Power-line and data-line SPDs have different application and selection criteria. Power-line devices are evaluated using parameters such as Up, Uw, discharge current and impulse current, while data-line protection depends on the communication or instrumentation interface. Because this page duplicates Blog 32, JEF should consolidate or clearly differentiate the two pages.
IS/IEC 61643 for power SPDs and IS/IEC 61643-21 for data-line SPDs — verify current editions. This page should be reviewed for keyword cannibalization with Blog 32.
JEF Techno can support the relevant engineering requirement through its applicable product, audit or consulting services. See the internal-link recommendations in Block I.
