DESCRIPTIONS
The 300WFR series 3 watts power modules are high
efficiency, low profile dc-dc converters that operate over a wide
input voltage range of 4.5 - 9 VDC, 9 - 18 VDC, 18 - 36 VDC and 36
- 72 VDC and provide precisely regulated output voltages of
3.3V, 5V, 12V, 15V, ±5V, ±12V and ±15V.
The -25oC to +71oC operating temperature range makes it
ideal for data communication equipment, mobile battery
driven equipment, distributed power systems, telecommunication
equipment, mixed analog/digital subsystems, process/
machine control equipment, computer peripheral systems
and industrial robot systems.
