Notes
All unspecified parameters are measured at a 230VAC input, full load, and an ambient temperature of 25°C unless otherwise noted.
Ripple and noise measurements are conducted using a 20MHz bandwidth oscilloscope with 12-inch twisted-pair wires, terminated with parallel 0.1μF and 47μF capacitors.
Power derating is required for operation under low input voltage conditions; please refer to the standard derating curves for specific values.
EMC testing is performed with the power supply mounted on a 1mm-thick steel plate measuring 360×360mm.
