Project Description
HT9951B withstand voltage and insulation tester is designed to finished photovoltaic modules. They also are be used to wet leakage testing of modules. The maximum output of the instrument is DC 10kV and the maximum test range of insulation resistance is 99GΩ. The instrument is equipped with a standard RS232 serial port, which can realize data transmission and collection functions
The testers are complied with photovoltaic standards IEC61215, IEC61730.
- Test voltage, leakage current, and test time are displayed simultaneously
- Multiple trigger modes
- Continuously adjustable output voltage
- Arbitrarily set the voltage rise time, test time, test waiting time
- Sound and light alarm function
- Arc detection function, ARC alarm
- Product program can be upgraded via U disk
- Rich interfaces
