NEW Stancor GSD-500 Auto Step-Down Transformer Input 230VAC Output 115VAC 500VA

Description

WHY & WHERE AUTO TRANSFORMERS ARE USED
Stancor’s stock Auto Transformers are connected for either step-down or step-up applications involving line voltages of 115 or 230 Volts., 50/60 Hertz. When isolation between the primary and secondary circuits is not necessary, and a direct connection between them is permissible, the Auto Transformer offers the advantages of smaller size, less weight, and lower cost. This type of unit is generally used in applications involving American appliances used abroad where our standard 115 Volt equipment must operate from a 230 Volt source. It is also used for foreign appliances designed for 230 Volt operation, which are to be used on our 115 Volt circuits. Our catalog items are designed for continuous rated output on either 50 or 60 Hertz.
It is important to bear in mind that the Auto/Isolation Transformers change only the voltage levels and do not change the frequency from 50 to 60 Hertz or vice versa. In appliances using synchronous motors, such as clocks or phonograph record changers and players, the speed will be different when using them on a frequency which differs from the frequency they were originally designed. In these cases the manufacturer of the appliance should be consulted to obtain the proper motor.
The VA rating is equivalent to a Wattage rating where a resistive load and/or unity power factor exists. When inductive loads such as motors are used (as in a motor driven appliance) the power factor is not unity and to be accurate the output is expressed in VA, which is the product of the output voltage and the output current (Amps).
When selecting one of these items for use with an appliance which includes a motor, allowance should be made for the starting current of themotor which is somewhat higher than the running current. This information is generally available from the appliance manufacturer. Information pertaining to the AC Wattage or current required by an appliance is generally marked on the item by the manufacturer and should be observed. It is much better to buy a transformer with a larger VA rating than you will actually need because of larger motor starting currents and variations in the line voltage and/or frequency in some locations, which could cause overheating.
General Information
All of these items have Class “A” insulation and are rated to have a maximum operating temperature of 105 Degrees C. These units may be used with rectifiers but the form factor as explained elsewhere in this catalog should be observed for various combinations of rectifier circuits and types of load following the rectifier. These items are made with our standard N.E.M.A. plugs and receptacles, primarily for use in this country. However, if used overseas where different types of plugs are necessary, an adapter plug should be used or our plug removed and a foreign plug attached to the end of the line cord.
