Very versatile EXTREMELY HIGH PRECISION Step Up Step down DC DC Converter Buck & Boost Complete with voltage display and constant current & voltage making set up a breeze This low cost type of device is a game changer that could make your laboratory power supply obsolete.

I import a lot of Electronic modules from China and this one is particularly high quality. Check the photos

Input voltage: 5.5-30V (Can be lower than 5.5V but display not accurate then) Output voltage: 0.5-30V Output current: stable operation for 3A long term. will accept 4A short term but watch for heating, Output power: 35W natural heat dissipation, Forced ventilation 50W Voltage display resolution: 0.05V Current display resolution: 0.005A Conversion efficiency: about 88% Soft start: Yes (startup may fail under very heavy load) Input reverse protection: yes Short circuit protection: yes Working frequency: 180KHZ Size: length * width * height 66 * 48 * 21 mm Mounting hole: diameter 4mm

Ideal for battery charging and very suitable for solar panels and any other fluctuating power sources. Also great for choosing "Any battery" "for "any application" and getting constant voltage out as you battery discharges. For example a standard LI -ion cell has a voltage from 4.2 fully charged to 3.5 volts when its 90% discharged With this unit you can output any rock steady regulated voltage you wish up to 26V over the whole discharge cycle of the battery & output voltage..Rotation of the high precision 30 turn potentiometer minutely adjusts the output voltage.
