Description
Specification： Input: DC3. 2V~40Vinput voltage must be 1. 5 V higher than the output voltage, no boost Output: DC1. 25V~35V , voltage is continuously adjustable maximum output current : 3 A Output ripple: 1. connect to power source 2. adjust the swirl button on the blue potentiometer 3 monitor voltage with multimeter to get the needed voltage . Note： 1. We have tested these voltages, they are very high at the maximum voltage By default, takes about 15-20 turns before the voltage starts ramping down. 2. When the output is below 2A, it is not necessary to add a heat sink for a long time. However, when the output current is higher than 2. 5A (or the output power is higher than 10W) for a long time, please add a heat sink. Actually tested when 12V input, 5V output, current 1A, load regulation rate is less than 1%. 3. The input and output interface can not be reversed. It is a buck module, the input voltage must be higher than the output voltage
Features
- 0.1UF high frequency bypass capacitor can filter out high frequency noise effectively
- High precision potentiometer，when it is clockwise, it means boost，when it is counterclockwise, it means buck
- the Buck Converter use SANYO solid-state capacitors, high-Q inductance with LED indicator output，and 36 u thickening circuit boards
- Output ripple:<30mV
