CC/CV DC-DC Buck-Boost Converter 40W/90W Lab Power

Power up your lab with the CC/CV DC-DC Buck-Boost Converter, delivering 40W (SK40) or 90W (SK90) of adjustable, regulated output in a compact module. It accepts 6–36V input and provides 0.5–36V output with up to 4.5A (SK40) or 5A (SK90), enabling precise CC/CV control for test benches, battery projects, motor drives, and electronics experiments.

The unit features an independent silicone keypad for fast voltage or current entry and a 1.8-inch color screen for intuitive monitoring. It stores settings in 11 data groups for quick recall, and the external fan port can be extended to help manage heat at higher loads. Note: SK40 version operates without an internal fan.

Benefits & Tips

• Use for stable, configurable CC/CV power in electronics testing, battery charging, and lab experiments requiring precise voltage and current control.
• Save frequently used setups as data groups (up to 11) to speed up repeated measurements or prototyping sessions.
• Plan cooling when running near the upper end of 40W/90W; the SK40 variant ships without a fan, while airflow may be beneficial at higher loads.
