Transformer capacity is rated in Volt-Amps (VA) which is generally the
same as wattage (Watts). Most loads are labeled with their proper
operational voltage (Volts), current (Amps), frequency (Hz), and wattage
(Watts or VA).
To compute a load’s VA requirements, multiply its rated voltage (Volts) by
its rated current (Amps). This information is usually found on the back of
the load - on its nameplate. If you cannot locate the labeled voltage and
current (to calculate the VA), use the wattage (Watts), if shown.
Exceptions are fluorescent lights, neon signs, gas discharge lamps,
specialized electronic controls, etc which require a transformer with a VA
capacity 1.5 times the wattage rating, if the volts and amps are not
shown. Select a transformer with a VA rating equal to or larger than the
VA found on the nameplate of the load.
Using a transformer with a smaller VA capacity than that required by the
load will cause the transformer to overheat and eventually burn out .
All MAXINE transformers are precision wound and insulated with the latest
hi-tech, insulating materials. The core laminations are of high grade
annealed silicon steel, designed to keep heating to a minimum. All
transformers are impregnated with a modified polyester heat cured varnish,
which seals the transformer, thus protecting the electrical windings from
moisture and contamination. Metal housings are baked enamel finished, and
all MAXINE transformers are thoroughly tested, twice, and thoroughly
inspected to ensure top quality. The result of this use of superior
materials, advanced design, and complete 100% testing is long,
trouble-free transformer life.
All MAXINE transformers are indefinitely guaranteed to be free of defects
in materials and workmanship. When operated properly, our transformers
will last a lifetime* and comes with warranty*. In the event of a defect,
Shah Electronics will repair or replace a defective unit free of charge,
pending our inspection, if returned to the factory, prepaid. Of course,
transformers that have been misused by over voltage or overload are not
covered by this warranty, since such misuse will decrease the life of the
transformer, causing it to overheat and eventually burn out.
