#### Operating 50Hz transformer on 60Hz supply

##### Wednesday, December 24, 2014

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 ...

#### What is a static (solid state) frequency converter?

##### Wednesday, November 5, 2014

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 is converting fixed frequency & voltage AC power to DC to AC by inner electronic parts and components, the multifunctional inverter converts ...

#### How to convert 110v/120v 60Hz to 220v/230v/240v 50Hz

##### Tuesday, October 14, 2014

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 po ...

## 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 ...

#### How to choose a Frequency Converter

##### Thursday, October 9, 2014

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 con ...

#### Frequency Converter Detecting (Troubleshooting) Steps

##### Thursday, October 9, 2014

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:

Second step: Power on the frequency converter and switch on power, push the green start button, check the LED indicators will be lighting or ...
