New design and high quality Input voltage 12V-28V; Boost ratio 1:7.5, 12V can be increased to 80V, increased from 24V to 160V. The LED lamp current is 248mA by default, which can be set to 600mA by shorting on the board. Total power is limited to 40W or less. Optimized transformer efficiency 85°C, temperature 40°C increases by 30°C. In reverse dimming mode, the ADJ dimming port is the brightest at ground and dims to off at high voltage. ADJ must not be left floating; 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 Color: Green Material: Plastic Size: 110x50mm Package Contents: 3 x Constant Current Driver Board Notice: 1. The boot has soft start and other protection, so the shutdown door must be connected to the ground when not in use. Disconnection is not recommended. 2. The dimming gate setting is 0-3V, 0V is the brightest, 2-2.5V is already very dark and basically shielded close to 3V. At this time, Output 0V) Only the above package content, other products are not included. Light shooting and different displays may cause the color of the item in the picture to differ slightly from the real item. The allowed measurement error is +/- 1-3cm.
