Types of Variacs

The Types of Variacs available on the power source market today are assorted and varied.  Different Types of Variacs are specifically designed to enable them to perform their specific tasks at optimum performance levels.  The most common, and easily recognizable, Types of variacs are the open frame and bench models. Open frame and bench models types are differentiated as follows:

• Open frame model – this type of variac is designed to function as an integral part of larger piece of power source equipment, and thereby, usually features configurations for panel mounting in equipment racks.  Open frame model variacs are easily identifiable because of many of the exposed components, such as the inductor and other electrical connections.  It is important to note that only the output voltage is variable.  Optimum operation is achieved with very specific frequencies and input voltage.  Other input voltages, that are not specified, will not allow operation.

• Bench model – this type of variac, quite literally, “sits on a bench.”  Other easily identifiable features of a bench model variac include a control knob on the top and it's winding is shielded with metal shielding.  Other components on a bench model include fuses, AC outlet(s), on/off switches, line cord(s), and on occasion, voltage and/or current meters.

Several different Types of Variacs may appear small in size but they are designed to handle big jobs.  The typical open frame model has 240v input with up to 280v output.  The typical open frame model has 125v input and 140v output @ 15 amps.  Larger variacs than those just described are also available.  No matter what your power source requirements, a custom variac can be tailored to meet your specific requirements.

  Other characteristics and options that define Types of Variacs include the following:

• The combination of a variac with a voltage regulator will produce a wide range, well regulated, AC source.

• The combination of a variac with a isolation transformer can protect and isolate sensitive equipment from electrical interference and noise while providing outstanding variable voltage capabilities.

• The variac and isolation transformer combination also provides personnel safety and versatility for equipment service and engineering environments.

• For remote voltage control, motor driven variacs are available.

• For 400 Hz operation, single phase and three phase models are available.

• Three phase models can be configured in two gang open delta and three gang wye assemblies.  The choice of configuration will depend upon whether you wish to control output voltage or control three phase wye voltages.  Our variac specialists can help you determine the configuration that is best for you.
