Power Conditioners incorporate a low impedance isolation
transformer, as well as a surge diverter and power line filter to
eliminate noise, spikes
and transients before they have a chance to wreak havoc on your POS
■ Product sizes range from 78 watts to 2500 watts capacity
■ Suitable for use with instrumentation, analyzers, Point-of-Sale (POS)
systems, ATMs, security systems, etc.
■ Prevents hardware destruction, component degradation and operational
■ Red flashing LED warns if the AC outlet is missing its input
■ Surge Let through voltage is less than 10 volts normal mode and less
than 0.5 volts neutral-to-ground
Load Power (VA)
All power supplies include a line cord and rear mounted device outlets.
Line conditioners are sized according to the maximum continuous amount
of current, measured in Amps (A), that they can supply at the rated
Voltage (V). This is expressed in Volt-Amps (VA), or watts (1 VA =
1 watt). A 120 Volt device rated at 1 Amp would be (120 x 1 = 120 VA) or
120 Watts. Most devices have a plate or the rated voltage and current
stamped on the device generally near where the power plugs in. For
devices with external power supplies, use the ratings printed on the
As an example let's look at two common components used in a POS system
- a touch terminal and a receipt printer.
Terminal - Find the label on the terminal and note the Amps
required. In this case the amps are given in a range depending on the
supply voltage. For 120 Volts the Amps would be about 0.65A. Multiple
the volts with the amps to get the VA required, (129 x 65 = 78 VA). Find
a conditioner that is rated at this VA or larger.
Receipt Printer - The Epson TM-T88V receipt printer uses a separate
PS-180 120 volt power supply. Find the input amps used, in this case 1.3
A. Multiple the volts with the amps to get the VA required (120 x 1.3 =
156 VA) Find a conditioner that is this VA or larger.
If using a
single conditioner for multiple devices, just add the VA values together
(78 + 156 = 234 VA) in the above two examples)
