• RM1307731648976083 note! ! ! Delivery with accessories, you must personal assembly; module for the DC / DC Buck module, can not enter the transformer immediately step down the AC power; to price the battery, ensure that the module output first power after which join the battery, the battery is full, first pull Battery, the last module strength off, to prevent the battery voltage backflow (preferably at the output of the module is attached to a enormous recent diode can prevent backflow) 1 Product Highlights 1 Plexiglass outer shell, exquisite design and generous, key touch texture is good, press the button to set the output voltage, getting rid of the necessity to use a knife; 1 The button can management the output to show off and on, and can set the product power-on default is ON or OFF; 1 LCD can display enter and output voltage, output current, output power; 1 Input opposite polarity protection, opposite connection won't burn; 1 High performance over 93%, wide current, small heat, output voltage 1 arbitrary regulation, fixed recent value of about 0-4 adjustment, appropriate for workplace power, high-power LED fixed current drive, lithium battery charging and so on! 2 Product parameters Input voltage: 6 (input voltage lower than 6, recent is not accurate, less than 5, LCD reveal isn't always normal) Output voltage: 1, manufacturing facility default output 5V Output current: Can paintings stably at 3 for a long time, and can reach about four beneath enhanced warmth dissipation (adjustable limit current is set 4) Output power: pure warmth dissipation 50W (less than 3), enhanced heat dissipation 75W Voltage display: decision 0, differ 1, accuracy of about ± 0 (accuracy aggravating intently shot!) Current display: decision 0, fluctuate 0-4, accuracy ±0 (precision for those that require strict accuracy!) Conversion efficiency: about 94% Working current: about 30mA Reverse input protection: Yes Anti-backflow at the output end: None (If the battery is charged, first strength on the module after which join the battery, and make sure that the battery voltage is less than the output voltage; if the situation is required, join the anti-backup diode to the fine side of the output string) Short circuit protection: Yes Size: size * width * top 70*48*28mm Weight: 62g 3 Function description three There are two buttons at the left aspect of the module: IN/OUT, ON/OFF: IN/OUT button to change the enter voltage and output voltage display, lengthy press to change the output current and output energy display; ON/OFF button control output ON or OFF, Long press to set a better time the default output state is ON or OFF The right side of the module has two buttons: '+' and '-' Press the '+' button to increase the output voltage by way of 0 Press and hold it to increase it continuously Press and maintain it again for a continuous gradual step develop of zero and 1V '-' button, the output voltage is decreased via 0, lengthy press can continue to reduce, and then lengthy press to minimize the step by 0 and 1V three ADJ-I is a current setting potentiometer, clockwise rotation, can increase the set current, when the weight recent reaches the set current, enter the fixed recent state, CC constant latest indicator (red) lighting up The ON indicator is the output status indicator It is on when the output has a voltage, in any other case it's off The CHAR indicator is the charging indicator When charging, it's on The FULL indicator is full If the set constant latest value is 2A, the charging When the present reaches zero or less, turn on the lamp, the FULL lamp is on, and the CHAR lamp is off four How to apply 4 Use as a standard greenback module with overcurrent defense means (1) Press the foremost to set the output voltage for your desired voltage (2) Turn the ADJ-I current adjustment potentiometer counterclockwise first, then measure the output short-circuit latest with the multimeter 10A latest vary (directly join the 2 verify leads to the output), and modify the ADJ-I fixed current potentiometer clockwise to make the output The latest reaches the overcurrent protection price you would like set (For example, the current price displayed via the multimeter is 2A, then once you use the module, the maximum recent can solely attain 2A When the current reaches 2A, the purple constant current indicator is on, in any other case the indicator is off) 4 Use as a Battery Charger A module with no fixed latest operate cannot be used to fee the battery Due to the large voltage distinction between the battery and the charger when the battery is exhausted, the charging latest is simply too huge and the battery is broken So when you start, it's best to payment the battery with a continuing current, and when it is charged to a undeniable degree, it robotically switches again to fixed voltage charging (1)Make sure you would like the waft fee voltage and fee current of the rechargeable battery; (if the lithium battery parameter is 3/2200mAh, then the waft voltage is 4, the utmost price latest is 1C, ie 2200mA) (2) Under no-load conditions, press the button to adjust the output voltage to reach the flow voltage; (If charging the three lithium battery, alter the output voltage to 4) (3) Turn the ADJ-I recent adjustment potentiometer counterclockwise first, then measure the output brief circuit current with the multimeter's 10A current vary (directly join the 2 verify leads to the output terminal) and alter the ADJ-I constant recent potentiometer clockwise Make the output current attain the predetermined charging current value; (4) Connect the battery and payment it (When atmosphere steps 1, 2, and 3: The output terminal is empty and no battery is connected) 4 Use as a High Power LED Constant Current Drive Module (1) Make yes that you just deserve to force the LED's working recent and most operating voltage; (2) Under no-load conditions, press the main to set the output voltage to the maximum LED working voltage; (3) Turn the ADJ-I latest adjustment potentiometer counterclockwise first, then measure the output short circuit current with the multimeter's 10A current range (directly join the two verify results in the output terminal) and regulate the ADJ-I constant recent potentiometer clockwise Make the output current reach the predetermined LED working current; (4) Connect the LED, examine mechanical device (When environment steps 1, 2, and 3: Output no-load LED light) 5 Note five The module enter 'IN-' mustn't ever be shorted to the output 'OUT-', in any other case the fixed latest function will fail five Please be certain that the flexibility delivery energy is larger than the power required through the output load When the module is hot, reduce the power usage! five Please learn the product description intently before use Any damage caused by mistaken use are usually not compensated
