Description: Features: brand new and high quality Power input voltage 12V-28V; boost ratio 1:7.5, 12V can be increased to 80V, 24V boost to 160V. LED lamp current defaults to 248mA, which can be adjusted to 600mA through short on the board. The total power output is limited to 40W or less. Optimized working efficiency of transformer efficiency 85C, 40C temperature rise 30C. In the reverse dimming mode, ADJ is the dimming port, the grounding is the brightest, and the high voltage is dimmed to the extinction. ADJ is not allowed to hang, if it is not connected, it will be connected directly to the floor. Notice:1. the boot has a soft start and another for protection, so the blackout door should be connected to the floor when not in use. It is not recommended to be disconnected. 2. the blackout door setting is 0 3 3 v , 0 v is the brightest, 2 2.5 v is already very dark, and is basically protected close to 3 v. At this point, output 0 v) According to the flag on the board, connect vcc, gnd, en (enable), dimming adj, a total of four input ports, the output selects the positive and negative output ports of the LED.
