SRED – red electronic thermostat module for 12V and 24V compressor refrigerators

SRED is an electronic control module for compressor refrigerators, designed for selected cooling systems based on Secop / Danfoss 101N series compressor controllers. It can be used in selected vehicle refrigerators, marine refrigerators and other mobile cooling systems.

It is a Plug & Play solution, designed to be installed in place of the standard module without the need for any modifications to the electrical system. SRED offers more configuration options and better control of refrigerator operating parameters than standard mechanical solutions.

Main features of the SRED module

• - Temperature adjustment in the range of -5 to 12°C
• - Compressor speed adjustment
• - Adjustable voltage cut-off threshold
• - Parameter configuration using small DIP switches located directly on the PCB
• - Tilt sensor support with the option to disable it
• - No 23-hour operating limit – works continuously
• - Plug & Play installation without modifications to the wiring

Power supply

The SRED module operates within a wide input voltage range of 9–32V DC, which allows it to be used in both 12V and 24V systems.

Application

The module is intended for selected vehicle refrigerators and cooling systems based on Secop / Danfoss 101N0 series compressor controllers.
