Review on π CenryKay DC-DC Buck Boost Converter with LCD Digital Voltmeter Ammeter - Adjustable 0.5V-30V, 3A Boost Drop by Ron Coleman
Easy to set up, exceeds all expectations
I am using this in a whole house UPS system to charge a small SLA battery in the main controller. There are no instructions but they are easy to find on this page. What I like best about this device CC and CV are completely independent of each other. When setting this up, I first set the voltage and then the current limit. It works well enough to replace a 12v7ah battery. At 30W it gets a bit warm, but that's enough for my purposes. I will be buying more of these to replace other small non-display power supplies.
- The voltage regulator module has an LCD display that can display input and output voltage, output current and output power; The voltage display resolution is 0.05V, the current display resolution is 0.005A.
- Almost OK
