TES 3-4812 TRACO Power

DC/DC Converters TES 3 Series, 3 Watt CB Scheme UL 60950-1 Features SMD package Wide 2:1 input voltage range I/O isolation 1500VDC Under voltage lockout Operating temp. range 40C to +85C Short circuit protection High accuracy of pin co-planarity Lead free design RoHS compliant 3-years product warranty The TES-3 series is a family of high performance 3W dc-dc converter modules featuring wide 2:1 input voltage ranges. The 15 models come in a low prole fi SMD package with dimensions of 32.3 x 14.8 x 10.2 mm. A high efcfi iency allows an operating temperature range of 40C to +85C at full load. This product is qualiefi d for soldering in a high temperature lead-free reflow solder process. Typical applications for the converters are battery operated equipment, instrumentation, communication and industrial electronics, everywhere where an isolated, tightly regulated voltage is required.
