            Switches among CV, CC, and Vds modes,
            Switches V rms/p-p, turns on/off high voltage output
            Shock Guard Function
            The high voltage output is cut off when the CCFL test
            bench cover is opened.
            Withstand Voltage Between power input pairs and others: AC 1500V,
            1 minute
            Insulating Resistance Between power input pairs and others: 50Mω or
            higher at DC 500V
