■ Product Overview

Vs series portable high current generator (referred to as current lifter) adopts numerical control technology and has strong anti-interference ability. Compared with the previous generation of current lifter, the converter made of low-power, high-capacity self coupling voltage regulator and high permeability iron core has the advantages of large output power, small volume and light weight. It is mainly used in primary bus protection and transformation ratio test projects of various current transformers. It is widely used in scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgy, mining and other enterprises.

■ functional features

▲ directly display the test values of primary current and secondary current, which is convenient for test observation and recording.

▲ high measurement accuracy: level 0.5.

▲ small volume, light weight, only 30% ~ 70% of the volume of similar products, which is very convenient to carry.

▲ six and a half digit liquid crystal display of voltage and current, with higher display accuracy and more accurate experimental results.

▲ 128 * 64 dot matrix liquid crystal display, more intuitive data display and faster reading.

▲ instrument display locking function, especially for more accurate and faster reading of transformer ratio test.

▲ polarity measurement, automatic measurement of transformer polarity, without separate experiment.

▲ add self-locking function.

▲ automatic detection function of transformation ratio.
