Product description: Withstand voltage test instrument is designed according to the relevant provisions of the safety standards of GB4706.1, IEC 60335, complying with CCC, UL, VDE, CSA, JIS test standards, which is an ideal instrument for safety withstand voltage test of wires and cables, household appliances, industrial appliances, electrical, chemical and medical instrumentation, and the whole machines of electronic products. Adopted the advanced digital circuit technology, enable to automatically control on and off for the output voltage. When the leakage current of measured items exceeds the set value during the test, the output voltage can be automatically cut off, and realize timing test. The test voltage, leakage current, test time of the instrument all are digital display, breakdown voltage and leakage current values of test items can be intuitive, accurate, fast and reliable measured Technical parameters: Model number LK2670AX LK2671B LK2672D Test voltage AC 0~5kv AC/DC 0~10kv AC 0~5kv Leakage current AC 0~2/20mA AC 0~2/20/50mA DC 0~2/10mA AC 0~200mA Test time 1~99s 1~99s 1~99s Transformer capacity 100VA 500VA 1000VA Measurement accuracy ±3% ±3% ±3% Others With superleak alarm With superleak alarm With superleak alarm
