4-W power supply modules for extreme temperatures

July 10, 2014 // By Graham Prophet
With a wide operating temperature range of -40°C to +80°C, Recom’s 4W mini power supplies are equipped to supply outdoor sensors or control units in residential as well as industrial applications.

The RAC04-C/230 series is suitable for worldwide use due to its wide input voltage range of 80-264 VAC. The modules have short-circuit protected outputs and are available as single 3.3V, 5V, 12V, 15V or 24V or dual 5/12V, ±5V or ±12V versions. In a 36.7 x 27.2 x 17.1mm (L x W x H), the modules meet the requirements of class B EN55022 without external components, which is critical for home electronics. These high performance converters also achieve efficiencies of up to 79%.

This new series is pin-compatible with its predecessors with a 30% reduction in cost. Standby-consumption is 5 times less than required from the EuP-directive since the converters consume no more than 100 mW under no-load conditions. The modules are certified to EN/UL 60950-1 and have a MTBF up to 500.000h.
