Portable DC high voltage generator main technical parameters
Earth-moving machine for leveling the ground with a scraper. It is suitable for constructing roadbeds and roads, building slopes, excavating side ditch, mixing pavement materials, sweeping snow, pushing loose materials, and carrying out maintenance work on dirt roads and gravel roads. XCMG GR serial Road Paver cover 3m-12m paving width. Road Paver Road Paver,Road Construction Paver,Rubber Road Paver,Concrete Road Paver SINO HEAVY MACHINERY CO., LTD. , https://www.sinoauto-machinery.com
Working mode: intermittent use, rated load 60 minutes Voltage measurement accuracy: 1.0% (full scale) ± 2 words Current measurement accuracy:
1. Portable DC high voltage generator adopts automatic shift mode on the low voltage side, total current is 1.0% (full scale) ± 2 words. 2. The high voltage side of the portable DC high voltage generator is fully shielded and automatically shifted high-precision microampere meter, with 41 / 2 digital display, micro-ampere meter display using conductive glass and metal housing connected, excellent shielding, measuring range 0-200-2000uA, accuracy 1.0% ± 2
3, DC high voltage generator can be equipped with infrared transmission microampere meter and hand-held infrared receiver, when you can not see the high-pressure microampere meter display, you can directly read the high-voltage leakage current through the handheld infrared receiver portable DC high voltage generator Computer control technology, control PWM pulse width modulation, measurement, protection and display, the display screen adopts large-screen liquid crystal display, display output voltage, leakage current, over-voltage setting value, timer and Chinese alarm, with backlight; with timer , It is displayed on the display screen, and the time can be adjusted. When the time is near the end, there is an audible alarm.
Operating frequency: 40kHz, using closed loop large feedback ripple coefficient: ≤ 0.5%
0.75 Function: When conducting the zinc oxide surge arrester test, press the 0.75 function key, the voltage is automatically reduced to 75%, and the accuracy is ≤ 1.0%.
The grounding line of the test circuit must be in good contact, otherwise the unit refuses to work and sounds prompts. If the test power supply is a 1:1 isolation transformer or a field portable mini-generator is used as a power supply, please ground the power supply to any end of the power supply. Otherwise, it will sound an alarm. If there is no reliable ground wire on the site, you can press the “75%UDC/1mA†button on the panel for 2-3 seconds to cancel the alarm, and the instrument can still work normally.
Over-voltage setting error: ≤ 1.0%, using software setting voltage adjustment accuracy: 0.1%
Voltage regulation rate: The output voltage fluctuation range does not exceed 1.0% when the power supply voltage changes within 220V±10%
