DC power supply

DLC9000 linear power supply series

DLC9000 linear power supply series






The DLC9000 series linear programmable DC power supply adopts a pure linear production method, with constant voltage, constant current, and constant power output modes. It can automatically cross-convert, maintain control and protection characteristics, and ensure the high precision, low ripple, and output of the DC power supply. The voltage and current dynamic response speed is fast, and the products are mainly positioned in the electronic power production, PCB board manufacturing industry and communications, PLC power supply, automatic test system integration, medical equipment, and laboratories for high-precision DC power supplies. Used to replace imported low-power DC power supply products.




DLC9000 series programmable linear DC power supply is a high-power and high-precision DC power supply with AC single three-phase input and DC output, the maximum power can reach 400KW.

This series of power supplies have excellent electronic characteristics such as ultra-high accuracy, precision and stability, and can provide high-power ultra-low ripple DC power supplies on the production line, making the product performance more perfect. It has a complete protection circuit. Compared with the switching power supply, it has the advantages of high precision, small ripple, no high-frequency radiation interference, and wide application occasions.

This series of products is an ideal DC stabilized power supply, which can be widely used in factories, schools, research institutes, laboratories and various departments of the national economy.
