The Alpha APX-100W Non-standby Power Supply provides conditioned power to signal amplifi ers
in cable television and broadband distribution systems. The transformer is mounted directly to the
chassis, and supplies the load with current-limited, regulated AC power, that is free from spikes,
surges and other forms of power line transients. Once AC power enters the module, it is converted to
a “quasi” square wave and regulated at the required output voltage.
The APX-100W is extremely effi cient, with a typical effi ciency rating of 90%, and is designed to be
either pole or wall-mounted. This product, along with the entire line of Alpha power products, is one
of the most rugged, reliable, and versatile power supplies available. Alpha Technologies, recognized
as an international market leader in the fi eld of backup power, offers complete technical support
and prompt, reliable service to ensure that your power supply continues to provide you with years of
trouble-free operation.
