The RAC series are suited for countries where voltage fluctuations far outside normal tolerances are not uncommon, since the ultra-wide input voltage range guarantees a stable, isolated DC output even if the AC power supply varies widely or is temporarily out of range. The RAC series can also be used with any mains input frequency from 0Hz (DC) up to 440Hz (aircraft electrical systems).
In order to reduce end-user costs, the compact power supplies have a built-in EN55022 Class B input filter that does not require any external components. You only need one converter type for many different applications because the RAC series operate with a stable efficiency down to 10% load, offering economies of scale and logistical savings. The converters feature 3kVAC isolation (3.75kVAC for RAC04/277 & RAC10/277) between input and output and are CE, EN and UL certified. RECOM offers a 3-year warranty as standard on all of its products.
