Clear, simple, and powerful interface Intuitive controls and layout make setup and operation fast and predictable. Reduces learning time and minimizes configuration errors so you can get to work quickly. Flexible power compatibility Accepts a wide input voltage range (6–30 V) while also supporting USB 5 V supply for convenient use with power banks or USB adapters. Lets you power the device from common sources in the lab, workshop, or field without extra converters. Reliable settings retention All parameters are automatically saved when power is removed, so your configuration is retained across power cycles. Eliminates repeated reconfiguration after shutdowns or power interruptions. Safety and protection Builtin emergency stop (STOP) function provides an immediate shutdown option for urgent situations. Reverseconnection protection prevents damage if the power leads are connected backwards; the device will not be destroyed by reverse polarity. Practical applications Bench testing and prototyping: Fast, repeatable setup and parameter retention make this unit suitable for electronics development and troubleshooting. Portable/field use: USB 5 V support and a wide input range let you run the device from power banks or vehicle/industrial supplies while maintaining safety protections. Educational labs and workshops: Simple interface and emergency stop improve usability and safety for students and hobbyists.
