RUZIZAO Bench Power Supply Variable, 30V 100A High 3000W DC Adjustable with Encoder Knob & Output Switch, Lab Switching Supplies 4 Digits LED Display for Repair/Test

3000W High-Power Output: 30V 100A bench power supply delivers up to 3000W. DC power supply are used in a wide range of equipment and systems, providing stable and reliable power. Equipped Stable Output Switch Button: Bench power supply can directly preset for current and voltage without “short-circuit”! Sometimes we need to switch between different voltage or current outputs, but often forget to unplug instrument, resulting in instrument burnout, a situation that often occurs in maintenance testing. The output switching function can effectively prevent damage to your equipment or load. Upgrade Encoder Knob, Four-Digit Display: The bench power supply high-precision encoder knob allow precise adjustment of the required voltage and current values. The knob can adjust each number within the range of 0-9, and the backlight 4-digit LED display screen can accurately display voltage and current values, even in low light environments. Stable Output, Auto Switch C.C/C.V Mode: The bench variable DC power supply is a low noise, low ripple, adjustable high power continuous output power supply that can work at full load for a long time. Constant voltage and constant current modes can be switched automatically. Multiple protections, Four Intelligent Cooling Fans : Safety is our top priority. The high-power output bench power supply have multiple built-in protections: over-voltage protection, over-current protection, over-heat protection, over-load protectionand termination protection. When the operating temperature reaches 122 °F/50 °C, four intelligent cooling fans can automatically turn on to reduce the temperature. The multiple protection features prevent damage to the product during operation and extend product life. CE & FCC Certification, Wide Applications: 30V 100A bench power supply passed CE & FCC Certification, high power variable power supply for a wider range of applications. Such as machine tools, metallurgy, chemical industry, electric power, used to drive hydraulic system, heating furnace, welding machine and other equipment, laboratory research (electronic experiments, material research, medical imaging), drone power supply, battery charging (LiFePO4 battery, lead-acid battery, etc.), electroplating, DIY field, etc. Packing List and After-Sales: The bench lab power supply measuring only 42 x 14 x 33 cm and weighing only 5.5 kg.
