LCD Monitor Internal Supply
September 12, 2005
13 Line Transient Testing
The power supply was tested for 1.2/50 µsec common mode and differential mode line
surge at 230 VAC, full load. The supply was mounted on a metal plate, and the output
was monitored with an LED to detect any output interruption. The power supply was
deemed to pass a test if it withstood the surge with no output interruption.
