40KV Portable Integrated DC High Voltage Generator
The 40KV portable integrated DC high voltage generator adopts new technologies, new materials, and new components. It features high output power, small size, and light weight. It has reliable overvoltage, overcurrent, and zero-position closing protection functions, with a 0.75 times voltage latch function, and is equipped with a time relay that can set a timed audible alarm during tests. The instrument is easy to carry, simple to operate, safe and reliable, and is especially suitable for on-site testing in power departments.
Performance Features:
1. High precision and accurate measurement. The voltmeter on the control box directly displays the voltage value applied to the load test object, so no external voltage divider is needed, and wiring is simple. The instrument measures leakage current at both high and low voltage ends. The high voltage end uses a circular shielded digital display, which is resistant to discharge impact and has good anti-interference performance, suitable for on-site use.
2. High voltage adjustment stability, smooth voltage regulation across the full range. The output voltage adjustment uses a single imported multi-turn potentiometer, ensuring smooth boosting and high adjustment precision.
3. Negative polarity output, zero-start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return-to-zero, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, ensuring safe operation.
4. The 40KV portable integrated DC high voltage generator is manufactured with advanced technology and processes, using intermediate frequency voltage doubling circuits, new PWM high-frequency pulse width modulation technology, and high-power IGBT devices, resulting in higher output voltage stability and smaller ripple coefficient.
5. Added high-precision 0.75UDC1mA function, bringing great convenience to DC high voltage generator testing.
6. The overvoltage setting uses a digital DIP switch, which can directly display the set voltage value in kV, making it clear at a glance.
7. Fault sampling uses a dedicated sensor with nanosecond response time, and the optocoupler isolation element is also nanosecond-level, allowing rapid and complete shutdown of the DC main circuit, thereby greatly protecting the instrument from damage.
8. The voltage doubling cylinder is made of new materials, lightweight and sturdy. Three built-in support legs at the bottom increase the stability of the cylinder. The exterior is coated with special insulating material, providing good electrical performance and strong moisture resistance.
9. The chassis uses an aluminum alloy case, small in size, lighter, more beautiful, more reliable, simple to operate, fully featured, and suitable for field use.
