XY-SK120S 120W 7A Adjustable DC Power Supply Module
XY-SK120S 120W 7A Adjustable DC Power Supply Module
The XY-SK120S 120W 7A Adjustable DC Power Supply Module is a digitally controlled power supply module featuring constant voltage and constant current regulation, designed to provide an adjustable 0–40V DC output from a 6–36V DC input. Thanks to its buck-boost capability, it can not only step down the input voltage but also step it up when necessary to maintain the set output value. It offers a maximum output current of 7A and a maximum output power of 120W.
It features a solar panel charging function with MPPT support. When MPPT mode is enabled, the panel operating point coefficient can be adjusted. For battery charging applications, parameters such as the automatic charge start voltage and charge cutoff current can also be configured via the software menu.
The device includes 10 different setting memory groups. Frequently used voltage and current values can be saved and quickly recalled later.
This design makes the module highly suitable for desktop adjustable power supply applications.
