SnoMaster 100309 71W Compressor Controller 12V

12 V DC Control Module for SnoMaster Compressor Systems

The SnoMaster 71W compressor controller is a 12 V DC control module for SnoMaster compressor-driven cooling systems. It manages compressor start-up, speed and protection circuits. The unit interfaces with the 71 W compressor used across several SnoMaster portable fridge and freezer models.

The controller accepts a 12 V DC input and regulates the compressor through a dedicated output stage. It monitors supply voltage and current draw to prevent deep battery discharge. A three-level cut-out threshold allows users to select the protection point that matches their battery bank.

The module mounts inside the compressor compartment and connects via standard spade terminals. It operates within a 0 °C to 50 °C ambient range and draws minimal standby current when the compressor is idle. The compact footprint fits the wiring harness used on SnoMaster low-profile and single-compartment cabinets.
