European Thermodynamics are pleased to announce the launch of the new JUNIOR and CyCLO pulse width modulator (PWM) thermoelectric controller electronic PCBs.

Thermoelectric Cooling Assemblies
Adaptive® Thermoelectric assemblies

Developed to work with the Adaptive® thermoelectric assemblies and thermoelectric cooler (TEC) modules, JUNIOR and CyCLO are thermoelectric controllers that enable a precise method of temperature control for sensitive engineered solutions. This, in turn, allows the solutions to work in their optimum temperature conditions.

Designed and manufactured in the UK, you can rely on JUNIOR and CyCLO to respond to user-determined limits with an alarm or visual feedback. Alternatively, you can track the temperature of the device in real time or over time to measure accurate temperature through the user-friendly Windows-based graphical user interface (GUI).

Tibor Toro, Lead Electronics Engineer said; “We have designed these thermoelectric controllers in-house, in the UK, in response to customer requirements to bring a more cost-effective and reliable product to market.”

CyCLO - ADC-48-450-UR is the simplest on/off servo controller, accurate to 1°C; now available at RS Components for £156.80 (for quantity 1).

JUNIOR - ADJ-48-450-UR is PID controlled and accurate to 0.5°C; now available to purchase at RS for £244.70 (for quantity 1).

Essential Extras
Adaptive® Peltier thermoelectric cooler (TEC) modules
Adaptive® air-to-air thermoelectric assemblies
Adaptive® direct-to-air thermoelectric assemblies
