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