DC/DC Converters TEN 3WI Series, 3 Watt RoHS compliant Features ◆ Ultra-wide 4:1 Input Range ◆ Full SMD-Design ◆ High Efficiency up to 84% ◆ Extended Operating Temperature UL 60950-1 Range -40°C to +85°C ◆ Excellent Load and Line Regulation ◆ Indefinite Short-circuit Protection ◆ I/O-Isolation 1’500 VDC ◆ Input Filter meets EN 55022, Class A and FCC, Level A without external Components ◆ Shielded Metal Case with insulated Baseplate ◆ Lead free Design, fully RoHS compliant ◆ 3 Year Product Warranty The TEN 3WI series is a family of dc-dc converter modules with 3W output power, featuring ultra wide 4:1 input voltage ranges of 9-36VDC or 18-75VDC. They come in a DIP-24 plastic package with industry-standard footprint. A high efficiency up to 84% allows operation ambient temperatures of –40°C to +70°C at full load. A built-in EMI input filter complies with EN 55022,class A without need of external components. Further standard features include over voltage protection and continuous short circuit protection. Typical applications for these converters are battery operated equipment and distributed power architectures in communication, instrumentation and industrial electronics, everywhere where isolated, tightly regulated voltages are required Models Ordercode Input voltage range Output voltage Output current max.
