Functional Features

WT-B系列数×质皆鸭湟峭际Observe subtle changes in the rising edge of low-inductance coil waveform in real time using high-speed A/D conversion technique; identify the quality of low-inductance coils (>1μH) tested

Built-in precision IGBT high voltage SMPS, MCU programmable automatic voltage regulator, to ensure that the test process is immune to external grid voltage fluctuations

Manual mode and visual identification, arbitrary waveform zoom, quick and accurate judgment under auto mode

In addition to providing waveform area comparison, waveform difference area comparison and waveform phase comparison, the corona discharge comparison is also available

Take an HV thyristor module (instead of inflatable hydrogen thyratron) made by proprietary technique as an HV switching device to reduce user costs significantly and improve product stability, reliability greatly; no waiting for preheat, the tester starts work upon boot

Standardized, modular design, exquisite manufacturing workmanship, simple structure, easy operation and maintenance

Set and remove management authorization by double passwords for easy management

Offer multiple combinations suitable for users’ specific or upgrade needs

A/D maximum conversion rate optional, up to 40MHz

Number of wave types stored optional, up to 800 types

Corona discharge comparison optional

Take 0.5-2 seconds only to test coil windings with any number of armature bars automatically

Multi-winding coil test optional
