Modified Sine Wave
The Inverter can only power AC appliances which are compatible with a Modified Sine Wave
(non-sinusoidal).
Note: Only multimeters identified as “TRUE RMS” will read Modified Sine Wave voltage accurately.
Modified Sine Wave power is suitable for
most AC devices and power supplies used
in electronic equipment, transformers, and
motors.
Note: Do not use to power sensitive
devices such as medical equipment.
Some audio equipment may perform poorly if run
on Modified Sine Wave power. Some appliances
can be damaged if used with this Inverter if they are not compatible with a Modified Sine Wave
unit. Do not use with the following appliances:
• Electronic appliances which modulate RF (radio frequency).
• Chargers for batteries.
• Metal Halide arc lamps.
• Incompatible speed controllers in fans, power tools and kitchen appliances.
Note: if you are not sure if your appliance is compatible with this Modified Sine Wave Power
Pack, check with the appliance manufacturer
DC APPLIANCE COMPATIBILITY
The Power Pack can power a 12VDC auto, RV, marine, or other portable item that draws
12 amps or less. The lower the amount of watts the appliance uses, the longer the Power
Pack can power it before needing to be recharged.
The Power Pack has two 12VDC Outlets. The total load from both outlets must not exceed
12 amps or 144 watts. Calculate the total wattage needed to run the appliances before operation.
You do not need to calculate startup or surge wattages.
To calculate the size of the load you plan to use with the Power Pack, use the following formula:
Amps x Volts = Watts
For example, if you have two appliances whose running amps total 7 amps, you will need 84 watts
of power (7 amps x 12V = 84 Watts) to run the items. This figure is within the capacity of the unit.
INVERTER OVERLOAD INDICATOR
The Power Pack is equipped with an Inverter Overload Indicator Light which will illuminate when
the battery reaches 11.3V, signalling that the battery is low and the unit will soon shut down to
prevent damage to the battery.
If this happens, disconnect any loads in use and recharge the Power Pack.
Note: When the battery reaches 9.4V, power to the Outlets is automatically shut down.
