Versatile HANMATEK HM305 Switching Variable Control Review

【Auto Power Calculation】 - Intelligently calculates output voltage and current into power and displays the value on its large screen.; decimal point automatic carry & LED 4 digits display of voltage function displays.current and powe; The keyboard can be locked to prevent misoperation. 【Output switch control】 - Sometimes we need to switch between different voltage or current outputs, but we often forget to unplug the previous instrument and cause the instrument to burn out.which often occurs in the maintenance.Output key is designed to solve this problem.By pressing the Output key, the required voltage and current can be adjusted without the actual output power,Which makes this DC power supply more secure and more energy efficient. 【Safe and Reliable to Use】 - Safety is our priority. The built-in fan low arc noise & low ripple,The power supply is durable and compact. Productive work since the power supply comes multiple protection of Over-voltage, over-current, over-power, over-temperature, short-circuit powerful protection function. 【Wide Application】 - Applied in production line test, electrical maintenance, aging products, battery charging, laboratories scientific research and teaching and all other need DC regulated power supply.Nice gift choice for DIY electronics hobbyist. 【Package Included】 - 1 * HM305 Power supply host , 1 * Output power cord , 1* Input power cord , 1 * User manual.High quality material adopted and make it more stable output, small volume, light weight, easy to carry and move and easy operation.
