mThe 300FR series 3 watt power modules are specially
designed to provide low output ripple and tight regulation in
oa low-profile 24 pin DIP package. The series consists of 20
.cmodels with input voltages of 5V, 12V, 24V and 48V, and offers
regulated output voltages of 5V, 12V, 14V, ±12V and ±15.
UThe -25oC to +71oC operating temperature range makes it ideal
for data communication equipment, mobile battery driven
t4equipment, distributed power systems, telecommunication
equipment, mixed analog/digital subsystems, automatic test
instrumentation and industrial robot systems.
