Isotherm SEG00003DA – ASU Electronic Control Board for BD35F / BD50F (Ref. 001-00204)
The Isotherm SEG00003DA is a dedicated ASU (Automatic/Adaptive Start-Up) electronic control board designed for refrigeration systems using Secop/Danfoss BD35F and BD50F compressors. Serving as an OEM replacement for reference 001-00204, this module manages the core functions of ASU refrigeration, including compressor regulation, adaptive cooling logic, battery protection, and temperature control. It ensures reliable and efficient operation of Isotherm refrigerators operating in marine environments where performance and energy optimization are critical.
The board monitors available power sources, allowing the system to increase cooling output when surplus energy is present (engine running or shore power) and reduce consumption when operating solely on batteries. Built from marine-grade electronic components, the control card is resistant to humidity, salt air, vibration, and temperature variation, providing long-term reliability in harsh onboard conditions. It is intended as a direct replacement for failed or malfunctioning ASU control modules.
