October 12 22:04:28, 2022

Usage: Surge Arrester Testing
Output Current: 2mA,3mA, 5mA
Ambient Temp: -15degrees-50degrees
Trademark: HVGRAND
Specification: different sizes
Origin: China
Application
Portable DC high voltage generator is applied in electric power department, industrial enterprises and power departments, R & D institution , railway, chemical industry, power plant, etc for MOA, magnetic blow-out arrester, power cable, generator, transformer, switch to  carry out DC high voltage test.

Advantages and features
1) small volume, light quality, beautiful appearance, reliable, easy operation, complete function, and suitable for outdoor use
2) LCD monitor with large screen to display output DC voltage, current, over voltage setting, timing, grounding, etc
3) Applying the latest PUM intelligent pulse width modulation, pulse string array logic modulation and high-power IGBT device with frequency up to 40 KHZ to make the output high voltage more stable and ripple coefficient smaller
4) Initiating intelligent poor grounding protection and alarm function, pressure circuit disconnection protection, scram button to improve security
5) With automatic step-up voltage, timing and data storage
6) Double pressure cylinder with segmental structure to be flexible, convenient and multi-purpose in field use.
