Product Highlights- 3. it can be boosted and bucked, 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 state of the output terminal, and can be set to be on or off by default after power-on.
- Input voltage: 5.5-30v (when the input voltage is 5v, it can also realize buck-boost, but the measurement of voltage and current is not accurate; when it is lower than 4.7v, it will be under-voltage protection).
- 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 connection will 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.
- 6. using a buck-boost chip as the main controller, an external 60v 75a mos tube as a switch tube, dual 60v 5a ss56 schottky for rectification, sufficient voltage resistance and sufficient power, which is better than the immature xl6009/lm2577 solution on the market (many pieces of 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 enhanced heat dissipation. output power: natural heat dissipation 35w, enhanced heat dissipation 50w.
