PID TESER /PID POWER SUPPLY UNIT
Functional features
l The photovoltaic module frame end is grounded, which not only simulates the actual situation, but also prevents the potential danger caused by the frame high pressure in the testing process;
l For each component, the 4-wire test method is adopted, 2 high-voltage wires and 2 ground wires. The high-voltage wires are connected with the components internally through the junction box, and the ground wires are connected with the frame or connected in other effective positions.
l Each channel is independent of each other, the polarity of the voltage of each channel and the time can be set separately;
l Voltage, leakage current, insulation resistance display at the same time;
l Real-time monitoring of voltage, leakage current, insulation resistance curve;
l The screen shows the test situation and records the data in the test;
l All monitoring data can be exported in Excel, CSV, and other formats
l Enter the component serial number, test period, and test name to query historical data and curves
l Alarm parameters are set separately, such as overcurrent alarm and undervoltage alarm.
