Acrylic Gla outer shell, beautiful design and generous, key touch texture is good, pre the on to set the output voltage, eliminating the need to a . The on can control the output to turn off and on, and can set the product power-on default is ON or OFF. LCD can display input and output voltage, output current, output power. Input re polarity protection, re connection will not 2. High efficiency over 93%, large current, small heat, output voltage 1.2-32V arbiry regulation, constant current value of about 0-4.5A adjustment, suitable for office power, high-power LED constant current drive, battery charging and so on!3. There are two ons on the left side of the module: IN/OUT, ON/OFF: IN/OUT on to switch the input voltage and output voltage display, pre to switch the output current and output power display; ON/OFF on control output ON or OFF, pre to set the time the default output state is ON or OFF.4. The right side of the module has two ons: '+' and '-'. Pre the '+' on to increase the output voltage by 0.05V. Pre and hold it to increase it continuously. Pre and hold it again for a continuous slow step increase of 0.1V and 1V. '-' on, the output voltage is reduced by 0.05V, pre can continue to reduce, and then pre to reduce the step by 0.1V and 1V.5. Input voltage: 6.5-36V (input voltage le than 6.5V, current is not accurate, le than 5.5V, LCD display is not normal); Output voltage: 1.2-32V, factory default output 5V. Output current: Can work stably at 3.5A for a time, and can reach about 4.5A under enhanced heat diation (adjustable limit current is about 4.2-4.5A); Output power: natural heat diation 50W (le than 3.5A), enhanced heat diation 75WVoltage display: resolution 0.05V, range 1.2-32V, accuracy ofabout ± 0.1V (accuracy demanding carefully shot!)Current display: resolution 0.005A, range 0-4.5A, accuracy ±0.05A (precision for those who require strict accuracy!)Conversion efficiency: about 94%Working current: about 30mARe input protection: YesAnti-backflow at the output end: None (If the battery is charged, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; if the condition is required, connect the anti-backup to the positive side of the output string)Short circuit protection: YesSize: length x width x height 70.5 x 48.4 x 28mmWeight: 62gModel Number:ZK-J5XCurrent Type:DCcolor:Photo colorMaterial:plasticPackage Contents:1 x DC BuConverterOnly the above package content, other products are not included.Note: Light reflection and different displays may ca the color of the item in the picture a little different from the real thing.
