- Technical functions
1. Input voltage: 380V for control; 3KV for transformer
2. It can monitor voltage and current at HV side, and current and voltage at LV side
3. Protective function: zero, over current and over voltage protection
4. Measurement meters : 1.0 grade;
5.)Functions are as folowing:.
- Withstand time to automatical step-down function
- Withstand time adopts digital-display timer. When it reaches withstand time, system will step-down automatically
- Zero switch on and zero step-up function: There is zero–limit function. If regulator is not at zero, HV output button can’t switch on, in order to ensure step-up is from zero. Regulaotor.
- Over current function: There is electric over current relay, anti- interference is strong, operation is fast, which avoid damage from over current.
- Over voltage protection function: There is electric over voltage protective board, it is fast and reliable; over voltage protection setting is regulated by manually, displayed by digital. It is intuitive, convinient and accurate..
- Real-time monitor function for all test date: It can monitor voltage and voltage at HV side, and current and voltage at LV side
- Automatic test aided computer intelligence system..
- Manual testing on software in computer.
- Automatic test with each setting value for Voltage and time ;
- Saving function for each Test setting .
- Test Report printing
- Computer Hardware should be use the latest Industrial model.
- Display monitor should be 19” or above size..
remark: wuhan fanke company can produce so many models according test objects condition and test usage.
