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.

for data communication equipment, mobile battery driven

equipment, distributed power systems, telecommunication

equipment, mixed analog/digital subsystems, automatic test

instrumentation and industrial robot systems.
