EN60950
UL/cUL60950 Description Pin Configuration The PTB48600A is one of a series
of isolated DC/DC converter modules
that provide a pair of complementary
supply voltages for powering line-driver
ICs in xDSL telecom applications. These
modules operate from a standard telecom
(-48 V) central office supply and can
provide up to a 85 W of power in a balanced load configuration.
The A-suffix module (В±5 V) is designed
to power the line driver ICs for the AC-7
ADSL chipset. It will also power any
other applications that require a complementary supply with relatively balanced …
