Frequency Changer

High quality power supplies are essential in the R&D and production lines of electrical and electronic manufacturing companies. Frequency converter is a device to transform a certain frequency (e.g. 50Hz, 60Hz) & voltage AC power into another voltage and frequency power supply, to simulate any power system standards in the world. It's a common device being used for various industries, laboratories and export-oriented electronic manufacturing companies. Calibration is essential for fre ...

While switch to "self-control", all of the output parameters are controlled by the frequency converter, at the moment, all external controls are inoperative;
Frequency converter PLC control switching
While switch to "external PLC control", the keyboard of the frequency converter is inoperative, all control commands are transmitted by external PLC, refer to following instru ...

Why voltage in some countries is 220V (208V, 230V, 240V) and 110V (100V, 120V) in some countries? Why can't we have the same Voltage and what are the Pros & Cons of using 110 V or 220 V in their Respective regions?

110V or 220V, Each system has its own advantages and disadvantages, so each country before designing a system Engineers sat down agreed on factors and concluded on which system to use taking in account:
Their ...

Aircraft electrical components operate on many different voltages both AC and DC. However, most of the aircraft systems use 115 volts AC at 400 hertz or 28 volts DC. 26 volts AC is also used in some aircraft for lighting purposes, where the power is generated by a commutator which regulates the output voltage of 28 volts DC.Aircraft AC power, normally at a phase voltage of 115V, is generated by an alternator, g ...

Case: I am restoring a 1960s analog audio tape recorder for high quality audio use, the tape recorder is a USA model operating on 120VAC at 60Hz, the mains voltage in Singapore where the machine will be operated is 230VAC but 50Hz. Other converters that convert 230VAC/50Hz to 120VAC/60Hz have been unsuitable -- I hear high distortion and square wave noise to break through in to the audio in ...

All variable frequency drives using power electronics are essentially "frequency choppers". Either the VFD is a current-sourced inverter topology, or a voltage-sourced inverter topology. To obtain the desired output (usually defined as voltage at some specific frequency), the incoming signal gets "chopped" and rectified to produce a DC pulse, which is then inverted back produce a "sample" of a fraction of a sinusoidal waveform.

The sample can v ...

I require urgently 75 hp motor which should be compactible for both 50Hz/60Hz, I'm very much confused as frequency changes speed will change but I'm wondering how the power rating of the motor remain same in practical power must vary but manufacturer claims power remains constant? Is it possible? 75hp motor

A: It is possible for a motor to deliver the same power output at 50Hz ...

Electrical machines designed for 50Hz can usually work safely in 60Hz power supply, but not applicable to 60Hz machines to be run in 50Hz power supply. This is because impedance of 50Hz machines increases if operate in 60Hz supply which also lowers the running ampere, while if 60Hz machine run in 50Hz power system will experience increase in running ampere & overheating that will result to reduced life expectancy of the equipment. In motors coupled to water pumps or compressors increase o ...

Why not a 59 Hz? I prefer a prime number. If I were J.P. Morgan, I'd like to make Tesla have such a cool frequency. Or US yields to 55 Hz, and Germany get a 5 Hz bonus.
In the true world, a wide range of frequency for electrical machine could work economically, but in a real world, people make the standard, and 60 Hz simplified, e.g. the calculation. I guess Nikola Tesla had more common sense than I have. However, if I were born 100 years earlier ...

Following texts are the video transcription of GoHz frequency converter parameter setting.

First, we see the frequency converter panel of parameter settings, there are total 10 parameter sets, count from M0 to M9, each parameter set store the values of voltage, frequency and running time. Press the UP/DOWN buttons to select which parameter s ...

GoHz frequency converter is a great solution for converting 50Hz to 60Hz among different countries, also can convert 60Hz to 50Hz, in additional of frequency adjusting, the output voltage is changeable from 0-300 volts for single phase power supply, 0-520 volts for three phase power supply. This article shows the basic operation guidelines of GoHz static frequency converter, you can easy set up a converter by following this guide. ...

You can run the 50Hz transformer on a 60Hz supply. Now since the frequency has changed the only variable thing in the existing transformer that can change (assuming simple one input and one output) is the flux density. In its simple form we are operating the transformer (60Hz/50Hz = 1.2) at 20% lower flux density.

If the things were reversed the flux density would be 20% higher and may saturate depending on design. You can even run the transformer at 400Hz providing that the volta ...

Static (solid state) means no moving parts inside the frequency converter, the definition is relative to rotary frequency converter which using an induction motor to achieve variable frequency.
Static frequency converter
Static frequency converter is converting fixed frequency & voltage AC power to DC to AC by inner electronic parts and components, the multifunctional inverter converts ...

Home appliances, like TV, speaker, lights, may work with both 50 Hertz and 60 Hertz, but some appliances especially with electric motor inside it, like air conditioner, fridge, can only work with 50Hz or 60Hz. If a 50 Hz motor working on 60 Hz power system, the motor speed will be 20% faster, then cause over temperature and shorten its service life.

We all know, most European and Asia countries powe ...

What is 50Hz, 60Hz?

Alternating current (AC) is changing the direction of the current periodically; Cycle is the time of a cyclical change of the current; Frequency is the times of the current changes per second, unit Hertz (Hz). AC current direction changes 50 or 60 cycles per second, in accordance with 100 or 120 changes per second, then the frequency is 50 Hertz or 60 Hertz.

50 Hz and 60 Hz power sources are most often used in i ...

Frequency converter can help you change 60Hz to 50Hz, also can boost 110V to 220V by inner step up transformer, vice versa. Before you buying a frequency converter, it's better to understand what kinds of loads the frequency converter will be connected with. There are five common load forms: 1, resistive load; 2, inductive load; 3, capacitive load: 4, rectifier load; 5, regenerative load; 6, mixed loads. We should select the frequency conv ...

First step: For safety, please cut off the frequency converter power before doing it.
Open the left and right side covers of the converter, as show in following figures:
