Usage Tips:1. LCD can input / output voltage, output current / output power / output capacity / output time;2. CNC adjustment, accurate and fast, can boost and lower voltage, output voltage can be adjusted at will of 0.5-30v, limit current 0-4a can be adjusted at will;3. Anti-reverse connection protection from input end, which will not burn;4. Anti-reverse irrigation on the output, no additional anti-reverse irrigation diode is required to charge the battery;5. Multiple software protection mechanisms are available, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be closed automatically.Input voltage: 5.0-30 vOutput voltage: 0.5-30 v Output current: can work stably at 3A for a long time, and can reach 4A under improved heat dissipationOutput power: natural heat dissipation 35 W, enhance heat dissipation 50 WVoltage screen resolution: 0.01 VCurrent display resolution: 0.001AConversion efficiency : about 88%Size:7.9*4.3*2.6cm Material:ABS+ metalColour:grayPackage Contents:1 * Power moduleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
