Cost-Effective 5W Board Mount AC/DC Converters with Permanent Short Circuit Protection Designed for Household Applications
RECOM has released two new 5W, board-mount AC/DC converters that have a choice of standard footprints and are designed to meet general-purpose requirements for ITE and office use along with household applications or light industrial automation processes, with less than 0.1W no-load power consumption. The new RAC05E-K series is compatible with existing 3W part footprints and the new RAC05E-KT series is in the ‘EI30’ transformer-pack style. With load and temperature variations from -25°C to +55°C, both of these variants offer an input range of 90-264VAC (130-370VDC) and outputs of 4, 5, 12, 15, and 24V. Moreover, for both the devices outputs are semi-regulated but stay within +/-5% over line.
The new RAC05E-KT series meets EN 55014 and EN 55032 ‘Class B’ EMC limits without external components while the RAC05E-K requires just a simple external filter. With reinforced/3kVAC isolation, these devices hold safety certifications including UL/IEC/EN 62368-1 for IT/multimedia and IEC/EN 60335-1 for household applications. Moreover, no-load power consumption is less than 100mW and light load efficiency is high, enabling significant standby power to be drawn without exceeding ErP limits.
In addition, full protection is provided against short circuits, output over-voltage, over-current, and over-temperature with auto-recovery. The reliability of the parts is high with the -K series achieving over 1.6M hours MTBF at 25°C and the -KT series achieving over 2.2M hours, backed up by the RECOM 3-year warranty.
