OWNER’S MANUAL Pro-200W, Pro-400W POWER INVERTERS
IMPORTANT INFORMATION INVERTER BASICS Important Information About Your New WHISTLER Inverter. Notes: 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).
INVERTER BASICS Don’t Push It. Although your WHISTLER 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-400W watt model has a maximum continuous rating of 400 watts.
OPERATION Making the Connection. This inverter is designed to connect to your 12 volt battery using the lighter socket plug or by the supplied battery cables (for appliances over 150 watts, 400 watt model only). 1. 2. 3. 4. 5. Make certain that the inverter rocker switch is in the OFF (O) position. Connect the lighter plug or hardwire cables to the power input terminals at the rear of the inverter and tighten the screws to make a secure connection. Do not use tools to tighten these screws.
OPERATION • Pro-400W watt model - If the supplied cables are too short to allow for placement of the inverter in a desired location, the inverter may be connected to the power source using a #8 wire, up to 12’. Use #4 wire for longer lengths. The steps outlined for making the connection and the related safety precautions remain unchanged. 7. Turn the inverter rocker switch to the ON (I) position. The LED Indicator Light should glow GREEN confirming that there is power running to the inverter. 8.
ADDITIONAL FEATURES OPERATION does blow, turn off and disconnect the appliance or equipment from the inverter immediately, repair the related problem and replace the fuse(s). The internal fuses are replaceable, however only electronically knowledgeable people should attempt fuse replacement. Note: • Make certain to correct the source of the overload which caused the blown fuse before turning your inverter back ON (l). The Power Source.
CARE AND MAINTENANCE ADDITIONAL FEATURES 2. Low Battery Voltage Alarm/Shutdown Protection a) When the input voltage from the 12 volt power source drops below 10.5 volts, an audible tone will be heard. This is the low battery voltage alarm. b) The inverter will automatically shut down when the input voltage drops below 10 volts. This protects the battery from completely draining.
OPERATING PRINCIPLES For You Technical Types. 1. Basic Operating Principles: WHISTLER inverters work in two stages. During the first stage, the DC to DC converter increases the DC input voltage from the power source (e.g. a 12 volt battery) to 145 volts DC. In the second stage, the high voltage DC is converted to 110 volts (60 Hz AC) using advanced power MOSFET transistors in a full bridge configuration. The result is excellent overload capability and the capacity to operate difficult reactive loads.
OPERATION SUMMARY • • • • • This inverter is designed to be connected to the power source with the supplied cables or with #8 wire up to 12’ Use #4 wire for longer length. When utilizing the supplied cables do not attempt to modify or lengthen them. Always make certain that the power cable terminal connections Negative (-) to Negative (-) and Positive (+) to Positive (+). Check these connections frequently to ensure that they are secure.
