Product Overview

This Automotive Electronic Module is an AC-to-DC power conversion unit for onboard electrical equipment. It is used in vehicle refrigeration, compressor-control assemblies, auxiliary equipment, and other vehicle systems that require a dedicated DC supply from an AC source.

Key Advantages

30 V DC Output with ±0.5 V Accuracy

The output remains between 29.5 and 30.5 V across the specified input range. During compressor start-up or changing load demand, the controlled output prevents wide voltage drift that can delay cooling or interrupt the connected controller.

Ripple Below 50 mV

Low output ripple limits electrical noise reaching radios, sensors, and control circuits installed near the converter. This is especially useful when the module shares a vehicle enclosure with audio or signal-level electronics.

Compact 44 x 46 x 21.8 mm Package

The module fits into narrow equipment housings and refrigerated cabinet control compartments. It operates from -20°C to +60°C and can be stored from -30°C to +85°C, covering vehicle interior and auxiliary equipment environments.

Customization Capabilities

Electrical Ratings
Input window, target DC output, output current, ripple target, start-up behavior, and protection thresholds can be designed around the compressor, controller, or auxiliary load.

Connector and Mounting Interface
Pin definition, connector family, wire length, mounting holes, fixing method, cable direction, and enclosure dimensions can be matched to the equipment layout.

Filtering and Housing
Filter components, noise-control requirements, PA+GF housing geometry, color, and molded identification can be developed for the installation and thermal conditions.

Quality Control

First-Piece Electrical Approval
Approved samples and first pieces are checked for connector definition, enclosure dimensions, assembly condition, and no-load output before continuous production begins.

Load Start-Up and Stability Test
Representative compressor loads are started repeatedly, and the module is checked for output recovery and uninterrupted operation. No-load and loaded results are compared with the approved sample before release.

Mechanical and Final Release
Validation units are dropped from 1 m onto concrete and then inspected for housing cracks, loose components, connector movement, and electrical restart. Production parts receive final appearance, marking, and assembly checks before packing.
