accommodating starting surge for motors, microwave use
and aggressive use of power tools.
The battery input is via internal 5mm stud terminals. The unit
may be turned off and on remotely, by a low current control
input to a 6.35mm spade terminal. An earth stud is fitted on
the outside of the box for chassis connection.
BATTERY SELECTION: Only heavy duty (high discharge
rate) batteries are suitable as a power source. Fully sealed
types should be used in enclosed spaces (especially inside
the home). Ordinary car batteries are only suitable in well
ventilated areas.

SWITCH SELECT 230V / 115V AC OUTPUT
BUILDING SITE USE (110V RANGE).
RUNS SMALL MICROWAVES AND FRIDGES.
HIGH OUTPUT POWER IN COMPACT SIZE.
HIGH CONVERSION EFFICIENCY.
REMOTE ON / OFF CONTROL FACILITY.
GENERAL DESCRIPTION. Small floor mounting converters,
available with other input and output voltages, generating
mains level power, capable of powering most small office or
laboratory equipment from any 12 or 24 volt battery system
They are particularly aimed at small refrigerators and
microwave ovens.
Dual outlet sockets are fitted to the unit (see model numbers
for details). The input may be isolated from chassis The
output is isolated via a safety barrier from the input.
The output is a stepped odd function wave AC output of
nominally 230V/115V RMS Switchable, with a peak voltage
appropriate to mains, corresponding to a quasi sine wave.
This output, suitable for switched mode supplies, is required
for machines employing a mains transformer, making it
suitable for almost all equipment.
The specification allows for up to 700 watts of continuous
power to be used, with short surges up to 1200 watts,

CAUTION: This adaptor is supplied on the basis of the user determining the suitability for the purpose for which it is to be used. Do not use in a
moving vehicle without the consent of the vehicle maker. Do not use for aviation or marine applications without written agreement. Do not use for
life dependent applications. The negative input lead is connected to case and output ground making the unit suitable only for negative earth systems.
