GoHz Frequency Converter is a specialized AC power source to simulate worldwide electric power to make your appliances work in its perfect circumstance. By installing GoHz frequency converter, you can bring American 60Hz machines (for both single phase and three phase machines) to be operated well in European 50Hz electric power, vice versa, or even get 400Hz output for aircrafts.

This article will show you the basic wiring/co ...

USA/Canada single phase 240v power source consists of 4 lines, named L1, L2, N, G
L1-N = 120V, L2-N = 120V, L1-L2 = 240V
Even though GoHz single phase frequency converter can be made for 120v input, it will require additional auto-transformer inside the frequency converter to boost the voltage from 120v to 240v which will increase the weight of the converter along with the total costs.

Generally, GoH ...

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;

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. 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 i ...

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 ...

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?

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 earlie ...

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 ...
