. These include fan idle or
starting speed at 30%, 40%, 50% or 60% of supply voltage, fan on or off below
the idle setting, control temperature setting of 86ºF (30ºC), 95ºF (35ºC), 104ºF
(40ºC), 113ºF (45ºC), and temperature differential settings of 7ºF (4ºC) and
18ºF (10ºC). The selectable fan on/off feature is operative when the
temperature(s) drop below the control temperature setting.
Consult factory for use with compatible Kooltronic fans or blowers.
