Encapsulated DC/DC converter 28SMV250

plug-inhigh-voltageunregulated

This series of unregulated high voltage DC-DC converters are produced in an ultra-miniature encapsulated package. 110 different models are available. These single and dual output isolated units will operate over the temperature range of -25º C to +70º C with no heat sink or electrical derating. For military applications an operating temperature range of -55º C to +85º C is available. An optional environmental screening package per MIL-STD-883 is also available.
