DN1220 Description
The DN1220 is a subminiature Bipolar Temperature Controller for Thermoelectric Coolers (TEC) used in fixed temperature OEM applications. The device is designed to operate with a Negative Temperature Coefficient (NTC) thermistor that senses the temperature of the object attached to the TEC. Temperature is set with a user selected resistor.
