OBSOLETE PRODUCT Contact factory for replacement model 3 WATT UNREGULATED WIDE INPUT RANGE DC/DC CONVERTER PWR72 FEATURES DESCRIPTION l Low Price l High Power Output: 3 Watts l Wide Input Voltage Range: 5VDC To 22VDC l Isolation Barrier 100% Tested Per UL544, VDE750, and CSA C22.2 Dielectric Withstand l Isolation Barrier Leakage Current 100% Tested At 240VAC: 3μA Max The PWR72 is a 3W, single-channel, dual-output DC/DC converter designed for low cost spot power conversion and ground elimination applications. l Low Isolation Barrier Capacitance: 10pF l Single-Channel; Dual Output l Six-Sided Shielding It provides a plus and minus output voltage approximately equal to the input voltage magnitude. The PWR72 operates over a wide range of input voltages from 5VDC to 22VDC. Its unregulated outputs give the PWR72 high efficiency power conversion. Surface-mounted devices and manufacturing processes are used in the PWR72 to give the user a device which is more environmentally rugged than most DC/DC converters. The use of surface-mounted technologies also gives the PWR72 superior isolation voltage. A third advantage of using surface-mounted technologies is low manufacturing cost. MECHANICAL NOTES: All dimensions are in inches (millimeters). GRID: 0.100 inches (2.54 millimeters) Marked with: specific model ordered, date code, job code. MATERIAL: Units are encapsulated in a low thermal resistance molding compound which has excellent chemical resistance, wide operating temperature range, and good electrical properties under high humidity environments. Lead material is brass with a solder plated surface to allow ease of solderability.
