POWER INVERTERS

FEATURES

FEATURES

1. Three 110 AC Outlets

2. Remote Operation Jack

The inverter is designed to be operated from a
remote location via a WHISTLER Remote Control
Switch (P/N Pro-RS01) which plugs into this socket.
This optional accessory is available through
WHISTLER or your WHISTLER dealer.

3. USB Power Port

This port is always on and independent of the
inverter’s on/off switch.

4. On/Off Switch

Turns the unit On/Off.

5. Digital Power Meter

6. On/Shutdown Indicator Light

The LED will illuminate GREEN when the inverter is
powered in normal conditions. This light will turn RED
and the inverter will automatically shut down (except
low voltage alarm) when any of the following
problems occur:

• Short Circuit Protection.

down until the short is removed.

• Low Voltage Alarm. An alarm will sound when the
voltage from the battery discharges to 10.5+/-0.5

volts DC. This is an indication that the battery needs

to be recharged.

• Over Voltage Protection. The inverter will turn itself
off when the input exceeds 15.5+/-0.5 volts DC.

• Under Voltage Protection. The inverter will turn
itself off when the input is less than 10.0+/-0.5
volts DC.

The inverter will shut

• Overload Protection. The inverter will turn itself off
when the continuous draw or the surge draw of the
equipment being operated exceeds the maximum
power rating for the inverter.

• Thermal Protection. The inverter will turn itself off
when the internal temperature exceeds safe design
parameters.

7. Cooling Fans

8. Power Input Terminals

(Observe proper polarity)

Note:

In the event of an automatic shut down or continuous
audible alarm, turn the inverter OFF (O) until the source of the
related problem has been determined and resolved.

IMPORTANT INFORMATION

Important Information

This manual will provide you with directions for the safe
and efficient operation of your Whistle Power Inverter.
Read the manual carefully before using your new Whistler
inverter and keep the manual on file for future reference.

Important Note:

and safety features must be carefully reviewed and
thoroughly understood prior to using the inverter. Failure
to do so may result in damage to the inverter, equipment
or serious personal injury.

Notes:

Your Whistler inverter is designed to operate from a 12 volt
power source only. Never attempt to connect your
Whistler inverter to any other power source, including any
AC power source.

• 110 volts can be lethal. Improper use of your Whistler
inverter may result in property damage, personal
injury or loss of life.

• Do not connect the inverter’s output to any other
power source.

About Your New Whistler Inverter.

Each of the following operating procedures

INVERTER INFORMATION

Getting Started

Power equipment and appliances which operate with motors
or tubes require an initial surge of power to get them up
and running. This power surge is referred to as the "starting
load" or "peak load." (By comparison, electrical devices such
as standard light bulbs do not require a large starting load.)
Once the equipment or appliance has been powered up, it
settles down to a slower pace and requires far less electrical power
to operate. This lower power requirement is referred to as
the "continuous load."

In order to ensure that the capacity of your Whistler inverter
is sufficient to meet the required start up load, you must first
determine the power consumption of the equipment or
appliance you plan to operate.

Power consumption is rated either in wattage or amperes,
and information regarding the required "watts" or "amps"
generally is stamped or printed on most appliances and
equipment. If this information is not indicated on the appliance
or equipment, check the owner’s manual. Contact the

appliance or equipment manufacturer to determine if
the device you are using (TV’s, battery charger, computer,
etc.) is compatible with a modified sine wave.

If the power consumption is rated in amps, multiply the number
of amps by 110 (AC voltage) to determine the comparable
wattage rating. Induction motors may require 2 to 6 times
their wattage rating to start up.

For further information on the fundamental operating
principles of Whistler inverters and related technical
data, see "Technical Operating Principles."

INVERTER INFORMATION

INVERTER INFORMATION

Don’t Push It.

Although your Whistler power inverter has the capacity to
provide power output (excess current) equal to approximately
two times its rated wattage capacity for a very brief period,
it is designed to operate equipment and appliances with
start up load wattage ratings no higher than its own maximum
continuous wattage rating.

For example, the Pro-1200W model has a maximum
continuous rating of 1200 watts. Although this model has
the capacity to briefly provide more than its continuous
power (that is, excess current), it is designed to operate
equipment and appliances with start up load requirements of
1200 watts or less.

Consequently, if the start up load rating of your equipment
or appliance is slightly higher than the maximum continuous
rating of the inverter, the inverter will attempt to start loads
above the continuous rating.

Some refrigerators, freezers, pumps and other similar
equipment and appliances require very high start up loads
to operate. Before attempting to power up this type of
equipment or appliance, make certain that all connections
have been properly made and that the power source is fully
charged.

To determine whether your inverter will operate a particular
piece of equipment or appliance, run a test. The inverter is
designed to shut down automatically in the event of a

power overload. Testing appliances and equipment with
start up load ratings comparable to your inverter wattage
rating will not damage it.

If a piece of equipment or an appliance will not operate,
first confirm that the inverter has been properly connected
to the 12 volt power source (See "Making The Connection").
If all connections have been properly made, turn the inverter
rocker switch ON (l), OFF (O) and ON (l) again in quick
succession. If this procedure is unsuccessful, it is likely that
the inverter does not have the required start up capacity or
your battery supply isn’t large enough to operate the
equipment or appliance in question.

Selecting the Optimum Power Source.

Operating the inverter for extended periods combined with
a high continuous load demand may result in excessive
power drain from the battery. Therefore, the reserve capacity
of the battery you select to power the inverter is an
important consideration.

The potential power drain can be estimated by calculating
the reserve power ("amp-hour"or Ah) of the battery and
the amps required by the inverter to meet the continuous
load demand of the equipment or appliance being
operated.
