Brief introduction
ZC9900 series AC and DC withstand voltage insulation tester is a high-performance tester using brand-new technology. Its unique current protection function and high-precision output voltage enable the instrument to provide more accurate and faster tests while ensuring safety. The maximum 8 channels of withstand voltage output can better meet the all-around requirements of customers! ZC9900 series withstand voltage testers are mainly used for the safety performance testing of instruments, equipment, and components!
Performance characteristics
- ZC9901 is a single-channel high-voltage tester
- ZC9904 is a 4-channel high-voltage scanning tester
- ZC9908 is an 8-channel high-pressure scan tester
- Test function AC/DC/IR
- Display: large LCD display with a display resolution of 240×64
- AC voltage output: 50V-5kV, AC current: 30mA
- DC voltage output: 50V-6KV, DC current: 10mA
- Wide measuring range of insulation resistance: 1MΩ-50GΩ
- Ground connectivity test GC (optional function)
- Programmable leakage current upper and lower limit setting
- IR, DC test fast discharge function
- 99 steps to store data
- Good electric shock protection function: when the leakage current to the ground is greater than 0.5mA, the ground failure protection function is quickly triggered to effectively protect the external leakage and avoid accidents.
- Standard RS-232 standard communication interface, optional GPIB
