Detailed Description

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 Features: 1) Over 300 models available 2) Range: 0 ~ (0 - 700V), 0 ~ (0 - 500A), 0 ~ (0 - 6kW) optional 3) Automatically exchanges between constant voltage mode and constant current mode 4) Low ripple and noise rate 5) Fast response 6) Constant current can be checked or set during operation 7) Low input current, high reliability, higher efficiency and less line distortion due to the choke input circuit 8) Over voltage protection unit (OVP) is equipped as standard 9) Output on / off switch 10) Remote sensing terminals option 11) Operating status is indicated by LED 12) External analog control option 13) 16 bit D/A card for PC ISA (optional) Specifications : 1) CV/CC: Voltage/current continuously adjustable from 0 to rated value, auto switching between CC and CV mode 2) Precision (CV): Line regulation: ≤0.1% Of the rated value (+/-10% input voltage change); Stability: ≤0.3% of the rated value (continuously working over 8 hours); Temperature Coefficient: ≤0.04% of the rated value; Load regulation: ≤0.2% of the rated value (load 0~100%) 3) Precision (CC): Line regulation: ≤0.1% Of the rated value (+/-10% input voltage change); Stability: ≤1% of the rated value (continuously working over 8 hours); Temperature Coefficient: ≤0.04% of the rated value; Load regulation: ≤0.2% of the rated value (load 0~100%) 4) Ripple (RMS): CV: ≤0.01% of the rated value+10mV; CC: ≤0.2% of the rated value+10mA (Range: 80%~100% rated output) 5) Output voltage / current setting: 10-turn Potentiometer (standard); LCD touch screen (optional) 6) Display mode: Voltage/current LED digital display (standard); LCD display (optional); LCD touch screen (optional) 7) Read output: Single-phase AC 220V±10% 50Hz±10% 8) Short protection: Withstand long-term short and start-up short 9) Protection mode: Over voltage and over load protections, over current protection with alarm 10) Working mode: Withstand long-term continuously working at full load FOB Price Payment Terms: L/C D/P T/T Min.
