Hertz is the measurement of light frequency in cycles per second. Lumen is the measurement of luminous flux or amount of light produced by any source. Volt is the measurement unit of electric potential difference between two points in contrast to amp that is the measurement unit of electric current passes through a circuit in one second.

Lumens Luminous flux is measured in lumen that is the derived unit. Hertz The frequency of light is measured in the units called Hertz. Watts Measurement of rate of energy produced in the form of electrical power is made in watts that are the smallest and derived units of power.
The opposite is also true - you can sometimes gain kW when you convert from 50 Hz to 60 Hz because you speed the engine RPM up. The number of wires and plugs used varies greatly by region since each country is evolving their electrical grids at a different rate and over time so these are only provided as a good starting point and general guide.
Single-Phase Voltage Volts. Three-Phase Voltage Volts. Frequency Hertz. Plug Type. Abu Dhabi. American Samoa. Antigua and Barbuda. Voltage describes this potential. The greater the voltage, the more potential the electricity source has to do work. The potential to do work should not be confused with actually doing work.
For instance, a battery that is sitting on a table but not connected to anything has a voltage, or the potential to do work such as lighting a light bulb. However, the battery will not light the bulb unless it is connected to the bulb in an electric circuit. Only then will the battery actually do work. The unit of voltage is the volt.
One volt is defined as doing one joule 0. Electric current is simply the flow of electrons or, in some cases, positive charges.
In a circuit, current delivers energy from a source of electricity to an electrical device e. The unit of current is the ampere, or amp. An ampere is defined as having one coulomb 6. The relationship between voltage and electric current is similar to the relationship between the height of a waterfall and the water that flows down it. A height is needed for the water to flow down the waterfall. The greater the height of the waterfall, the more energy the water has when it reaches the bottom.
If no height exists, the water will not flow and it will not have any energy due to motion. A voltage similar to height is needed to cause an electric current to flow think of cascading water so that it can deliver energy to an electrical device or appliance. There are other considerations associated with an increase in speed besides the increase in load. These include mechanical limitation, vibration limits, heat dissipation, and losses.
The best solution is to operate the motor at the speed for which it was designed. If that is 50 Hz. These drives will convert the 60 Hz line power to 50 Hz at the motor terminals.
There are numerous other benefits that will be realized with this solution. These benefits include:. Source: Precision Electric, Inc. Email: sales ksbusa.
Sub-Navigation Conquer The Clog. 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 or changes per second, then the frequency is 50 Hertz or 60 Hertz.
These benefits include: improved efficiency power regulation often better than the utility will supply motor over current protection better speed control programmable output to perform other tasks improved performance.
