Thermoelectric coolers
3 - 25 Technical System Catalogue/Climate control
Assembly
 Installation
When installed in the enclosure, the unit only protrudes
by a few millimetres, and therefore does not interrupt
either the aesthetic appearance or freedom of move-
ment on command panels and support arm systems.
 External mounting
Its low weight also allows it to be externally mounted on
simple aluminium rear panels or blanking panels.
 Flexibility
May be mounted either horizontally or vertically.
 Ideal for command panels and support arm systems
The Thermoelectric Cooler is distinguished by its low-
vibration operation and minimal weight.
Control
 Energy-efficient control with pulse width modulation and
innovative soft start function ensures a constant enclo-
sure temperature and a long service life of the Peltier
elements and fans.
 The PID control ensures optimum activation of the Peltier
elements and fans. The speed and output are adjusted
to the ideal operating points via pulse width modulation,
and in this way ensure maximum energy efficiency.
RTC PC software
For units with heating and cooling function
 Parameter setting (including setpoints and alarm values,
heating and cooling)
 Master/slave settings
− Parallel connection of several units for additional
cooling output
− Safety circuit (redundant design)
− Interconnection of up to 5 units
− Connection via X3 unit interface
− Adaptor available as an accessory. Connetion via
RJ 45 network cable Cat 3 or above (max. 2 m)
 Monitoring (including current temperatures, fan speeds,
capacity utilisation of RTC, status display with error
messages, operating hours)
 Evaluation (recording of temperature variations,
error counters, min./max. temperatures)
 Polling and downloading of software updates
(the software is available to the units on CD-ROM,
connect using the standard USB cable supplied loose
(type A/type B))
