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.

APPLICATIONS

 POWER FOR DATA ACQUISITION, OP

AMPS, ETC.

 PROCESS CONTROL
 PORTABLE EQUIPMENT
 TEST EQUIPMENT

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.
