Pack of 6. Using a buck boost chip as the main regulator, an external 60V 75A MOS tube as a switching tube, dual 60V 5A SS56 Schottky for equivalence, sufficient voltage resistance and sufficient power, which is better than the immature XL6009/LM2577 solution on the market (many pressure and flow resistance performance can not reach
Output voltage 0.5-30V output current: it can work stably at 3A for a long time, and it can reach 4A with improved heat dissipation. Output power: natural heat dissipation 35W, improved heat dissipation 50W.
Input voltage: 5.5-30V (if the input voltage is 5V, it can also realize buck boost, but the measurement of voltage and current is not accurate; if it is lower than 4.7V, it will be undervoltage protection).
3. It can be reinforced and baked, the output voltage can be adjusted arbitrarily from 0.5-30V, and the limit current can be adjusted arbitrarily from 0-4A. 4. The button controls the on/off status of the output terminal and can be set to ON or OFF by default after switching on.
1. LCD can display input and output voltage, output current and output power. 2. The input terminal is protected against reverse connection, and the reverse connector does not burn out. 3. The output terminal is anti-inverting, and there is no need to add an anti-inverting diode when charging the battery.
