certain devices (few examples given below) may malfunction when powered from
modified Sine Wave. check with the manufacturer of the device for suitability of
powering with modified Sine Wave:
• Devicesutilizingzerovoltagecrossingfortimingcontrol:Someclocksusedincon-
sumer electronic items (will not keep accurate time)
• DevicesusingmodulationofRFsignalsonAClinesduringzerocrossinge.g.X-10
System for Home Automation
• DevicesutilizingTriacbasedphasecontrolfortransformerlessvoltagestepdown
e.g.:
• Smallbatterychargersforhandtools,flashlights,night-lights,shaversetc.
• Variablemotorspeedcontrolinhandtools
• Lightdimmers
• Temperaturecontrollerse.g.TemperatureControlledElectricBlankets
• Devicesusinghighcapacitancebasedvoltagemultipliersforgeneratinghigh
voltage (will create very high surge currents) e.g.:
• PhotographicStrobeLights
• LaserPrinters
measuring modified Sine-Wave voltage with a “true rmS” voltmeter
As mentioned above, Modified Sine Wave voltage is a type of square wave that has an
rMS (root Mean Square) value of 115 VAC in this inverter. A general-purpose AC voltme-
ter is calibrated to accurately measure the rMS value of a Pure Sine Wave and NoT of a
Modified Sine Wave. If this general-purpose voltmeter is used to measure Modified Sine
Wavevoltage,itwillindicatealowervalue(96VACto104VAC).Foraccuratelymeasuring
the voltage of a Modified Sine Wave, use a voltmeter which is designed to measure “True
RMSValues”likeFluke87,Fluke8060A,Fluke77/99,Beckman4410etc.
