ZK-SK90 90W 5A Adjustable DC Power Supply Module

ZK-SK90 90W 5A Adjustable DC Power Supply Module

The ZK-SK90 90W 5A Adjustable DC Power Supply Module is an advanced digital power supply module featuring constant voltage (CV) and constant current (CC) control, capable of both stepping up and stepping down DC voltage. Operating within a 6-36V DC input range, the module offers an adjustable output voltage of 0.5-36V, an output current of 0-5A, and a maximum output power of 90W.

Thanks to its buck-boost converter architecture, the output voltage can be set either lower or higher than the input voltage. This feature offers greater operational flexibility compared to conventional DC-DC converters that function solely as step-down or step-up units.
