7800 and 7900 Series Voltage Regulators

The LM78XX series of three-terminal positive regulators is available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut-down, and safe operating area protection. 78xx 79xx voltage regulators

7805 is popular for Embedded Systems and 7905 is sometimes used for the Dual Supply needs in such Microcontroller cards with Mixed Design sub-sections like A/D or Opamps.

Process Control Education

A Resource of Value for Industrial Engineering. Here is an Online Textbook for learning advanced process control concepts. The Reference includes Sample Process Control Course, Instrumentation for Process Control, WEB-Based Educational Resources for Process Control and Process Operability.

The Process Control Education Web Site

The material above can also be found on the -Process Control, 2nd Edition, McGraw-Hill, 2000 - ISBN 0-07-039362-1 a textbook by T. Marlin.

EMI RFI Mains Power Filters

EMI RFI Noise Filters are required in two situations, to prevent EMI from an Electronic Equipment Like A Dimmer, Thyristor Drive, SMPS or Switcher affecting other Modules in a System or Neighboring Equipment.

The Second Situation is when a Sensitive Equipment Like a Medical Apparatus or Precision Measuring Instrument has to be Immune to any Noise from outside, as it can affect performance.

Sometimes it is Accuracy that can get affected, but some electrical jolts can damage or desensitize fine sensors or positioning systems.

e-Learning Resources – Physics at Exeter

Excellent Online Educational Pages at Exeter. Students and Teachers can get ideas on how to enhance and enrich the Science Education Process. A Sound understanding of Physics and Chemistry is needed for stepping into “Electricity and Magnetism”. We have to move young minds into Electronics even before High School, as a part of Science itself. - delabs

Electric double layer capacitor an eFlywheel

The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint. These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may carry a lot of punch.

Also known as Ultracap, Goldcap, Supercap - Electric double layer capacitor, In Farads, like batteries, Energy Reservoirs or eFlywheel.

Electrical Safety and Equipment Testing

This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime, direct sunlight, moisture, humidity, sea wind (brine), corrosive fumes and chemicals. They should not be even placed near machines like a big lathe, sub-sonic or low frequency vibrations. - delabs notes
