image003-micropowerAvailable 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 264 VAC (120 to 370 VDC); providing tightly regulated single outputs of 3.3, 5, 12, 15, or 24 VDC. Standard features include  filtering to EN 55022 class B, an input/output isolation of 3,000 VAC, 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°C to +70°C (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.

MicroPower Direct products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all modules as a routine part of our production process.
