Insulation Resistance I/P-0/P, I/P-FG, 0/P-FG: 500VDC 100M Ohms. . Package List: 1 x Power Supply Converter Note: 1. All parameters are measured under rated voltage 220VAC input, rated load, ambient temperature of 20 degrees Celsius, and humidity of 70%. 2. Accuracy: Including setting error, line adjustment rate, load adjustment rate, etc.3. Ripple Test: Connect the power supply and the load with a 30CM long stranded wire, connect 0.1u and 47u capacitors at the load end, and measure it with a 20Hz oscilloscope at the load end. 4. Line Regulation Rate: Under rated load, the input voltage is measured from low to high change. 5. Load Regulation Rate: The measured output is measured from 0% load to 100% load change. 6. Each channel can output the maximum current, but the sum of the total load cannot exceed the maximum output power.
