RECOM has launched board-mount 5W AC/DC Converter Series for harsh environments.
The RAC05-K/PD3/H from RECOM is a board-mounted 5W Class II AC/DC converter series, intended for ‘fixed installations’ where higher levels of transients according to over-voltage category III are experienced, along with increased environmental pollution levels.
Michael Schrutka, RECOM AC/DC Product Manager comments “Our new 5W AC/DC converters provide real value when compliance with overvoltage category III is required especially along with higher levels of protection against ambient air pollution in harsh environments. By eliminated or at least significantly reduced the need for external suppression components. The parts will find applications in smart grid, renewable energy, smart metering and IoT systems, as well as monitoring food and beverage processing appliances.”
The converters are available with 5V, 12V or 15V single outputs and include enhanced clearances to meet OVCIII up to 5000m altitude. Nominal input ratings are 100VAC to 277VAC but the parts will withstand 480Vac without damage continuously.
The series is rated for operation in ‘Pollution Degree 3’ environments, where pollution can become conductive if condensation occurs.
The RAC05-K/PD3-H series is fully protected against short circuits and over-voltage in case of internal abnormalities’ and meets EN 55032 Class B EMI emissions level (floating output), without external components. No-load consumption is less than 0.5W to meet eco-design directives.
The parts are offered in a 2” x 1” x 1” high package and operate to 70°C in free air and 85°C (12V part) with 40% derating. Certifications include IEC/EN 62368-1 and UL 61010-1.
