Rectifier / Voltage Regulator – For ATV Buyang FA-D300 / FA-H300 (No. 5.3.01.0081)

⚡ Rectifier / Voltage Regulator – For ATV Buyang FA-D300 / FA-H300 (No. 5.3.01.0081)

Aluminum Alloy Voltage Converter for Buyang, Feishen & Xingyue ATVs

This Rectifier / Voltage Regulator is a central component in the electrical charging system of your Buyang FA-D300, FA-H300 as well as many Feishen and Xingyue ATV models. It converts the alternating current (AC) generated by the alternator into the direct current (DC) required by the battery and limits the voltage to the correct charging level ($\sim 14 \text{V}$).

The casing is made of an Aluminum Alloy, which ensures improved heat dissipation. The regulator corresponds to the manufacturer part number 5.3.01.0081.

Note on Voltage Specification ("2 Volt"): The regulation is for a $12 \text{V}$ on-board network; the specification "2 Volt" likely refers to an internal circuit value or is an error in the source description. The correct $12 \text{V}$ regulation is the relevant functional detail.

✅ Product Features & Specifications:

• Item Type: Rectifier / Voltage Regulator.
