2.3 ADVANTAGES OF PURE SINE WAVE INVERTERS
• The output waveform is a Sine Wave with very low harmonic distortion and cleaner
power like Utility / Grid supplied electricity.
• Inductive loads like microwaves, motors, transformers etc. run faster, quieter
and cooler.
• More suitable for powering fluorescent lighting fixtures containing Power Factor
Improvement Capacitors and single phase motors containing Start and Run Capacitors
• Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV,
fax and answering machines, etc.
• Does not contribute to the possibility of crashes in computers, weird print outs and
glitches in monitors.
2.4 SOME EXAMPLES OF DEVICES THAT MAY NOT WORK PROPERLY WITH
MODIFIED SINE WAVE AND MAY ALSO GET DAMAGED ARE GIVEN BELOW:
• Laser printers, photocopiers, and magneto-optical hard drives.
• Built-in clocks in devices such as clock radios, alarm clocks, coffee makers, bread-mak-
ers, VCR, microwave ovens etc. may not keep time correctly.
• Output voltage control devices like dimmers, ceiling fan / motor speed control may
not work properly (dimming / speed control may not function).
• Sewing machines with speed / microprocessor control.
• Transformer-less capacitive input powered devices like (i) Razors, flashlights, night-
lights, smoke detectors etc. (ii) Some re-chargers for battery packs used in hand power
tools. These may get damaged. Please check with the manufacturer of these types of
devices for suitability.
• Devices that use radio frequency signals carried by the AC distribution wiring.
• Some new furnaces with microprocessor control / Oil burner primary controls.
• High intensity discharge (HID) lamps like Metal Halide Lamps. These may get dam-
aged. Please check with the manufacturer of these types of devices for suitability.
• Some fluorescent lamps / light fixtures that have Power Factor Correction Capacitors.
The inverter may shut down indicating overload.
• Induction Cooktops
