EXETER, N.H., 27 March 2012. Wall Industries Inc. in Exeter, N.H., is introducing the DCHBW200 series DC-DC power converters for harsh-environment applications in railway systems, military embedded systems, wireless networks, industry control systems, semiconductor equipment, distributed power architectures, as well as telecommunications and data communications.
The power electronics devices deliver as much as 240 Watts and is packaged in an industry-standard 2.40-by-2.28-by-0.50-inch half-brick. The DCHBW200 power brick series consists of 3.3-, 5-, 12-, 15-, 24-, 28-, and 48-volt DC single-output models that operate over 4:1 input voltage ranges of 9 to 36, 16.5 to 75, and 43 to 160 volts DC.
The power bricks have efficiency of as much as 91 percent, soft start, adjustable output voltage, remote sense, 2250VDC I/O isolation, and positive remote on/off control. All models in the DCHBW200 series are RoHS compliant and have UL60950-1, EN60950-1, IEC60950-1, and EN50155 safety approvals.
The DCHBW200 series of DC-DC power converters have no minimum load requirements, operate over a case temperature range of -40 to 115 degrees Celsius, and have a mean-time-between failures (MTBF) rating of 1.01 million hours using Bellcore TR-NWT-000332 and 74,160 hours using MIL-HDBK-217F.
These converters are also protected against short circuit, over voltage, over current, and over temperature conditions, and offer several different options, including negative logic remote on/off, terminal blocks, case pin, sync pin, pin lengths, heat sinks, thru-hole inserts, and DIN rail clip.
