Feature: The two yellow lines are the AC input, the white line is the DC positive output, and the aluminum housing is the negative output. The input AC voltage range is: 15-55V, and the output DC voltage is 13.5V. This regulator is a thyristor device that charges the battery at a constant voltage, with a thyristor half-controlled bridge. The structure is simple and the installation is very convenient. Effectively protect the circuit of the generator from safe operation and stability. Specification: Input voltage: 15 - 55V AC Output voltage: 13.5 0.5V DC Output current: 8A-10A Working temperature: -5 C - 65 C Storage temperature: -20 C - 90 C Dimensions: 75mmx61mmx28mm (LxWxH) Suitable for: Permanent magnet flywheel generator Working voltage: 14V (battery) Weight: 170g Package list: 1 x Diesel Generator Voltage Regulator Note: The actual product color may deviate from the photo due to light.
