1.0 INTRODUCTION
The T240 Autotransformer is designed to step-up 120 volt AC to 240 volt AC
or to step-down 240 volt AC into two 120 volt AC circuits. The T240 contains
two identical windings that can be used to step-up, step-down, or balance the
output voltage of an AC power source (such as an inverter, generator or
conventional AC source) to an AC load. The unit is sized to take advantage of
Trace Engineerings inverter/charger line. The exceptionally high efficiency of
the T240 Autotransformer makes it ideal for voltage conversion from an inverter,
generator or conventional AC source.
The T240 Autotransformer utilizes a highly-efficiency transformer constructed
of high temperature materials and M-6 grade steel laminations, meeting UL
Class-H standards.
The unit is housed in a powder coated, steel enclosure, suitable for indoor
installations and contains knockouts for 3/4 inch and 1 inch conduit connections
and additional breakers. One 25 amp dual breaker is supplied with the T240.
Up to six additional Square D QOU breakers can be added for additional input/
output wiring protection and control.
