Adjustable high current DC constant current power supply (DC current source)

1、 Product Introduction:

The high current DC constant current source adopts PWM high-frequency switching power supply ZVZCS soft switching conversion working principle internally, and adopts imported IGBT modules. The adjustable DC constant current power supply has specific characteristics such as high efficiency, high precision, and high stability, optimized for the high efficiency of linear power supplies and silicon rectifier power supplies. The product is more energy-saving and efficient, mainly used in scientific research institutions, laboratories, and electronic production lines that require precision power testing. The current value of the DC constant current power supply can be continuously adjusted from zero to the rated value, and the protection point can be freely selected and limited within the rated range. Simultaneously display open circuit voltage and current on LED digital display. Long term short circuit is allowed in the working state of this machine. Our company has developed a CNC programmable DC constant current power supply to cater to the market. The programmable function can be intelligently controlled through RS485 or RS232 data connection to a computer, and is equipped with upper computer monitoring software.
2、 Main features:

1. Display: Output voltage and current LED display (LCD display can be added according to customer requirements)
2. Appearance: Adopting desktop, tower or 19 inch standardized sizes, it can be combined and placed on various workbenches and racks;
3. Advantages: Small size, light weight, energy-saving and efficient
4. Constant voltage and constant current: Automatic switching of CC/CV constant voltage and constant current output, continuous linear adjustment of voltage and current values;
5. Protection functions: overvoltage protection, overcurrent protection, overtemperature protection, undervoltage protection, overload protection;
6. Short circuit characteristics: Long term short circuit under the working state of the machine;
