Wide voltage input: 17V–65V Output voltage: 12V Output current: 10A Power: 120W 1. Wiring method Input end: Red wire connects to the positive terminal of the power source. Black wire connects to the negative terminal of the power source. Output end: Yellow wire connects to the positive terminal of the load. Black wire connects to the negative terminal of the load. 2. Precautions a. This step-down converter does not feature reverse polarity protection. Always verify correct polarity connections for both input and output before wiring to prevent damage. b. Ensure the input voltage and power are sufficient to support the connected output device. c. The load device must be rated for 12V operation, and its power requirement must not exceed the converter’s maximum output capacity (120W). Accessory styles and colors may vary by batch, but functionality remains unaffected.
