1. INTRODUCTION
Your new inverter is one in a series of the most advanced DC to AC inverters available
today. With proper care and appropriate usage, it will give you years of dependable service
in your car, truck, RV or boat.
The inverter supplies continuous 230V, 50Hz power via a standard 3-pin socket whenever
and wherever it is required. The inverter is capable of running a range of household
appliances, including colour TV’s, TV/VCR combinations, laptop computers, camcorders,
cellular phone, power tool chargers, lamps etc., depending upon the rating of the converter.
Added safety features include automatic shutdown and a low battery alarm - to avoid the
possibility of damaging your battery.
2. CONTROLS. INDICATORS AND CONNECTORS
Two LED’s are provided on the front panel.
• The
GREEN
LED illuminates when the converter is connected, switched ON, and working correctly.
• The
RED
LED , when illuminated, indicates that the inverter has shutdown - from overload,
over voltage or over temperature.
230V Power is provided via a standard 3-pin socket.
An ON/OFF switch turns the inverter circuitry On and Off. The switch is used to force reset
the inverter circuits.
The back panel provides DC connectors, either battery clamps or cigar lighter connector.
3. HOW YOUR INVERTER WORKS
The inverter converts a 12V direct current - from a battery or other power source, to a
230V 50Hz AC (alternating current) output.
3.1. Principle of Operation
The inverter converts power in two stages. The first stage raises the low voltage DC
input to high voltage DC. The second stage is the actual inverter stage that converts
the high voltage DC into AC. See figure 1.
The inverter stage uses advanced power MOSFET transistors in a full bridge
configuration. This ensures excellent overload capability and the ability to operate
reactive loads such as lamp ballasts and small induction motors.
