| PWR70 SERIES 3 WATTS UNREGULATED DC/DC CONVERTERS LOW COST, HIGH ISOLATION FEATURES TESTED IN COMPLIANCE WITH UL544 OUTPUT POWER TO 3W HIGH ISOLATION VOLTAGE: 2000VDC SIX-SIDED SHIELDING INPUT AND OUTPUT FILTERING LOW PROFILE PACKAGE: 0.4" High APPLICATIONS POWER FOR DATA ACQUISITION, OP AMPS, ETC. PROCESS CONTROL PORTABLE EQUIPMENT TEST EQUIPMENT DESCRIPTION The PWR70 is a dual-output DC/DC converter designed for general purpose power conversion applications where high efficiency is more important than load regulation. The PWR70 provides a plus and minus output voltage approximately equal to the input voltage magnitude. It operates over an input voltage range of 10VDC to 18VDC. Isolation voltage is a minimum of 2000VDC. Six-sided shielding suppresses electromagnetic radiation which could disturb sensitive analog measurements or interfere with system timing signals. Input filtering minimizes reflected ripple current. Output ripple voltage and switching transients are reduced by filtering the PWR70 outputs. The PWR70 is tested in compliance with UL544, VDE750, and CSA C22.2 dielectric withstand voltage 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 environments. Lead material is brass with a solder plated surface to allow ease of solderability.
