NORMAL OPERATING CONDITION
DescriptionINFOID:0000000006257122
Because of modified sine wave output, the AC 120 V out
let may not operate normally for electric appliance of
which electric power consumption is 150 W or less.
Electric appliances requiring a large amount of electr ic power consumption at startup (e.g. CRT-based TV,
power tool)
Measuring instruments for data requiring accuracy (e.g. medical equipment, measuring instrument)
Microprocessor-controlled appliances (e.g. microprocessor-controlled blanket)
Noise may be caused in radio or TV, depending on an electric appliance.
