Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. It is a non-insulated DC regulated power converter module with a long service life. High power and stable output power, converts 5-30VDC to 1,25-30VDC. High-quality components ensure high conversion efficiency, do 93%. Supports overcurrent, short-circuit, over temperature protection. Designed with two heat sinks for better heat dissipation. - Inner mesh panties Type: Non-isolated synchronous straightening automatically increases/decreases module Input voltage: DC5-30V Input current: 8A, (MAX) 10A, (within 6A for long-term operation) Resting current: 4mA (there will be a deviation when the operating voltage is different) Output voltage: 1,25-30 V steplessly adjustable Output current: 10A (MAX) (long-term natural cooling within 5A, reduce the rated value at high output voltage), increase heat dissipation or reduce the rated value when the module temperature exceeds 65 Permanent output current range: 0,2-10A Working temperature: -40 do 85 Frequency: 150 KHz Conversion efficiency: Typical 91%, maximum 93% Overcurrent protection: yes Circuit protection: Yes (current limiting protection) Protection against overheating: Yes (automatic reduction of output voltage) Reverse input protection: No, connect the diode in series at the input if necessary Output flow protection: Yes, you do not need to add a diode when using do charging. Cable method: terminal block output (input is input, output) Weight: 70g/2,5 oz (approximately) Package list:1 * module Current regulation: 1, adjust the CV potentiometer, set the output voltage according to the load requirements. 2, turn the CC potentiometer to the left by about 30 circles (i.e. The output current is set to a minimum), connected do LED diodes, set the CC potentiometer to the required current. If you are using a battery do , connect do the output after the battery is fully discharged. Adjust CC do of the required current. Because the more energy is left in the battery, the less charging current will be. Please do not use the short circuit do current regulation.
