140W ac-dc PSU handles 210W surges for 10s

The RACM140E-K series offers a choice of 12, 15, 24, 36 (136.8W rated) or 48Vdc depending on model.

The input range is 80-264Vac and they measure 147 x 81.5mm – either 38mm tall for the open frame versions or 40mm enclosed (15 and 36V enclosed versions are special-order). Fixings are for the traditional ‘3 x 5inch’ footprints.

Standard input and output connectors are pin headers to accept Molex 41695 housings with 2478 crimps, but enclosed versions also have a special-order push-fit connection option.

Safety certifications include IEC/EN60335-1, IEC/EN62368-1 and, for medical applications, IEC/EN ANSI/AAMI 60601-1 with 2MOPP (means of patient protection), low touch current (<100µA, <500µA with single fault) and low leakage current (<300μA) for BF (body-floating) use.

“Class B EMC performance is met for conducted emissions with a wide margin,” said the company.

Other ratings are: for use in pollution degree 2 environments, over-voltage category III up to 2,000m altitude, and OVC II up to 5,000m.

Nominal operating range is -40 to +90°C with natural convection, with derating above temperatures between 35 and 65°C depending on variant and input-voltage.

No load consumption is typically 100mW and efficeincy peaks between 86 and 90% – rising with increasing output voltage.

Calculated lifetime is 440,000hr MTBF at 25°C (MIL-HDBK-217, GB condition), and there is a three year warranty.

The company sees them being used in home and building automation, telecom and datacom, industrial, medical, e-mobility, infrastructure, test and measurement.
