Notes:
1.All parameters, unless otherwise specified, are measured at an input voltage of 230VAC, rated load, and atemperature of 25℃c.
2.Ripple and noise voltage are measured using a 20MHz bandwidth osciloscope with 12-inch twin leads terminatedwith 0.1 ufand 47 uf capacitors.
3.Tolerance is the sum ofvoitaae setind error, voltade reaulation, andcurrent reaulation.
