GDYD-3000 Programmed Power-frequencyVoltage Withstand Test System Introduction GDYD-3000 is designed according to the DL/848.2-2004 standare. It is used to proceed insulating strength test of kinds of such as electronic equipment, electric elements, insulated materials and so on,on purpose of testing the insulating level , finding the insulating bug of tested res and weight the ability of overpotential of them. Features • Programmed Voltage Regulating • Auto/Manual Regulating Mode • Voltage, Current, Time Setting • Four display windows for Output Voltage(HV), Output Current(HC), Input Current, and Withstand Time • Auto Detecting Inertia of Motor, step-by-step, try-and-error Voltage Regulating Method • Auto Timing at Setting Voltage, when Time up, Auto Regulating down to Bottom • Auto Shut off when over Setting Current(one of the input and output current), and Auto Regulating down to bottom, and Sound an Alarm • Auto Capture Peak Voltage when break down •Test data can
