Sine Wave Inverter
Sine
wave Inverter (or Sinewave inverter) units enable
conversion of a DC source, such as a battery, into AC
power which is the same as normal mains power. A sine
wave inverter has the advantage over a modified sine
wave inverter (sometime referred to as a quasi-sinewave
inverter) in that it produces a wave form which is smooth
in curve, not stepped or castellated. The waveform which
a pure sine wave inverter produces should not cause
any interference and is especially useful if the equipment
being run from it is telecommunications/radio equipment
or has a visual display such as a computer monitor.
 In
general industrial applications would demand a sine
wave inverter as a minimum specification where important
equipment is being run in an environment where only
a DC power source is available, this might be a -48Vdc
telecommunications cabinet where a monitor is required.
Such sine wave inverters are also popular in the leisure
market where a boat or caravan owner wishes to run a
TV or other appliances, but only has the battery of
the vehicle to run off. A sine wave inverter is perfect
under such conditions as it presents to the user an
AC waveform which is exactly how it would be if the
appliances were plugged into a socket at home.
There are a vast range of DC voltage inputs which the
sine wave inverter can accept, these are typically 12Vdc,
24Vdc, 48Vdc, 110Vdc and even 220Vdc. Simplypowersupplies.com
offer sine wave inverters at all of these input voltages
and with a wide range of power from 180W to 5kW in a
single unit. Typically we can offer a range of input
voltages which are about +/- 20% of the nominal input
voltages stated, the reason for this is the fact that
a batteries actual voltage will drop away as it discharges
its power, a sine wave inverter with a range such as
this will allow for this change in voltage and it will
not effect the output in any way.
For applications requiring higher power units which
have synchronisation built in can be wired in parallel
or in a redundant configuration for higher security.
There are also a number of different mechanical formats
which the sine wave inverters can be supplied in. Typically
smaller sine wave inverters will be chassis mount and
therefore can be screwed down to a base plate or even
to a wall or other surface. There are also floor standing
variants where the design will be more upright and these
would generally be larger units and may be used onboard
boats or other vehicles. Finally simplypowersupplies.com
can supply a selection of true sine wave inverters which
are suitable for mounting in standard 19” racks
which are common in industrial applications such as
power stations, manufacturing plants and offshore oil
rigs.
In addition to standard true sine wave inverter units
simplypowersupplies.com also offer units which include
a battery charger - referred to as combination charger/inverters,
and grid connect inverters for those who wish to export
power back into the grid.
Sine wave Inverter units can be supplied with 230Vac
output or as an option with 110/120Vac output for use
on-site or for powering appliances which are produced
for the US market.
