Product Introduction
. Dongxinchi Energy Technology Co., Ltd. specializes in the production of DC power supplies, adjustable DC regulated power supplies, high-frequency switching power supplies, digital display adjustable power supplies, constant voltage and constant current power supplies, high-power DC power supplies Power supply, switching regulated power supply, aging experiment test power supply, adjustable DC power supply, adjustable regulated power supply, adjustable switching power supply.
.The DC stabilized voltage and current power supply adopts the working principle of high-frequency switching power supply and adopts imported modules. Specific features such as high efficiency, high precision, and high stability are optimized for the high efficiency of linear power supplies and silicon rectifier power supplies. The products are more energy-saving and efficient and are mainly used in scientific research institutions, laboratories, and electronic production lines when precision power testing is required. Alias: adjustable switching power supply, adjustable DC regulated power supply, high-power DC regulated power supply, DC adjustable regulated power supply, DC power supply, high-power DC power supply.
. The current power supply voltage and current value are continuously adjustable from zero to the rated value, and the constant voltage and constant current are automatically converted. The protection points can be selected arbitrarily within the rated range and limited. Voltage and current are displayed by digital tube at the same time. This DC power supply is widely used in laboratories of various colleges and universities, automatic test equipment, electronic inspection equipment, production lines, resistors, relays, motors and other electronic components, routine testing, electrolytic capacitors, and tantalum capacitors. Communication equipment. Automatic aging equipment and other occasions that require DC power supply.
