<1 watt input power spec (+5 V standby loaded to 0.5 W and main supply off at
115 VAC input). Input power is 0.86 W.
If interconnect board is used, subtract 0.07 W (standby LED consumption) from
input power measurement.
Blue Angel (240 VAC input, Main convert inhibited, +5 V standby loaded to
2.5 A). Input power is 4.1 W.
