The DC power supply variable is a type of power supply device whose main function is to convert an unstable input voltage into a stable output voltage to meet the requirements of various electronic devices for power supply voltage. Application It is suitable for labs, schools, maintenance, electrolysis, electroplating, brush plating, bulb testing, aging testing, battery charging, home DIY, and other requirements. Key Features High-quality Material: The product is made of metal, which is hard, anti-deformable, corrosion-resistant, impact-resistant, and heat-resistant, ensuring a long service life. C.V. and C.C. Modes Automatically Switching: Two modes can be automatically switched with load change. If the load current is equal to or greater than the preset current limit, it can be used as a C.V. source. If the load current is less than the preset current limit, the device will automatically switch to C.C. mode and the voltage will be reduced. It can automatically calculate the power value based on voltage and current. High Accuracy: With a display resolution of 0.1V and 0.01A, you can easily adjust it in the range of 0-60V and 0-5A. And the 3-digit LED display provides more accurate readings of voltage and current values. Excellent Performance: It has small voltage fluctuation, low noise, stable output, and low interference, which can maintain a comfortable working environment and improve working efficiency. Easy to Operate: With a large LED screen and sensitive knobs, it allows you to monitor the working status and adjust the voltage and current more conveniently. Safer to Use: Overcurrent protection, under voltage protection, overload protection, delay protection, multiple vents, and a built-in cooling fan can effectively ensure safety during use, so you can use them with confidence. Details Indicator Lights: They can clearly show the constant voltage (C.V.) or constant current (C.C.) mode, making it easier for you to keep track of the product's working status. Anti-slip Feet: Four anti-slip feet can keep the product stable. Protective Package.
