1.3 Definitions
Quasi Sine Wave:
Quasi Sine Wave Inverters are sometimes called "modified sine wave inverters" or "modified square wave inverters."
Quasi sine wave inverters produce an AC output wave different from the power produced by the electric utility
companies and rotating generators.
Load Demand Feature and Load Demand Mode:
The Load Demand Feature is an energy conserving feature which allows the inverter to enter the ‘Load Demand
Mode’ whenever the inverter is ON and the AC load has been less than 5 watts for approximately 5 seconds. While
in the ‘Load Demand Mode’ the inverter does not produce 120 volts AC but instead produces pulses of 120 volts AC
which the inverter uses to look for a load at a one second rate. When an AC load greater than 5 watts is sensed, the
inverter will turn fully ON to produce a constant 120 Volts AC. The ‘Load Demand Mode’ is often also described as
‘stand-by mode’ or ‘sleep mode’. While in the ‘Load Demand Mode’ the inverter consumes approximately 140
milliamps of 12 volt DC power.
The Load Demand Feature can be turned OFF by setting Selector Switch 2 to the OFF position. This will cause the
inverter to remain fully ON, producing 120 Volts AC, whenever the inverter switch is ON and regardless of AC load.
It is desirable to do this when the device being powered draws less than 5 watts. With the Load Demand Feature
turned OFF and operating no AC load the inverter consumes approximately 1.8 amps of 12 volt DC power.
