Input filtering regulation. minimizes reflected ripple current. Output ripple volt- age and switching transients are reduced by filtering The PWR70 provides a plus and minus output volt- the PWR70 outputs. age approximately equal to the input voltage mag- nitude. It operates over an input voltage range of The PWR70 is tested in compliance with UL544, 10VDC to 18VDC. Isolation voltage is a minimum VDE750, and CSA C22.2 dielectric withstand voltage of 2000VDC. requirements. MECHANICAl NOTES: All dimensions are in inches (millimeters). GRID: 0.100 inches (2.54 millimeters) WEIGHT: 15gm (0.53oz) 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 en- vironments. l ead material is brass with a solder plated surface to allow ease of solderability.ElECTRICAl SPECIFICATIONS At T = +25C, +V = 15VDC, and I = 15mA unless otherwise noted.
