Inside a Simple Solenoid Water Valve

(1) Inside a cheap ebay solenoid water valve  from YouTube

The video above demonstrates different component within a typical solenoid valve.

Any current carrying coil will produce a magnetic field (for example) to exert a mechanical force of attraction or repulsion on any magnetic object. The effect is the same as produced by permanent magnet but in this  case of a current carrying coil, the field could be made to turn ON or OFF as desired by switching the current through the coil ON or OFF. This magnetic effect find applications in magnetic relay and solenoid.

A solenoid is a device that produces mechanical motion when a current carrying conductor coil receives electric current. The movable portion of a solenoid is the armature. A relay is a solenoid set up to actuate switch contacts when its coil receives electric current. Pull-in current is the minimum amount of coil current needed to actuate a solenoid or relay from its “normal” (de-energized) position. Drop-out current is the maximum coil current below which an energized relay will return to its “normal” state.

Armature is the movable magnetic object, and you can move most armatures with either direct current (DC) or alternating current (AC) energizing the coil. The polarity of the magnetic field is irrelevant for the purpose of attracting an iron armature. you can use solenoids to electrically open door latches, open or shut valves, move robotic limbs, and even actuate electric switch mechanisms.

The Importance of Low Voltage Battery Disconnect

Especially in Power Management Systems and Low Power Designs where battery used as backup or remote sensing it is imperative to include a mechanism to cut off demands from the battery bank at a convenient States of Discharge to safeguard the battery against premature damage. Inadequate provision for this requirement is responsible for failure of most solar power system where batteries are not well charged and drain out through exhaustion preventing users from appreciating benefits inherent in alternative energy system.

A good photo voltaic backup power systems should maintain the battery for reasonable length of time. It is therefore essential to include a device to cut the loads off the battery and this property is found in Low Voltage Battery Disconnect or LVBD for short. This device will automatically maintain healthy state of discharge of the battery. The device helps save killing the battery when the battery is not charging.

Secret of creating electronic circuits (Circuit Design)

Creating an electronic circuit digital or analog come easily to those who are either trained or familiar with the area, for an amateur, electronic circuit design is definitely an elaborate and complex puzzle. If you have interest in circuit creation or design: you should have the following points in mind:

Be comfortable with the functionality of circuits along with significance of the several components utilized in them.

It is also fundamental to stay up to date not just about the various presently available for sale but additionally with an understanding of the brand new components on regular basis. These will allow you to produce a better electronic circuit that actually works in an effective manner besides consuming less energy.

It is also good to possess a good knowledge of the usage and qualities of numerous electronic components inside a circuit.
It is also good to know the fundamental functionality of each component because the same component for example resistors, capacitors, transistors, etc. and different reasons for using each of them in various circuits.

Acquire the details for designs. These details you can acquired by training, online, offline or both and perhaps in any fundamental textbook, from data sheet supplied by electronic component producer. It is also to come up with in-depth understanding concerning the fundamental techniques of hooking up the various components inside a circuit. You should know how exactly the constituents could be associated with one another.

You must also discover the various mathematical equations associated with electronic circuitry along with useful limitation of every circuit.
The easiest method to find out about creating good electronic circuit design is as simple as employed by an expert who deals with the creating and repair of electronic circuits. This should help you attain a top-notch experience concerning the functionality and handling of diverse electronic products. Furthermore and additionally, you will find the ability to find about the various steps involved with circuits design in a practical manner.

Having mastered the skills of creating simple circuit designs, you can test out more complicated circuits.
Other Hints: circuit design software; electrical circuit design; schematic drawing; electrical drawing; circuit simulation; circuit design tutorial.
