Notes

All unspecified parameters are measured at 230VAC input, full load, 25°C unless noted.
Ripple noise measurements use a bandwidth of 20MHz with 12-inch twisted-pair wires and parallel 0.1μF + 47μF capacitors.
Derating is required for low input voltages; refer to derating curves.
EMC testing requires a 1mm-thick steel plate (360×360mm).
