The car refrigerator controller adopts a self-developed high-performance MCU+ with power driver module, designed for vehicle DC compressor refrigerators. It covers C15B, C25B, C35B and more series, supports 12V/24V wide-voltage input, and delivers quiet efficiency, smart temperature control and multiple safety protections for cars, RVs, trucks and boats.

Car Refrigerator Controllers

Core Advantages

Quiet High-efficiency Compressor DriveVariable-frequency drive with vector control keeps compressor start/stop smooth and operation quiet, raising efficiency while improving cooling speed and user experience.
12-24V Wide-voltage CompatibilitySupports 12V/24V DC wide-voltage input with automatic vehicle-power detection, adapting to sedans, RVs and trucks for stable operation.
Smart Temperature Control & Energy SavingPrecise temperature algorithms with low-power design minimize fluctuation and consumption, supporting multiple cooling modes and sleep strategies to extend battery life.
Multiple Safety ProtectionsBuilt-in over-voltage, under-voltage, over-current, over-temperature and reverse-polarity protection halts automatically on fault, safeguarding compressor and vehicle battery.

About the Manufacturer

The manufacturer whose overseas expansion is supported by FangService is a high-tech company specializing in the design of motor control systems and research into complete machine systems. Founded in April 2003 with a registered capital of RMB 20.46 million, it focuses on brushless DC (BLDC) motor control systems, permanent-magnet synchronous motor (PMSM) control systems, variable-frequency systems for AC asynchronous motors, servo motor control systems, motion control systems and switched reluctance motor control systems — a technology-driven Design House that integrates R&D and design.

Over the years it has devoted itself to the R&D of variable-frequency motor-drive control algorithms and cutting-edge electromagnetic theory, building comprehensive technical strengths in FOC space-vector control, precision servo control, high-power motor drives, unmanned control systems and industrial interconnection. Together with a leading domestic semiconductor company, it has jointly developed highly integrated, cost-effective motor-dedicated control processor SOC chips (DSP / 32-bit RISC), power drive modules (IPM) and high-power IGBTs. The company runs a national-level motor laboratory and professional EMC/EMI testing laboratories, attaches great importance to quality management, and is certified to the ISO 9001 and IATF 16949 (formerly TS 16949) quality management systems.

Backed by a high-caliber R&D team and independent control and drive chip platforms, the manufacturer whose overseas expansion is supported by FangService delivers stable, reliable support across five dimensions — quality, cost, delivery, service and technology. It has been recognized as a Zhejiang Province High-Tech Enterprise, a Zhejiang Province Science and Technology SME, a Hangzhou Enterprise High-Tech R&D Center and a 2018 Gazelle Enterprise, and its motor controllers have sold more than 2.1 million units in total.

Frequently Asked Questions

Which refrigerator models use this controller?

The C15B, C25B and C35B lines cover 15–35 liter portable compressor fridges for cars, RVs, trucks and outdoor use.

How precise is the temperature control?

The controller regulates compressor speed for cooling from +20 °C down to −20 °C, with turbo-cooling mode, memory of settings after power loss and battery-voltage-aware cutoff to protect the vehicle battery.

Does it support dual zones and different modes?

Depending on the model, the platform supports dual-compartment temperature zones, ECO and MAX cooling modes, and reversible doors on select units.
