Feature: 1. Constant power design provides a combination of multiple ranges of voltage and current settings, allowing users to provide flexible configurations of higher voltage and larger current within the rated power range. 2. Large‑screen LCD display, rich display content. The operation process is simple and convenient, equipped with a visual interface display system, which is easy to use. 3. Original voltage/current change curve, monitoring function. With overvoltage/overcurrent protection function. The body is small, portable and easy to use. 4. Low ripple, low noise, meet high‑precision test requirements. The intelligent temperature‑controlled fan dissipates heat, reduces noise interference, and runs more stable. 5. 5 groups of commonly used data can be stored for easy recall at any time. Constant voltage/constant current mode can be set to protect circuit devices. Support RS232 host computer programming output, SCPI digital communication function.
