Overview of Linear High Power DC Voltage and Current Stabilized Power Supply

Linear high-power DC voltage and current stabilized power supply can be used for aging and testing of components such as capacitors, relays, resistors, etc. It can also be used for experimental testing of electronic components such as thermistors and motors. At present, many well-known capacitor manufacturers, resistor factories and other electronic component production units and scientific research institutions and other research and development units have adopted this series of power supplies and have received high praise.

The linear high-power DC voltage and current stabilizer is a high-precision power supply with single-phase or three-phase input and high-power DC output, which can reach 400kW. It has excellent electronic characteristics such as ultra-high accuracy, high precision, and high stability. It can provide high-power ultra-low ripple DC power supply on the production line, making the product performance more perfect. It has a complete protection circuit and can better meet the user's simple and convenient use needs. Compared with the switching power supply, it has the advantages of high precision, small ripple, no high-frequency radiation interference, and wide application occasions.

The linear high-power DC voltage and current stabilized power supply can be equipped with an intelligent monitoring 232 interface. Through the perfect combination of software and hardware, the existing DC power supply is combined with high-tech with computers as the core, and an intelligent monitoring module and an interface circuit for communicating with computers are added, so as to realize the remote control of the operation and stop of the DC power supply through the computer. With the support of relevant software, the output voltage and current of the DC power supply can be set. It replaces the cumbersome manual operation and enhances the integration and safety of DC power supply products.

The working condition of the linear high-power DC voltage and current stabilized power supply equipped with an intelligent monitoring 232 interface can be displayed on the computer screen in the form of graphic curves and real-time data, which is intuitive and reliable. If the DC power supply fails, the fault signal can be sent to the computer through the 232 interface in time, and the DC power supply can be shut down immediately. The supporting software of the DC power supply can realize the scaling of the graphic curve and the mouse point selection function, which is conducive to the analysis of researchers, and the operation data of any time period can be saved to the database. Automatically monitor the working voltage, current, and working time of the power supply, and draw a curve graph. The data can be automatically saved and supported for printing.

Performance characteristics

1. Specification range: Nearly 300 specifications, output voltage 0-700V, output current 0-500A, output power 0-6kW

2. Constant voltage and constant current: voltage and current values ​​can be adjusted continuously from zero to rated value, and constant voltage and constant current can be automatically converted

3. Overcurrent alarm: The alarm current value is continuously adjustable from 0 to 120% of the rated value. When the power supply output current exceeds the current alarm value, an audible and visual alarm will sound.

4. Overvoltage protection: The voltage protection value is continuously adjustable from 0 to 120% of the rated value. When the power supply output voltage exceeds the voltage protection value, the circuit breaker will trip for protection.

5. Short circuit protection: Allow long-term short circuit or short circuit start-up in any working state

6. Overload protection: When the power supply or load fails and the output current exceeds 1.5 times the rated value, the power supply will trip for protection
