The Popular "Handy Mains" Inverter Series
The "Handy Mains" series of inverters produce AC mains power from a broad range of battery inputs and
some models have now been in production for over 10 years. We have a wealth of experience with inverters
and our designs reflect this, during their life time they have constantly evolved to meet the challenge of
powering most types of equipment, modern and old. With sales to five major distributors the ‘Handy
Mains’ has become one of the foremost inverters in the field.
With power ranges up to 2700W there is sure to be a "Handy Mains" to suit your requirements.

GENERAL: These small but powerful converters provide a source of stabilised low voltage
suitable for running many different items of equipment. Their output is ohmically isolated from the
system chassis and constant current limited. Continuous operation in current limit is allowed
making them suitable for battery charging. Connection to the system is by a ‘cigar’ plug (12 & 24V
Input) lead or just a flying lead (48V input), and output is by flying lead (5V - 15V units) or 2.5mm
concentric connector (18V - 48V units).
The converters are mainly designed for use with notebook computers that have two wire input.
These converters are current limited above a certain level of demand. The output isolation of the
converter from system ground ensures that earth currents do not flow.
CONNECTION:
Input: For 12V and 24V units, the converter just plugs into a cigar type socket, using the cable
mounted plug provided. Don't leave the converter plugged in when not in use. It will still slowly
discharge the battery. 48V input units must be directly wired to the 48V supply, fused at the battery
source with a 3.15A fuse. The input cable has a YELLOW sleeve fitted close to the case to identify
it. The RED wire connects to battery positive (+) and BLACK wire to battery negative (-).
Output: 15V output or below: Un-terminated cable. 18V output or more, 2.5mm ‘barrel’
connectors, centre positive. Red wire or White stripe positive, Black wire negative. The warranty is
not affected if the purchaser fits a different suitably current rated connector.
BATTERY DRAIN: These converters take about 1A at 12V, 0.5A at 24V or 0.25A at 48V for
every 10 watts of load. Input current may reach 10A (12V), 5A (24V), 2.5A (48V).

Specification Notes:
1) The main variation of output voltage with load is due to the resistance of the output cable (0.01
ohms). An internal potentiometer is available to adjust the output voltage to compensate.
2) The output current limit is deliberately made a function of unit temperature to maximise
delivered charge. Output current will fall, still within the quoted range as the unit attains working
temperature.
3) Case temperature change must be taken into account when calculating output variation.
4) The adapter is designed to run with a case temperature approaching 60C under heavy load
conditions.
SAFETY WARNINGS.
Ensure that the battery voltage is correct for the model. Do not reverse the polarity of the input voltage.
Use at least 2mm2wire to connect the converter to the battery. Thin wire will cause fire hazard.
Fuse Battery at source. The case is connected to the negative input (48V input versions floating).
Only operate the unit from a battery. Do not connect the unit to any other power source. For inside use only.
Do not expose to moisture. Do not cover. The unit will run hot when under elevated load.
Disconnect the battery before changing the fuse. Do not operate the unit with the cover off.
Turn off when not in use to avoid battery drain. Not to be used for life support.
Do not use in a moving vehicle without the vehicle manufacturer’s consent.
Do not use for marine or aviation applications without our written agreement.
This equipment is supplied on the basis of the user determining the suitability of use.
We reserve the right to change the specification without notice.

OTHER CONVERTERS IN RANGE
The range of converter products manufactured in the UK, by SMET Ltd., allow a broad range of battery
voltages to be converted to commonly required output voltages. These converters are suitable for powering
most domestic and professional electrical appliances that have a DC input. Wherever you are you can run
your laptop, power your CD/cassette player, charge your camcorder or simply charge batteries from your
main battery.
One of the most important things, when selecting the right converter, is to know the highest power rating of
the range of equipment you wish to run, and whether use is solely to power a device or to charge the battery
within a device. Converters have different short term and continuous power capabilities, which must be
matched with the equipment they are to run. Note that nearly all low voltage DC devices will have a power
plate stating the required input voltage and current and voltage polarity required. If you have any questions
with respect to choosing the right converter for your application call our Help Line on [phone] and
we will be happy to help you.
Smaller converters are fitted with an input plug to suit cigar lighter sockets, others intended for permanent
installation have short heavy wires for connection to the battery, with a third thin wire to connect to a low
current switch (termed ‘3 wire i/p’) for on/off control. Large converters have heavy duty studs. The outlets
come in a wide range to suit most appliances, be sure to tell us which connector and polarity you require
when ordering.
CAUTION: These adapters are supplied on the basis of the user determining the suitability of use.
