This is a voltage converter or transformer that can be used as a step up transformer in 110/120 volt countries or as a step down transformer in 220/230/240 volt countries. This heavy duty voltage transformer can be used for continuous duty. It will convert voltages of 220-240 volts to 110-120 and will also convert voltages from 110-120 to 220-240 volts.

These flexible frequency inverters offer four modes of operation: V/Hz (either constant or variable), enhanced V/Hz (either constant or variable), vector speed control, and vector torque control. They also feature dynamic torque response, auto-tuning (motor calibration), and low-speed operation. To assist in preventive maintenance programs, inverters also offer the feature of elapsed run time and elapsed power-on time. The electronic programming module (EPM) lets you easily setup and program the inverter in one of three ways: using the intuitive integrated keypad, in Windows® with the included Techlink software, or with the portable remote EPM programmer. Plus, your parameter settings are automatically archived, saving you time and improving your efficiency. Select from two enclosure types depending on your application environment. Use the NEMA 1 (IP21) enclosure for indoor use; it provides a basic level of protection to personnel on the outside and foreign solid ingress to the equipment inside. Use the NEMA 4X (IP65) enclosure for either outdoor or indoor use; it provides a basic level of protection and also a degree of protection against ingress of water (rain, sleet, snow, splashing water, and hosedirected water). Note: For options such as an installed communication module (CANopen, DeviceNet, or RS-485/ModBus) or an input EMC filter, please call our Application Specialists.

Simplified Design of V/F Converters shows how to design and experiment with V/F converters, both voltage-to-frequency and frequency-to-voltage. The design approach here is the same one used in all of John Lenk's best-selling books on simplified and practical design. Throughout the book, design problems start with guidelines for selecting all components on a trial-value basis, assuming a specific design goal and set of conditions. Then, using the guideline values in experimental circuits, the desired results are produced by varying the experimental component values, if needed.
If you are a working engineer responsible for designing VFCs, or selecting IC converters, the variety of circuit configurations described here should simplify your task. Not only does the book describe converter-circuit designs, but it also covers the most popular forms of VFC ICs available. Throughout the book, you will find a wealth of information on VFC ICs and related components, including how to test and troubleshoot completed circuits.
For all skill levels.

Voltage Converters - Why Do We Need Voltage Converters?
Commonly the word Voltage Converter is the name which is given to the device which acts as a switch which is in one location to control the voltage of gadgets which are in another location through power outlets. In the whole world most of the electrical outlets which produce alternating current with single phase will supply the voltage at 100 to 125 volts or 210 to 230 volts. The use of the Voltage converters is that they convert the voltage from 110 volts to 220 volts and 220 volts to 110 volts. Both the operations also can be done by some voltage converters.
The voltage converters are usually always sold with the with the plug at the end. Physical compatibility is also provided with the plugs as well.
Many methods are available for converting the voltage. A transformer is used to decrease or increase the voltage for alternating current. The voltage converters which will be used for small electronic gadgets will normally have a transformer will drop the smaller voltages such as to 4.5 volts to 12 volts. It will create a full wave rectifier which converts the alternating currents to the DC (direct current). Flattening the wave will be done by few additional Components. Few Components will contain only a transformer in the power supply which is external. That power supply will be with additional power in the gadget or a rectifier.
The voltage converters, which are sold for the usage in cars, have the DC outlets of 12 volts. The voltage converters don't necessarily come with transformer. Many a times, instead of a transformer, Zener diode is used, in order to bring down the DC voltage with huge loss of power. For the conversion of the alternating current the conversion of a low DC voltage to high voltage is required. Transformer usage is done for the increase in voltage. For the conversion of DC from AC, a conditioning circuit and a rectifier is used.
Two types of voltage transformers are available, namely the step up and step down voltage transformers. The conversion of a step up transformer is from 110 volts to 230 volts. The conversion of a step down transformer is from 230 volts to 110 volts. Many transformers will convert either ways. Voltage converters and transformers.
Throughout the world, voltage differs from country to country. The voltage level is either 220 volts or 110 volts. Plug sizes, plug holes and plug shapes also differ from country to country. Few countries such as in Canada and USA have the voltage of 120 volt with the frequency 60 Hz, while the others have the frequency of 50 Hz and the voltage of 220/240 volt. By using an appropriate voltage converter, this difference in voltages can be solved.
