Detailed Description

General Information: The GDVLF Series of VLF-AC hipots apply the device with a microprocessor controlled, which will control voltage automatic,and can also be adjusted for manual when in the process of automatic voltage boost . Our advanced electronic design provides you with the most portable, to use VLF hipots available. An big LCD screen and onscreen instruction system can display output Sinusoidal , and the in-built thermal printer willprint the test report, make the test process is easy to operate.http://www.hvhipot.com/product-37 Features: 1. If the output voltage exceeds the limit users set , the instrument is supposed to shut-down itself, react within 20ms; 2. The high-low voltage dual protection exsit in the design, so automatic protection can be made according to the set limit of low and high voltage; 3. If the current on low voltage side exceeds the load current, the instrument is supposed to shut-down itself, react within 20ms; 4.In-built a protective resistor, no need additional resistor connected outside; 5. No capacitive rise effect in output , using negative voltage feedback circuit-closing control; 6. A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside; 7. The equipment can make it a whole according to customer needs; Specification: 1. Maximum Output Voltage: 30/40/50/60/80kV Peak (available upon request); 2.Output Modes:AC Hipot (VLF) Sinusoidal and load independent. Burn, Cable Fault Conditioning Mode; 3.VLF Test Frequencies: Selectable 0.1 Hz, 0.05Hz, 0.02 Hz, (Additional Frequencies available upon request); 4.Main Supply: 220V，50Hz AC+/-5%; 5.Measurement Accuracy: ≤3％; 6.Voltage Waveform Distortion: ≤5％; 7.Positive And Negative Voltage Peak Errors: ≤3％; 8. Duty Cycle:Continous; 9.Metering: Voltage - True RMS and/or Peak, 0.1kV ± 1% Current – 0.1mA ± 1%; 10. Environmental: (-10° C to 40° C) Humidity non condensing; 11.Computer Interface/Memory USB Port – Unlimited Test Record Storage with USB Drives; No Specialized Software Required, Automatic Storage of Results;
