  • The tech spec indicates power input requirements as 100-240V AC, 50-60Hz; input current: 0.2 amp

    Power (watts) equals voltage times current.

    With 100 volts, the power input is about 100V x 0.2amp which equals 20 Watts.

    With 240 volts, the power input is about 240 x 0.2 amp which equals 48 watts.

    I would think the 0.2amp is the maximum input current so I would bet these numbers will probably be less on average or about half in reality when operating. However, for safety reasons, the larger numbers should be used in design of electrical wiring.
