Serial transistor controllers – affordable and versatile:
Serial transistor controllers provide accuracy and efficiency at an
affordable price. These products feature ON/OFF mode as stan-
dard, but can be used for proportional regulation mode (option)
when greater efficiency and temperature stability are required. In
that case, maximum power consumption is 50 W. Controllers are
available for 12 or 24 V DC and can be integrated with assemb-
lies above 50 W cooling power (except DL and LL models).
The temperature setting is fixed, but should you need to adjust
it, use the trim potentiometer on the PCB.
For battery-operated systems, low voltage protection is included.
Custom settings are available.
Available versions: BC-20, BC-21 and BE-10.
Proportional PWM controllers – for high efficiency:
PWM controllers with filtered output offer optimum efficiency
and temperature stability. The temperature is set at 5°C but can
be adjusted from 0 to 15°C.
Available for 24 V only, this compact controller is ideal for analy-
tical instruments and battery operated applications.
Low and high voltage protection, Economy mode, as well as
Automatic Cool Down™ ensure top performance for battery-
operated systems. Custom settings are available.
The controller is mainly for mounting remotely. Ask us if you
want to integrate it into an assembly.
Available versions: EC-26
Programmable controllers – with temperature display
Flexible panel mount controller for temperatures ranging from
-50°C to 90°C with display and thermometer function.
There’s one model for cooling only and a reversible model for
keeping a constant temperature when the ambient temperature
fluctuates.
You can safely wire it yourself. Apart from the desired tempera-
ture, you can also program regulation mode, hysteresis, tempera-
ture alarm, calibration and more.
Internal relays for 8 Amp continuously. The controllers operate
on either 12 or 24 V DC.
Available versions: FQ-70 and MQ-70.

Cool/Heat controllers – for outdoor cabinets:
This fully integrated controller is designed for cooling and hea-
ting outdoor electronic cabinets where accuracy is not crucial,
but reliability, simplicity and low cost are. The controller auto-
matically keeps your electronics warm in wintertime and cool in
the summer. Can handle currents up to 20 A.
A signal output indicates if the TE modules are active or not.
Available for heating below 5°C and cooling above 35°C
(LE-80), or heating below 10°C and cooling above 25°C
(LK-81). LK-81 includes low voltage protection and is designed
for temperature control of batteries and electronics.
These controllers can be integrated with the biggest AA-assemb-
lies (AA-100 to AA-200)
Available versions: LK-81 and LE-80.
PC programmable PID controller – for the most
challenging requirements:
The PR-59 controller is built for reversible control of thermo-
electric assemblies/systems with high temperature accuracy. The
controller regulates temperature (TEMs), two programmable
fan outputs and an alarm relay. The RS232 interface allows you
to read and control parameters and settings in real-time. The
controller can also be used as a stand-alone unit. Easy to use PC
programming software is included. See picture below.
Can handle loads up to 15 A, or up to 450 W in standard version.
Temperature resolution of 0.05°C is achieved with a standard
NTC sensor. Other sensors (NTC, PT) can be used as well.
Typical applications include analytical instruments, laser diodes,
thermal chambers/baths and thermocyclers.
Available versions: PR-59.
