Encapsulated DC/DC converter 28FR15S

plug-inregulatedinsulated

This series of encapsulated converters come in 60 different models. The highly regulated output is isolated from the input. The units will operate over the temperature range of -25º C to +70º C. No heat sink is required. These units are excellent for applications where the input voltage varies ±10% and the output must be held to ±0.1% single/and ±0.2% dual. The output voltage is maintained to within 0.2% from no load to full load for single and 0.4% for dual. OPTIONS AVAILABLE Per Mil.
