Product Details
| Place of Origin | Jiangsu, China | Brand Name | Allwin | |
| Model Number | CS9950N | Power | Electronic | |
| Usage | Auto Testing Machine |
Product Description
- GOAL: check that all the touch accessible parts are properly connected to the protective earth connection.
- PRINCIPLE: Apply a current in between each metallic accessible part and the earth protection connection, then measure the voltage in between those two parts and check with the Ohmic law that the calculated resistance is lower than the value required by the standard. The DUT is not connected to mains!
- TEST CONDITIONS (according to the main standards):
♦ Current 10, 25 A AC or DC, or 2 x In
♦ Voltage from 6 to 12 volts AC or DC
♦ Resistance < 0, 1ohm, 0, 2 ohm or 0, 5 ohm
♦ Time > 5 s, 1mn or not defined
- Test current value: 5 to 32 A AC / Resistance value: 0.001 to 0.510 ohm
- Voltage drop-based judgment function
- Store the testing data automatically by the USB interface
Combined with CS9911N series hipot tester, CS9950N can do the hipot test simultaneously, which saves the test time. Our company provide the automatic test box.
The above picture shows the ACW hipot, DCW hipot, insulation resistance and ground resistance test simultaneously.
