The benefits of high volume production and semi-automatic assembly allow for a lower selling price without sacrificing our high quality standards. They are UL certified for safety, offer reasonable efficiency and operating temperature range of -40 to +85C. Single Output Selection Guide Part nom. Input Output Output Efficiency max.
