AOS has developed a range of high
performance, low cost controllers for thermoelectric (Peltier)
cooling applications. Capable of temperature control to better than
±0.005șC and of providing drive currents of up to 3A (bipolar,
heat/cool) these circuits can usually be operated without the need
for external heatsinking.
The PC1 controller is a very small (65mm x 40mm) OEM unit, offering
proportional (P) and proportional-integral (PI) control. In normal
operation it uses a 10k ohm (nom) NTC thermistor as the temperature
sense input although operation with other NTC thermistors is
possible. The PC1 controller operates from a single +5 volt rail and
has been designed primarily as a high quality set-point controller
for the telecommunications and optical sensing industry sectors
although other application areas may benefit from its excellent
thermal and electrical performance.

In addition to an identical performance to the PC1 the PC2 series of
controllers has a number of enhanced operational features.
-
Numerous sensor capability (Pt100,
Pt100, 10k, 2k2 and other NTC thermistors, AD59X and LM335 sensors
-
P, PI and PID controller
functionality
-
Reverse and over voltage supply
protection
-
Run-away temperature detection and
shutdown circuitry
-
