If fed to a relay coil will both chatter the relay in a same way ? Please tell more about the term 'harmonics'.
And got the following answer:
DC.. Means Direct Current.. there is nothing called full wave DC or half wave DC.. because DC doesn't have a frequency component. if you convert DC to AC.. then AC component will contain frequency.. that again depends upon type of converter used.. DC to AC converter is called a Inverter.. Harmonics.. Harmonics are currents or voltages with frequencies that are integer multiples of the fundamental power frequency being 50 or 60Hz (50Hz for European power and 60Hz for American power). For example, if the fundamental power frequency is 60 Hz, then the 2nd harmonic is 120 Hz, the 3rd is 180 Hz, etc. In modern test equipment today harmonics can be measured up to the 63rd harmonic. When harmonic frequencies are prevalent, electrical power panels and transformers become mechanically resonant to the magnetic fields generated by higher frequency harmonics. When this happens, the power panel or transformer vibrates and emits a buzzing sound for the different harmonic frequencies. Harmonic frequencies from the 3rd to the 25th are the most common range of frequencies measured in electrical distribution systems. Additionally, harmonics are caused by and are the by-product of modern electronic equipment such as personal or notebook computers, laser printers, fax machines, telephone systems, stereos, radios, TVs, adjustable speed drives and variable frequency drives, battery chargers, UPS, and any other equipment powered by switched-mode power supply (SMPS) equipment. The above-mentioned electronic SMPS equipment is also referred to as non-linear loads. This type of non-linear loads or SMPS equipment generates the very harmonics they’re sensitive to and that originate right within your building or facility. SMPS equipment typically forms a large portion of the electrical non-linear load in most electrical distribution systems. There are basically two types of non-linear loads: single-phase and three-phase. Single-phase non-linear loads are prevalent in modern office buildings while three-phase non-linear loads are widespread in factories and industrial plants.

The ac relay coil function incredibly properly with distinctive applications which are specific to power distribution and protection. The relays come with wide adjustment ranges having a scale that is certainly easy to read either in three or 4 digits in accordance with the model. These ac relay coil support in increasing the flexibility with the applications, lessen the overall energy and upkeep charges. There are relays which are employed for common purposes which come in reliable designs with rapid replacement selections. And there are models that happen to be utilised for industrial applications and heavier duty applications that function on massive loads. These solutions are created to meet the lifetime industrial handle needs in the applications.
Their most recent items are the Time counter, Timer Delay, ac relay coil, Rapid Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different others. The internet site gives a detailed description of every single model in numerous categories of ac relay coil couplings and sensors. These products are particularly beneficial for high-risk applications. The ac relay coil are also obtainable with capabilities like various timing ranges and functions. The corporation is presently searching for agents and dealers who can promote and sell their factory created items. They are usually on a lookout for developing new and more reputable products depending on the desires and requirements from the industry.
