Feature: 1. WPS3010B 10A/30V/300W digital display programmable switching DC regulated power supply, which can display voltage, current and power at the same time. 2. It is suitable for product aging, research and development tests, schools and production lines. The output voltage and output current are preadjusted by the encoder knob, which can be continuously adjusted between 0 and the nominal value. 3. The stability and ripple coefficient of the power supply are very good, with various protection circuits such as short circuit protection, over voltage protection, over current protection, and over temperature protection. 4. The design is artistic and easy to operate, and it can work at full capacity for a long time. This machine is equipped with a USB power supply interface and a computer PC software control function. 5. Durable, made of high quality sheet metal + ABS material, not easy to damage, long service life, and can be used for a long time.
