Audio Module Single DC 12V to ± 24V Subwoofer Car Audio 1. With isolation function, the power board test conditions input DC12V, the ±12V output is about 13-14V without load, 2. The ±18V output is about 19V when no load is applied, and decrease a bit after being loaded. 3. The power amplifier circuit has a certain voltage adaptability range, it doesn' matter how high or low it is, a few volts. 4. If installed in a car, the actual working voltage of the car is about 13.5V, and the output be higher. 5. This board does not have a voltage stabilizing open-loop circuit, has small ripple, good transient response, high efficiency and low heat generation, and is suitable for power amplifiers. Description: 1.Output power: 200W 2. Input voltage: DC10-15V 3. Output current: 200W/output voltage = output current. That is, the higher the output voltage, the smaller the current. Specifications: ± 24V output Colour:As Shown Material:PCB Size:75x70x36mm Package Contents: 1x Power Amplifier Module 1x 10A Fuse Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
