Constant-voltage non-isolated DC-DC converters for industry-control applications introduced by Wall Industries

EXETER, N.H., 22 Feb. 2011. Wall Industries Inc. in Exeter, N.H., is introducing the CV series of constant-voltage non-isolated DC-DC converters for wireless networks, telecom/datacom, industry control systems, semiconductor equipment, distributed power architectures, and microprocessor power applications.The CV series power electronics devices can deliver as much as 3 amps of output current in a small open frame package. These converters have output power ranging from 1.8 to 45 Watts and operate over input voltage ranges of 2.5 to 5.5, 4.5 to 14, and 10 to 30 volts DC. This series also provides non-regulated single outputs of 5, 12, and 24 volts DC.Features of these power management devices include efficiency to 95 percent, remote ON/OFF, and adjustable output voltage. All models in the CV series are RoHS compliant and have UL60950-1, EN60950-1, and IEC60950-1 safety approvals.The CV series of non-isolated DC-DC power converters have no minimum load requirements and operate over an ambient temperature range of -40 to 85 degrees Celsius (with derating). This series has vertical and horizontal SIP mounting configurations available.

The 5- and 12-volt models measure 0.37 by 0.24 by 0.61 inches and weigh 0.6 ounces. The 24-volt models measure 0.41 by 0.24 by 0.65 inches and weigh 0.7 ounces.

These converters have a mean-time-between-failure rating of 6,250,000 hours using Bellcore TR-NWT-000332 and 1,638,000 hours using MIL-HDBK-217F. These converters are also protected against over current, over temperature, and short circuit conditions.
