DN1221 –熱電冷卻器控制器THERMOPTICS品牌原裝正品

原廠料號(hào)：DN1221品牌：THERMOPTICS

The DN1221 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

ed resistor. Temperature stability of 0.01°C is

achieved by the linear PI control loop of the DN1221.

Proportional gainintegrator time constant are set

independently with resistors. No external integrator

capacitor is needed. These parameters can be optimized to

minimize temperature overshootstability. In addition,

the maximum coolingheating current supplied to the

TEC can be adjusted independently from 0 to 2.2 amperes

with two resistors.

An evaluation kit is available that contains the DN1221, a

fan cooled TEC,an aluminum cold plate (with

imbedded thermistor) that is attached to the TEC. The

evaluation kit operates on a 12 VDC power supply.

Temperature of the cold plate can be changed from 0 to 60

°C with a variable resistor. The TEC is mounted on a

socket so that it can be easily removed.
