The temperature controller for the climate systems based on Peltier modules
The controller is designed for reversing (Heating /
cooling) control one or two thermoelectric
assembly. The two thermistors KTY81-110 which
are present in the incoming package are used as
the temperature sensors for measuring the
temperature inside the cabinet – Tin and the
outside temperature - Tout

FACTORY SETTINGS
Turning on the cooling mode is carried out at the T2 temperature (25˚C), the heating mode at the T1
temperature (15˚C). Another possible factory setting of T1, T2 is in the temperature range -50 + 70 ° C.
The controller manages thermoelectric air-to-air assemblies used as the climate system for:
- Outdoor cabinets
- Thermostats for various applications
- Cold rooms and showcases
- Rack Management
- Cabinets with electronic equipment
- Other.
Specifications.
- DC management in the modes ON / OFF
- Changing of voltage polarity supplied to the thermoelectric modules during the change-over from the
cooling mode to the heating mode
- In case of 2 assemblies, both assemblies operate synchronously
- Operating DC voltage - 18 – 58V
- Maximum current of each output pair to modules - 7 A at a voltage 58V.
- Maximum current of outputs to the fans - 1A at a voltage 58V.
- The controller operating depending on temperature measured by two thermistors A1 (internal) and A2
(external)
- Protection against break or short-circuit of thermistor A1 (shut off the output voltage of the controller).
Break or short-circuit of thermistor A2 are ignored.
- The length of the connecting wires of thermistors are 1000 mm and 500 mm.
- The minimum temperature measured by the thermistor -55˚S
- The maximum temperature measured by the thermistor + 150˚S
- Another possible factory setting of T1, T2 is in the temperature range -50 + 70 ° C. T1 is smaller than
T2 at least on 2 degrees.
