SKYTRONIC INVERTERS
An Inverter is an electronic device that converts low voltage DC (Direct Current) from a battery or other power
source to standard 230 Volts AC (Alternating Current) household power.
The Inverter converts power in two stages. The first stage is a DC to DC amplification which raises the low voltage
DC at the inverter input to 290 Volts DC. The second stage is the actual inverter stage which converts the high
voltage 290 Volts DC into 230 Volts AC.
The DC to DC stage uses a high frequency power conversion technique that eliminates the need for bulky
transformers found in more traditional inverters. The benefit of this is a significant reduction in size and weight.
The inverter stage uses advanced power MOSFET transistors in a full bridge configuration, which means that the
inverter has a much stronger load handling capability.
A power inverter converts DC power into conventional AC power which can run all kinds of household products
such as: kitchen appliances, microwaves, power tools, TVs, radios, computers and more. You just connect the
inverter to a battery, and plug your AC devices into the inverter and you've got power on the go.
The power inverter draws its power from a 12 Volt or 24 Volt battery, or several batteries wired in parallel. The
battery will need to be recharged as the inverter draws the power out of it. The battery recharges by running the
automobile motor, gas generator, solar panels, or wind and not with the power inverter. During blackouts, an
inverter can be used for emergency power by use with a car battery with the vehicle running and an extension cord
running into the house, where you can then plug in electrical appliances.
Using the SkyTronic 230V inverters
The SkyTronic range of inverters transform 12/24V battery voltage into 230V mains voltage, thus enabling you to
use your domestic equipment everywhere you want e.g. on camping, on a boat, in your car, etc. The regulated
output voltage makes the inverters suitable for use with sensitive devices such as TV sets, video and audio
devices, PCs or laptops and many more.
General features of SkyTronic inverters
•
high performance at low heat production
•
50Hz stable output frequency
•
regulated 230V output voltage
•
protection against short circuit and overheating
•
with SkyTronic battery protection system. If the battery voltage drops to 10.3V (21V for 24V batteries) the
inverter emits an alarm signal. If the battery voltage drops even further, the inverter shuts off automatically.
This advanced protection system avoids to over discharge the battery.
WARNING
SkyTronic inverters supply an output voltage of 230V which is as dangerous as the domestic mains voltage!
Therefore only use double-insulated devices and replace immediately leads that are in bad condition. Don’t expose
the inverters to humidity and place them in a well ventilated area. The inverters with an earth connector can be
connected to a grounding point such as a metal part of a boat or the car chassis.
Rechargeable Appliances:
CAUTION:
Certain rechargeable devices are designed to be plugged directly into an AC socket to be recharged.
These devices may damage the devices or POWER INVERTER. When first using a rechargeable device, monitor
its temperature for 10 minutes to ensure that it does become abnormally hot. This abnormal heat indicated that the
device should not be used with this POWER INVERTER.
Important!
Under full load, high current is flowing through the battery cables. Therefore it is recommended to use only the
supplied cables and no extension cables in order to avoid unacceptable voltage losses. If necessary, use an
extension cord in the 230V circuit to the connected unit. To comply with the legal standards, the inverter may only
be used with the supplied low voltage cables. Do NOT extend them.
The connected battery must be in good condition and fully charged. After some time, it may be necessary to start
the car or boat in order to recharge the battery. At that moment, the inverter must be switched OFF beforehand in
order to avoid damage due to excessive battery voltage.
On/off switch
Connect the inverter to the battery (red is positive, black is negative). Make sure that all connections are of good
quality. First switch on the inverter and afterwards the unit to be powered. Switch off in reverse order.
Thermal protection
All SkyTronic inverters are protected against thermal overload. If the temperature of the inverter rises above 65°C,
the protection circuit is automatically activated and the unit is switched off. First switch off the connected unit and
