Products features
1. Safe and convenient to operate: Full micro-computerized devices, built-in imported high-performance CPU, with high reliability, according the prompt of the interface to set test values, you need not touch the tested equipment, the equipment automatically finish the test, the test personnel far from high voltage circuit ,to ensure their personal safety.
2. Full-featured: The instrument set includes CT volt-ampere characteristic test, CT variable ratio polarity test, CT polarity test and CT one-pass current test. It automatically calculates the inflection point voltage and current value, ratio difference value, 5% or 10% error curve value, and saves the print test record and date in real time, so as to facilitate users to organize test reports.
3. High output capacity: the maximum output voltage for volt-ampere characteristic tests up to 1000V, the maximum current for ratio test up to 600A, the output capacity of equipment is 5KVA.
4. Large-screen 320 × 240 dot matrix character graphical interface, directly display volt-ampere characteristic curve after the test, graphics are clear, aesthetic, easy to analyze, equipped with micro-printer, can print the curves and test results at any time.
5. Built-in Flash memory device can store large amounts of test data, which will not be lost after power off. When the filed tests finished, people can check and print the tests results indoors.
6. U-disk dump: support U disk to dump test data, through PC to read, easy to operate.
7. PC with powerful software, beautiful outlook, easy to operate, can save and print the test results, convenient to manage the test data.
8. Apparatus can achieve AC220V and AC380V adaptive power supply. When the AC power input terminals connected to AC220V voltage, AC voltage output is 0 ~ 600 V, when the input terminals to AC380V voltage, AC voltage output is 0 ~ 1000 V. Users can choose according to actual needs.
