Weight: 1.0 kg Item Description ?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? - Front 5V 2A USB charging interface that can be charge your devices.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. ?Manufacturer's Package? - 1 * HM310 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. Product Description 110V Input Voltage Upgraded HM310 Mini DC Power Supply The 2020 upgraded HM310 has an amazing design. The full-screen design and the all-metal body make it look so exquisite. Compared with similar products, it has a smaller size, only 9.0inx5.9inx3.1in, compact and portable. Based on feedback from a large number of users, we have increased Output Switch control, Anti-collision lock and other practical functions. We used a better circuit board. This variable DC power supply is a very stable, regulated DC power supply. It has the characteristics of low ripple and noise, high accuracy, high reliability, perfect overload and short circuit protection circuits, and it is especially suitable for laboratory, school and electronic maintenance. Designed for laboratory and industrial use. Output Switch Control Sometimes we need to switch another voltage or current , 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 long pressing the Output button,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. 5V 2A charging port Equipped with 5V 2A charging port which can quick charge your devices. Compact and Portable Due to the use of a more compact circuit board, this DC regulated power supply is also more compact under the conditions of richer functions and higher accuracy, the performance is beyond linear power supply. Compared with liner DC power supply, more compact, lighter, portable and Compact and the size is only 9.0inx5.9inx3.1in High precision The voltage readback resolution is 0.01V and the current readback resolution is 0.001A.
