Yihua 3005D-IV 30V 5A Large Screen Digital Display High Precision Adjustable DC Laboratory Power Supply For smart phone repair power tool. Features: Powerful enough to load computers, mobile phones, printers, projectors, refrigerators, and other appliances. USB fast charging: fast as lightning, supports a variety of fast charging protocols, multiple protection short circuit alarm, 5V/4A, 9V/2.5A, 12V/2A, automatic recognition matching. High precision regulation, adjustment accuracy: 1 mA 10 mV, display accuracy: 1 mA 10 mV. One key to converting the output voltage range, 30V voltage can be quickly converted to 0-5V gear, mobile phone maintenance more secure. Multiple protection, safe, efficient, and stable, over-voltage, over-current, overload, overheat, short-circuit protection. Full load continuous work durable, not easy to damage. Low-frequency interference and noise reduction design, small voltage fluctuation, strong load carrying capacity, stable output, not easy to interfere. Temperature-controlled fan automatically turns on intelligent heat dissipation, when the internal temperature of the power supply reaches a certain temperature, the fan automatically turns on heat dissipation. Material sufficient, reasonable circuit design, a power sufficient output guaranteed. Suitable for most maintenance test scenarios, such as home appliance maintenance, DIY experiments, factory assembly lines, aging tests, etc. Specification: Model No: 3005D-IV Power: 220W Display Format: LCD large screen display Output Voltage: DC 0~5V/0~30V Output power: 150W Load Stability:
