Description of πŸ”Œ CenryKay DC-DC Buck Boost Converter with LCD Digital Voltmeter Ammeter - Adjustable 0.5V-30V, 3A Boost Drop

The liquid crystal can display the input and output voltage and the output current output power. buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current range is 0-3A, can be arbitrary adjustable, if enhance heat dissipation, it can reach 4A; max output power is 35W, if enhance dissipation, it can reach 50W. Button control: The button controls the output voltage ON / OFF state, and the default output state at the next power-on can be set to ON or OFF. The voltage regulator module adopts LCD design, which can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A. Small output ripple, LC filter; heat sink, module support spacer.

Not Worth Your Money

I purchased this product for use in my automotive shop, but I was deeply disappointed. Thanks to my knowledge gained in practice, I was able to identify that the display was faulty and the voltage output was not consistent. While the concept may seem useful, this converter simply did not live up to its promises. Save your money and invest in a product with better quality control.

Pros
  • None
Cons
  • Faulty display, inconsistent voltage output

With built-in voltmeter and ammeter

I used them to make adjustable bench power supplies and adjustable chargers. The only problem is that the input voltage is limited to 30VDC, as the rectified 24VAC voltage can rise above the input threshold and cause the power to cut off (a very minor issue for me).

Pros
  • Button Control: The button controls the ON/OFF state of the output voltage, and the default state of the output can be set to ON or OFF at the next power-up.
Cons
  • 0

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…

Pros
  • 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.
Cons
  • Almost OK
