UPC1237 Class AB 2.1ch 3ch 300W x 3 High Power Speaker Protection Board Parameter:
This speaker protection board uses an integrated block specifically for the classic UPC1237 speaker protection, adding a heat sink to the relay power IC. This ensures that it adapts to higher voltages and is reliable for long term operation, low temperatures and less likely to be damaged. The IC solution is simpler than triode disk components. Reliable, power-on delay (about 3 seconds) and DC protection (output control voltage is greater than 1V) functions, LED motion indicator light, when the relay is closed. With large current relay, suitable for most power amplifier boards. Digital Amplifier is not included
Operating voltage: AC 12-15V, requires independent power supply. Suitable power: 300W * 3
Note: The grounding line of left and right channels is split and the lower sound output ground line is straight. Suitable for use with Class A and B AV power amplifiers
