ELECTRONICS: MicroPower Direct’s MPM-03S series is a family of single output, 3W switching power supplies. These low-cost modules include a universal ac input, full safety approvals, robust filtering and miniature DIP packaging. Six standard models operate from a universal input of 85 to 264V ac; providing tightly regulated single outputs of 3.3, 5, 9, 12, 15 or 24V dc. Standard features include universal 85 to 264V ac inputs, filtering to EN55022, input/output isolation of 3,000V ac and very low leakage current. All models are protected for over temperature and short-circuit faults. The MPM-03S has a Class II input (IEC61140). This means it can be used without an earth ground connection. The series, which is RoHS compliant, is packaged in an ultra-miniature DIP package. Each model is specified for operation over the wide operating temperature range of -25 to 71C (ambient).
