Programmable Withstanding Voltage & Insulation Tester

The LS9923 Programmable Withstanding Voltage & Insulation Tester is an integrated testing device developed by LISUN specifically for the safety inspection of electrical products. It centrally integrates two key functions: AC/DC withstand voltage testing and insulation resistance testing. It can accurately evaluate the insulation performance and breakdown resistance of electronic products under high-voltage conditions, and is widely suitable for compliance testing needs of electrical products in multiple fields such as household, industrial, and medical.

The LS9923 adopts a high-precision voltage sampling module and a fast overcurrent protection circuit. Its output voltage range covers AC/DC 0~5.00KV, and the overcurrent cutoff speed is fast (millisecond-level response), which can effectively avoid irreversible damage to the tested equipment caused by continuous high-voltage breakdown. Meanwhile, it is equipped with convenient functions such as remote control rod operation, acousto-optic alarm, and automatic test time control. The operation interface is simple and intuitive, making it suitable for both batch testing scenarios where production line workers can quickly get started, and refined testing needs during the R&D phase in laboratories. It is an ideal insulation and withstand voltage testing tool that balances safety, accuracy, and ease of use.
