Output Port Definitions: Positive (+/-) and Negative (-/). Four parallel connections are available, all with the same definition. protection function. Automatically adapts below 88V. Conveniently adjust the current. Six 1206 resistors are provided on the mainboard. Each resistor represents 80mA, for a maximum of six resistors. Fully connected output current is 480mA.
By default, with only one resistor, R13, connected, the output current is 80mA, which 't burn out the light strip. If the display is too dim, flickering, or flashing on and off, try increasing the current until the brightness is normal and the light strip is no longer hot.
The board 't burn out if no load is connected (the output voltage drop to the input voltage level if there's no load or the light strip is faulty, or even drop to the input voltage level if the load voltage is higher than 88V).
It has four output connectors, generally designated ++--. When connecting to a 2-pin light strip connector (left positive, right negative), simply connect the middle pins 2 and 3, leaving pins 1 and 4 unconnected.
