ELECTRONICS: Available immediately from MicroPower Direct, the MPM-20PB series is a family of single output, 20W switching power supplies. These compact modules include a universal ac input, full safety approvals, robust filtering and miniature packaging.Five standard models operate from a universal input of 90 to 264V ac (120 to 370V dc); providing tightly regulated single outputs of 3.3, 5, 12, 15, or 24V dc. Standard features include filtering to EN 55022 class B, an input/output isolation of 3,000V ac, and tight line/load regulation. All models are protected for over voltage, over load and short circuit faults.
The MPM-20PB has an IEC Safety Class II input (IEC 61140). This means it can be used without an earth ground connection. The MTBF (per MIL HDBK 217F) of the MPM-20PB series is greater than 250 khours. All models are fully approved to EN 60950. The series is RoHS compliant.
All MPM-20PB series models are packaged in a miniature 2.06- x 1.07- x 0.93-inch case. The pin-out is industry standard. Each model is specified for operation over the wide operating temperature range of -40 to 70C (ambient).
The MPM-20PB series is an ideal solution for a variety of applications requiring high performance, high power density and low cost. Applications would include industrial automation systems, machine/process control equipment, and telecommunications/data processing systems. With its Class II input, the MPM-20PB series is a good choice for remote or portable equipment where a reliable ground is often not available.
