Standby Input Power
The input power with standby loaded to 0.5 W and main supply off at 115 VAC input is
0.91 W.
Note: when measuring for less than 1 W input power spec and output interconnect board
is used, the yellow standby on LED on the board dissipates 0.07 W. This should be
considered part of the output loading.
Blue Angel
240 VAC input, main converter inhibited, +5 V standby loaded to 2.5 A.
Input power is 4.2 W.
