on order, occasionally in stock Series PEC Peltier Controller 300W
PEC Peltier Controller 300W


The PEC-300 combines a high-end-PID-controller, a branded switching power supply and a PWM module in a sturdy aluminium desk top case. The connectors are mounted on the back side of the unit.

  • Large setting range: -30/+800°C
  • PWM operating at 12,5kHz, no hazard for the peltier modules
  • Depending on the sensortype accuracy <1K and resolution <0,1K
  • Self optimizing PID-controller
  • Standard units for 12V and 15V power output available, other voltages per request
  • Interface RS485 built in, USB-RS232-converter (PEC-OPT03) is available
  • Delivered with a sensor Pt100

This series was designed in Austria and is built here completely. Customer specific requirements can be implemented quickly, also with small production costs.

The PID-control unit is the KS41-1 made by PMA, the following documents are ready for download here:

Attention - important note:  in the manual, a process "Download Firmware" is described this process must be carried out only with a certain combination of PC hardware / operating system. Please Never start this process, it can lead to total functional failure of the controller, which can be resolved only in the supplying plant. All Controller PR-59 were and are supplied by us with the current firmware, there currently is no need for a renewed download.

on order, occasionally in stock Series SR-54 Peltier Controller
SR-54 Peltier Controller


The TC-XX-SR-54 is a temperature controller on a microcontroller base, which is installed in thermoelectric units, as an addition to the existing temperature control. The TC-XX-SR-54 is a bipolar temperature controller with precise control accuracy that can be used for cooling and for heating of thermoelectric devices. It has 3 programmable outputs, alarm relays and alarm LED´s. The parameters are preset at the factory according to customer specifications (standard thermostat). Special solutions are possible but may require a certain minimum order quantity.

  • Input Voltage 16 ... 60 VDC (no built-in power supply!)
  • PWM clocked at 8 kHz, no lifetime limitation for Peltier Modules
  • Control range: -20°C ... +100°C with standard-NTC, other areas possible depending on sensor
  • Cooling and heating
  • Temperatur sensor: NTC, other sensors possible
  • USB-Interfacee
  • free programmable
