WWL-LDX series high-precision constant voltage & constant current linear DC power supply

Brief introduction (single phase input, super low ripple, up to 800V, 6kW)

The WWL-LDX series power supplies have high precision, high stability and perfect protection circuit. Compared to switching mode power supply, it has higher precision, lower ripple, no high frequency radiation disturbance and wider range of applications. It is widely used in electronic parts factories, universities and laboratories for aging and testing of capacitors, relays, transistors, resistors, generators and other electric products

Performance characteristic

1. Spec. range: Over 300 models available, output voltage 0~700V, output current 0~500A,output  power 0~6KW available for selection

2. Constant voltage/Constant current (CV/CC): Voltage & current are continuously adjustable from 0 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. Short alarm: Audible and visual alarm when output has a short circuit (optional)

7. Auto-discharge: used for discharging the capacitive load after shut down

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

9. Pulse working: Time controller can be equipped to make a DC pulse power supply (optional)
