POWER INVERTERS

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

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.
