standard models operate from a universal input of 90 to 264V ac, providing
tightly regulated outputs of 3.3, 5, 8, 9, 12, 14, 15, 24, +5/+3.3, +8/+5 or
+12/+5 V dc. Standard features include filtering to EN55022 Class B, input/output
isolation of 3,000V ac, and tight line/load regulation. All models are
protected for over load, over voltage, and short circuit faults.
The MTBF (per MIL HDBK 217F) of the MPM-04 series is greater than 350 khours.
The MPM-04 has a Class II input (IEC61140).
This means it can be used without an earth
ground connection. All models are approved to EN 60950. The series is certified
to CE and is
The MPM-04 series is packaged in a
miniature PCB mount package. Each model is specified for operation over the
wide operating temperature range of -40 to +70C (ambient).
The MPM-04 series is a
solution for a variety of applications requiring high performance, miniature
size 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-04
series is a good choice for remote or portable equipment where a reliable
ground is often not available.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
