KUAIQU 30V 10A Variable DC Power Supply with 4-Digit LED Display Output Switch USB Output 5V/2A (White)

【Output Switch Control】Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT (ON/OFF) key is designed to solve this problem, just with a single press of the added OUTPUT (ON/OFF) key, you can easily turn the output on or off. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving. Also, you don't need to remove the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use 【Precise 4-digit LED Display, Auto Power Calculation】The KUAIQU power supply variable is a professional switching power supply regulation device with a high resolution of 0.01V and 0.001A. The variable power supply features a big bright 4-digit LED display that shows the adjustable power supply output values of Voltage (V) / Current (A) / Power (W) in real-time. The high-definition backlit 4-digit LED display provides an accurate and clear readout for the voltage, current and power values even if you are in low-light condition 【Various Applications】This benchtop power supply is suitable for battery charging ( LiFePO4, lead acid batteries, etc.), electronics repair, communication equipment maintenance, electrolysis, electroplating, brush plating, lamp test, aging test, burn-in test, production line test, DIY, labs, schools, laboratories scientific research and teaching etc. The KUAIQU power supply is a nice choice for beginners or professional electricians and DIY electronics hobbyist
