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 -40oC 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.
