396-6500 3966500 24V Voltage Load Protection Module CAT C15 C18 Excavator Engine Parts

Specification

Description

Part Number: 396-6500 (3966500), 24V Voltage Load Protection Module equipped with 4-pin standard wiring connector. Specially developed for electronic control systems of C15, C18 series excavator engines.
Integrated structure with metal sealed cylinder and temperature-resistant wiring harness, original matching specification. Precisely fits electronic control units of heavy-duty construction diesel engines. It monitors 24V circuit voltage and load fluctuation of the whole machine in real time, stabilizes power supply environment of electronic control systems, and avoids burnout faults of controllers and sensors caused by abnormal voltage. Widely applied to heavy engineering equipment such as cold planers and large excavators.

Advantage

Original matching standard, fully consistent with original parts in size, pin layout and wiring length, plug-and-play without circuit modification;
All-metal sealed housing with dustproof, waterproof and oil-proof performance, isolated from dust and muddy water on construction sites to extend service life;
Vibration-resistant integrated injection molding wiring harness, reinforced binding of red, black and white oil-resistant cables, no loose or broken wires under high-intensity bumpy operation of equipment;
Industrial wide-temperature components, stably operate without failure under extreme working conditions from -40℃ to +85℃;
Integrated multi-function circuit protection, providing four-fold protection against overvoltage, undervoltage, transient surge and overload, fully protecting the whole set of electronic control accessories;
Plug-and-play without debugging, no computer calibration required after replacement, circuit protection function recovers immediately after power-on, greatly reducing equipment downtime maintenance time.

Performance

Rated Operating Voltage: DC 24V, customized for 24V electrical systems of construction machinery. Millisecond-level voltage monitoring response to instantly capture circuit surge pulses;
Load Bearing Capacity: Matches full-power load output of C15/C18 engines, stably supports simultaneous power load of ECU, fuel injection control and sensor circuits;
Circuit Protection Performance: Cuts off abnormal circuits within milliseconds when voltage exceeds safety threshold, suppresses reverse current impact to avoid breakdown and burnout of electronic control mainboards;
Anti-interference Performance: Metal cylinder shields electromagnetic interference, isolates clutter generated by generators and large solenoid valves to ensure accurate and distortion-free transmission of sensor signals;
Durability: Original-grade wiring insulation resists corrosion of diesel and hydraulic oil. Lockable connector prevents falling off, no poor contact after millions of vibration tests;
Compatibility: Perfectly fits C15, C18 diesel engines, compatible with full series supporting equipment including cold planers, large mining excavators and pavement recyclers.
