Switching Mode DC Power Supply

small size, low weight, high efficiency, quick response time, high precision and stability, protective circuit, DC power supply

Brief introduction (small size, low weight, high efficiency, 200W-50kW, 0-10kA)This series power supply have high precision, high stability and perfect protective circuit. Compared to linear power supply, it has higher efficiency, quicker response time, less weight and smaller size etc. It is now widely used in storage cell, PCB, communication, PLC power up and motor aging test industries.

 

Performance characteristic

1. Output range: 200W~50KW, 0~10KA, 0~1KV

2. Constant voltage/Constant current (CV/CC): Voltage & current are continuously adjustable from 5% to rated value, auto-switching between CV mode and CC mode

3. Over voltage protection: Over voltage value continuously adjustable from 0 to 110% rated value, auto-shut down when output voltage exceeds the over voltage set point

4. Short protection: Withstanding long-term continuous work or starting up in short status

5. Over load protection: Auto-shut down when power supply or load goes wrong, or output current exceeds 1.5 times of rated value

6. Output display: Voltage & current both LED digital display (standard), LCD display (optional) or LCD touch screen display (optional)

7. Intelligence: By connecting to the computer, it can be monitored through computers as an intelligent power supply

 

Main application

1. Storage cell charging, PCB exposure lamp power supply

2. Electronic parts testing, such as relays, resistors, motors, and transistors aging & routine testing

3. Laboratories, electronic equipments, and auto-test equipments

4. Electronic test & communication equipments and assembly line equipments

5. Other occasion that needs switching mode power supply
