Executive Summary

• Among those specifying, recommending, and/or buying dc power supplies, 78% do so for inplant requirements and 43% buy for OEM needs.

• The most common application for dc power supplies is continuous and batch processing (31% of respondents).

• Reliability was by far the most important feature sought when selecting dc power supplies. Product quality is the most important feature when selecting a manufacturer of dc power supplies.

• Analog outputs and relay (contact) output were of about equal importance when evaluating the importance of communication methods.

• 51% of respondents are currently using and will continue to use Ethernet TCP-IP for their communication network on dc power supplies. RS-232 and RS-485 are used by 54% and 43% respectively.

• 59% of respondents are currently using and will continue to use DIN-rail mounted linear regulated dc power supplies. DIN-rail mounted high isolation is currently used / will continue to be used by 49% of respondents.

• SolaHD tops the list of dc power supply equipment manufacturers purchased from in the past 12 months. Rockwell Automation (Allen-Bradley) was next most at 36%. Of the 19% “other” mentions, none amounted to more than 1% of the total mentions.

• 77% of respondents have purchased 20 or fewer dc power supplies in the last 12 months. 16% purchased more than 50 units.

• Two-thirds of respondents spent $10,000 or less in the past year on dc power supplies. 16% spent more than $25,000.

• 24% of respondents expect their purchase of dc power supplies to increase in the next year. 67% expect their purchase level to remain the same. • Sixty-five percent of Control Engineering subscribers responding do not receive Control Design magazine. Seventy-five percent do not receive InTech.
