output
Output and PE SGND of the 12 V output and the PE are short-circuited inside the PSU.
Leakage current 0.75 mA (230 V AC/60 Hz), 0.875 mA (264 V AC/60 Hz)
Insulation ≥ 10 megohms. The insulation resistance of the primary circuit to the
resistance secondary circuit and that of the primary circuit to PE should be at least 10
megohms in the following conditions: V
(non-condensing)
Input to output must meet the reinforced insulation requirements after the output ground is disconnected from
the PE.
