Company Profile

The company specializes in the research anddevelopment, production, sales, and service of electric power systemautomation testing equipment, providing customers with one-stopservices.

Product Introduction

This instrument is suitable for electric power, railway, chemical industry, mining, metallurgy, iron and steel and other departments of zinc oxide surge arrester, magnetic arrester, power cable, transformer, generator and other equipment for DC voltage test and leakage test, can also be used for electrostatic dust, spray and other power.

Functional Characteristics

1. Output voltage stability: the use of the latest PWM pulse width modulation technology and voltage current double closed-loop feedback technology, improve the power supply adjustment rate and load adjustment rate, so that the high voltage stability, low ripple. Full range smooth voltage regulator, output voltage high accuracy. The host voltage meter directly displays the voltage value of the load, without additional voltage divider, the wiring operation is simple. Voltage resolution 0.1kV, current resolution 1uA.
2. Comprehensive protection: full range of protection function, with zero position protection, over current protection, over
voltage protection, breakdown protection, protection circuit use nanosecond special sensors, the action is fast and reliable, and effectively protect the safety of people and equipment.
3. 0.75U function: the intelligent high precision 0.75U function button, press this button, voltage current automatically up to the 0.75U state, which is conducive to the oxidation of zinc oxide arrester test.
4. Zero boost voltage: the boost potentiometer zero, the use of imported multi – loop potentiometer, the process of stable, high- accuracy.
5. Over voltage setting: digital dial switch is used in the setting of over voltage, and the operation is simple, has higher
6. Integrated design: use of integrated design, the host and the cylinder placed in a box. Select high frequency high voltage rectifier diode, so small volume, improves the efficiency of the whole machine, easy to carry.
7. Reliable performance: the key components are high performance imported components, the appearance of the cylinder coated with special insulation materials, electrical performance is good, moisture resistance, no leakage.
8. Simple operation: the function of the instrument interface buttons, reasonable layout, clear instructions, easy to learn and use.
