Heavy-Duty Voltage Regulators & Alternator Control Units

If your equipment’s battery is swelling from overcharging or your dashboard electronics are flickering, a faulty replacement voltage regulator is likely the culprit. As the brain of your charging system, a precision-engineered regulator maintains a steady voltage output from the alternator, preventing costly damage to your sensitive controllers and sensors. BeeSpareParts stocks high-quality 12V and 24V regulators built to endure the extreme heat and vibration of industrial engine bays.

Charging system failures are rarely limited to one part. To ensure a reliable fix, we recommend inspecting your for internal wear, or browsing our if your battery has already been compromised. Our regulator assemblies feature advanced heat-sink designs and high-temp circuitry, offering a cost-effective alternative to expensive OEM branded components.

Whether you need a regulator for an excavator, a diesel generator, or a heavy truck, our parts are factory-tested for consistent voltage delivery and are ready for fast international shipping. Protect your electronics from power surges—upgrade to a heavy-duty voltage regulator today.
