XY-SKxxH DC-DC Buck-Boost converter CC/CV with LCD display, 5-36V

Product detailed description

Adjustable DC-DC Buck-Boost converter with an LCD display that can both decrease and increase the output voltage – so you are not limited by whether the source is higher or lower than the required output. The module operates in both constant voltage (CV) and constant current (CC) modes, making it easy to create a small laboratory power supply, a charger for lead-acid or Li-ion batteries, a power source for LEDs, or a regulator for a solar panel. The large display provides a clear overview of voltage, current, power, transferred capacity, energy, and operating time. Everything is adjusted using a rotary encoder and three buttons, and you can lock the values to prevent accidental changes. Thanks to the front panel, you can mount it directly into a box or device.

Package contents:

• 1× DC-DC Buck-Boost converter XY-SKxxH (depending on the chosen variant)

Note:

• This product is not a standalone functional unit and may require professional installation.
• The stated power applies with sufficient cooling. For continuous loads at the power limit, we recommend adding active cooling.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
