Build to Last: This product is made of high-quality ABS, with a spray painting process, which is scratch-resistant, tear-resistant, rust-resistant, and not easy to deform, keeping the product sturdy and practical for long-term use. High Safety: Short-circuit protection, over-temperature protection, overload protection, and overvoltage protection functions and equipped fuse make the product highly safe. In addition, the product is equipped with an anti-reverse connection to better protect user devices. High Accuracy:It supports 0-30V voltage output and 0-5A current output. The voltage display precision is ±1% + 1 digits, and the current display precision is ±1% + 2 digits, providing more accurate voltage and current readings. Powerful Function: It can automatically switch between C.C. and C.V. modes, and can be used as a constant voltage (C.V.) power supply and constant current (C.C.) power supply even when the load changes, ensuring stable output voltage or current. Energy Saving: Under the condition of ensuring voltage stability, the energy efficiency ratio of the product is as high as 85%, which can effectively improve energy utilization.Good Heat Dissipation: The built-in cooling fan will automatically turn on when the internal temperature of the power supply reaches a certain level, ensuring stable operation and prolonging the service life of the product.
