KOOLTRONIC, INC., of Pennington, NJ, the leading manufacturer of air
conditioners, heat exchangers, fans
and blowers for electronic enclosures, announces the introduction
of its new Fan
and Blower Speed Controller.
Fan and Blower Speed Control, Model 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.
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 temperature.
The control circuit board is furnished with a terminal strip for 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 ½ inch 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.
In the 60th year of service to its customers, Kooltronic is the leading manufacturer
of air conditioners, heat exchangers, fans and blowers designed specifically to
