Details Regarding Contactor-Its Construction, Types and Applications

A contactor is the major part in an electrical circuit. It can stand on its own power control device or a part of a starter. Electric contactors are mainly utilized to connect and break power supply lines that runs through power lines or it repeatedly establish and interrupt electrical power circuits. You will find its use in light loads, complex machine control. Between the control circuit and power circuit it is frequently considered as an intersection point as it is controlled by the control circuit. It even controls the circuit between powers and loads.

Contactors are switching devices that are electrically controlled and are used for switching electrically. The basic operation of this is quite similar to a relay. Short circuit or overload protection cannot be provided by them but they can break the contact when coil excites.

Construction of a Contactor

The electric contactor mainly constitute of two iron cores, where one is fixed and the other one is the movable coil and is an insulated copper coil. Here on the fixed core the copper coil is present. For power connection there are six main contacts. In this three are fixed cores and the other three are movable cores. From pure copper these contacts are made, and to withstand high starting current and temperature the contact points are made from special alloy. Auxiliary contacts a spring which is located between coil and the movable core.

The three main parts are-

Enclosure

It acts like an insulator and protector, which from any electrical contact, dust; oil, etc protects the circuit. It is made from various materials like Bakelite, Thermo setting plastic, Nylon 6, etc.

Coil

It provides a force which is needed to close the contact. The coil is even referred as an electromagnet. To safeguard the coil and contactor an enclosure is used.

Contacts

The major function of Fuji magnetic contactor is that it passes the current to different parts of the circuit. They are then classified into power contacts, contact springs and auxiliary contacts. Here each of the contacts has its own functions, which in principle of operation of the contactor is properly explained. Follow us on Twitter

Know about Modified VS Pure Sine Wave Inverter

Changing direct current (DC) to alternating current (AC), an inverter is an electrical power converter. With the use of appropriate control, switching, and transformers circuits, the converted AC can be at any required frequency and voltage.

To supply AC power from DC sources such as batteries or solar panels, Inverters are commonly used. Modified Sine Wave Inverters or Pure Full Sine Wave Inverter is 2 major types of power inverters generally.

Modified Sine Wave

A pure sine waveform is Modified Sine Wave inverters approximately. While being less expensive than pure sine waveform inverters, most devices are designed to satisfy the efficiency requirements.

Pure Sine Wave Inverters Benefits over Modified Sine Wave Inverters

• With very clean power like utility-supplied electricity and low harmonic distortion, Output voltage wave form is pure sine wave.
• Inductive loads like motors and microwave ovens run cooler, quieter and faster.
• In answering machines, fluorescent lights, fans, TV, audio amplifiers, Fax, and Game consoles, electrical noise and Reduces audible.
• Prevents noise in monitors, weird print out, and crashes in computers and glitches.

You can buy PSW Inverter online. Not working with modified sine wave inverters, these are the following devices:

• Medical equipment like oxygen concentrators
• X-10 automation system for home
• Certain computers and laptop
• Magneto-optical hard drives, photocopiers, Laser printers
• Power tools employing variable speed control or solid state power
• Some fluorescent lights have electronic ballasts
• Some pellet stoves and new furnaces with microprocessor control
• For cordless tools, some battery chargers
• With microprocessor and speed control, Sewing machines
• Digital clocks having radios

The Benefits of Pure Sine Wave Inverter

• With sine waves, all equipment currently is designed for use on the market.
• If they do not use sine wave power, some appliances, particularly variable speed motors and microwaves, will not produce full output.
• At all unless you use a pure sine wave inverter, particularly medical equipment may not function in other devices.
• A much higher equivalent wattage is produced by a 1000watt Pure Sine Wave Inverter produces as compared to a modified sine wave one. The greater the variety of electrical appliances and devices, you will be powering It is somehow believed that the more you will be using this type of inverter. Follow us on Facebook
