1. Plexiglass outer shell, beautiful and generous, key touch texture is good, press the button to set the output voltage, eliminating the need to use a knife. The button 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 reverse polarity protection, reverse connection will not burn 2. High efficiency over 93%, current, small heat, output voltage 1.2-32V arbitrary regulation, constant current value of about 0-4.5A adjustment, suitable for office power, high-power LED constant current drive, lithium battery charging and so on 3. There are two buttons on the left side of the module: IN/OUT, ON/OFF: IN/OUT button to switch the input voltage and output voltage display, long press to switch the output current and output power display; ON/OFF button control output ON or OFF, Long press to set time the default output state is ON or OFF. 4. The right side of the module has two buttons: '+' and '-'. Press the '+' button to increase the output voltage by 0.05V. Press and hold it to increase it continuously. Press and hold it again for a continuous slow step increase of 0.1V and 1V. '-' button, the output voltage is reduced by 0.05V, long press can continue to reduce, and then long press to reduce by 0.1V and 1V. 5. Input voltage: 6.5-36V (input voltage less than 6.5V, current is not accurate, less than 5.5V, LCD display is not normal); Output voltage: 1.2-32V, default output 5V. Output current: Can work stably at 3.5A for a long time, and can reach about 4.5A under enhanced heat dissipation (adjustable limit current is about 4.2-4.5A); Output power: natural heat dissipation 50W (less than 3.5A), enhanced heat dissipation 75W Voltage 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 accuracy ) Conversion efficiency: about 94% Working current: about 30mA Reverse input protection: Yes Anti-backflow at the output end: None (If the battery is , on the module and then connect the battery, and that the battery voltage is lower than the output voltage; if the condition is required, connect the anti- diode to the positive side of the output string) Short circuit protection: Yes Size: length x width x height 70.5 x 48.4 x 28mm Weight: 62g Model Number:-J5X Current Type:DC color:Photo color Material:plastic Package Contents: 1 x DC Converter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
