The high-precision programmable controller of the programmable DC power supply is composed of a processing unit (CPU), several peripheral devices and interfaces, and a communication network connected to the external devices. Its main task is to detect various physical quantities on site. , transform and manipulate, and represent these quantities in a consistent way.

Programmable DC power supply is a switching regulated power supply that can control the input voltage and output voltage. It has an automatic adjustment function. It uses a microprocessor chip as the control unit internally, and converts the input through sampling circuits, comparators and operational amplifiers. The voltage or current signal is converted into a digital signal, and then the digital signal is processed by the DSP, and corresponding actions occur according to the set program, thereby completing functions such as voltage stabilization and current limiting.

High-precision programmable controller is an intelligent new generation industrial control computer system that has been produced with the rapid development of electronic technology and computer technology in recent years.

It is based on a microprocessor, using single-chip microcomputer and special-purpose large-scale integrated circuits. In terms of hardware, it has completed ultra-large-scale integration and uses a lot of today's semiconductor manufacturing;

In terms of software, an object-oriented planning method is adopted to enable users to use the system conveniently.

Because the high-precision programmable controller is based on a single-chip microcomputer and adds some peripheral circuits, it is still a single-chip microcomputer.

Due to the addition of some peripherals, the functionality of the system has been greatly enhanced, and the reliability has also been improved.

Because many peripherals have been added, the structure of the system has become more compact and the cost has been reduced accordingly.

Due to the modular and standardized design, product maintenance and upgrades become very simple.

It has the characteristics of stable output voltage, small ripple, high efficiency and soft start. Programmable high-precision DC power supply is more and more widely used in the fields of industrial automation and power electronics, and its technology is also changing with each passing day and constantly updated and developed.
