working in stand-by mode. The board operates in burst mode when both the output loads

are reduced to zero and the output voltages still remain regulated.

Stand-by input power

At the input voltage of 120Vac, a minimum load of 100mA is needed to keep the total input

power consumption to be less than 1W.
