Specification: Condition: 100percent Brand New Item Type: LED Boost Board Model: 12ES Material: Printed Circuit Board Color: As Pictures Shown Input Voltage: 10-20V Output Voltage: 15V-88V Suitable for 15-24 Inch Universal LCD LED Quantity: 4PCS Weight: Approx. 94g LED inverter board modified problem: 1. Connect power supply, ground wire and switch signals required by boost board to universal LED boost board VCC power supply ON switch signal ADJ brightness control GND ground wire Prompt: Connection method same as LCD inverter board 2. Use multimeter to measure out how many lines the LED light connecting line power supply is, What are the negative poles and what are the lines Line more is just positive and negative points, should do not use technology, see the light bar can see the definition. Prompt: The power supply of LED lights is the same. They are all connected together. The number of negative electrodes represents the number of series electricity CN1: power supply, power supply, switch signal, brightness control, ground wire, ground wire . Package List: 4 x LED Boost Board Note: Connection of LED must noted that the interface definition is just positive pole and negative pole, the positive pole input power supply must not be connected backwards or wrong, improper connection caused by the consequences.
