and high quality Power input voltage 12V-28V; Boost ratio 1: 7.5, 12V can be increased to 80V, increased from 24V to 160V. The LED lamp current defaults to 248mA, which can be set to 600mA via short on the board. Total output power is limited to 40W or less. Optimized operating efficiency of transformer efficiency 85 ° C, temperature of 40 ° C increases 30 ° C. In reverse dimming mode, ADJ is the dimming port, ground is brightest, and high voltage is dimmed to extinction. ADJ is not allowed to hang, if not connected, it will connect directly to the ground. According to the flag on the board, connect vcc, gnd, in (activation), adj dimming, a total of four input ports, the output selects the positive and negative output ports of the LED. Specification: Model: CA-6019 Input voltage: 10-28V Output voltage: 5-165V colour: green Material: plastic size: 110x50mm Package Contents: 3 x Constant Current Driver Board Notice: 1. The boot has a soft start and other protection, so the shutdown door must be connected to the floor when not in use. Disconnection is not recommended. 2. the opaque gate setting is 0 3 v, 0 v is the brightest, 2 2.5 v is already very dark and basically shielded near 3 v. At this point, Output 0 v) Only the above package content, other products are not included. Note: Light shooting 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.
