]]>The post EVSE Test Box appeared first on Oxa Technologies.
]]>This test box allows a more complete manually stepping through the states used in a J1772 technology charging station (EVSE). It has a test function to verify the operation of the Proximity Pilot(PP) switch that is controlled by the connector latch. It also can simulate a ground fault.
Input, output ports is available out of the box. User can connect very easily and can use.
Fully covered and fully isolated for users. Transient protection and high current protection are available and neutral fully isolated.
It can be use with very high frequency. All products selected durable.
Very low cost compare of the other product.
It can connect parallel for power sharing.
After the connection of your plug, trigger switch functionality, and capability:
Step A – Disconnected.
You can check the ground connection. If you see any voltage on the banana connector you can say that there is a connection fault. And you should not use the device for your car. You can see normal device tests from the video.
Step B – Connected
CP voltage change by device, and device connected light can see from your EVSE. If you measure any voltage from the banana connector you can say that there is a problem. After that, you can check your EVSE product connections.
Step C – Charging
This step will trigger the EVSE, and you will see the voltage from the banana connector. If you do not see any phase voltage you can say that there is a problem with your EVSE.
Also, the tester will provide the fuse for each phase. When you use the tester for a load simulator it will protect your device from unexpected problems.
