Application It is suitable for battery charging, car DVDs, car stereos, scientific research and teaching, communication equipment maintenance, LED product manufacturing tests and aging, and aging tests of electronic products. It can be used in labs, factories, schools, maintenance, electrolysis, electroplating, brush plating, lamp testing, aging testing, battery charging, home, and all other places where DC power is needed.It is an ideal choice for workers in the fields of aging test of electronic products and maintenance of communication equipment. Key Features Build to Last: This product is made of high-quality iron and plastic, 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: Over-current protection, over-temperature protection, over-power protection, and overvoltage protection functions make the product highly safe and can easily meet the 24-hour load usage requirements without burning the machine(but it is not recommended to use it at full load). The product is equipped with a fuse, which can protect electrical appliances from damage caused by overload current. Automatic Constant Voltage&Constant Current Functions: The CV indicator light is on for constant voltage output and the CC indicator light is on for constant current output. When the load current is greater than or equal to the set current limit value, the power supply automatically switches to constant current mode. When the load current falls below the set current limit, the power supply will return to Constant Voltage (CV) mode. Helpful Assistant: It delivers a stable 0 to 30V DC voltage and 0 to 10A DC current to electronic devices, ensuring accurate test results and reliable circuit operation. Energy Saving: Under the condition of ensuring stable voltage, the energy efficiency ratio of the product is as high as 85% or more, which can effectively reduce energy loss and improve energy utilization. Dual Heat Dissipation Design: There are evenly distributed heat dissipation holes on the left and right sides of the product to provide continuous and effective heat dissipation. In addition, it has a 3.15-inch smart fan, which will automatically turn on when the internal temperature of the power supply reaches a certain level, thus prolonging the service life of the product. Simple Operation: The clear 3-digit LED display provides easy-to-read resolutions of 0.1 V (100mV) and 0.01 A (10mA). Trim and Coarse knobs give you the accuracy you need. Individual output switches provide flexible voltage and current adjustment and stable output. Details Anti-slip Feet: They can prevent the machine from slipping to enhance stability and avoid scratching the tabletop. Indicator Lights: They help you to quickly understand the working status of the product, the operation mode and check whether the circuit is working properly.
