Singer / Gertsch RT5 AC Voltage Ratio Transformer 6-dials
Singer/ Gertsch RT-5 Ratio Transformer Serial# 2554 The Gertsch RatioTran series of voltage dividers is based on the use of toroidal auto transformers designed for maximum accuracy of voltage ratio. Magnetic flux in the toroidal core links all turns of the transformer and induces the same voltage in each turn. ACCURACY NOT AFFECTED BY AGE The turns ratio of the transformer will not change with age. Changes in winding resistance have only a negligible effect on voltage ratio. Damage to the transformer will usually result in complete failure rather than deterioration of accuracy. HIGH INPUT IMPEDANCE The magnetizing inductance of a RatioTran is very large and the power loss in the transformer is very small. Therefore if the output of the RatioTran is not loaded, the transformer itself presents a high impedance to the source. LOW OUTPUT IMPEDANCE ... moreIf driven from a constant voltage source the RatioTran presents an impedance of only a few ohms as seen at the output terminals. This characteristic is useful in calibrating volt meters since loading effects can oft en be neglected. It is also useful in bridging applications since electrostatic shields may be connected to this low impedance point to minimize electrostatic pickup and capacitive loading of an unknown divider. 5 decade switches plus a variable adjustment control Max RMS input voltage must not exceed.35F or 350V Typical Use: AC BRIDGING A RatioTran may be used in a bridge circuit for precise measurement of the voltage ratio of unknown dividers. To realize the ultimate accuracy available from the RatioTran it is usually necessary to balance the bridge within a very small error voltage. To accomplish this. A high gain amplifier is usually required on the null detector side of the bridge. An AC VTVM can usually be used. If noise or harmonics of the bridge frequency prevent accurate balancing of the bridge, these voltages can be reduced by tuning the null detector. A tuned circuit can be used at the input of a VTVM or other null amplifier. Several types of audi

The ratio accuracy is traceable to the National Institute of Standards and Technology. The M-1011A operates over a frequency range of 50 to 10,000 Hz, and the M-1012A from 30 to 1,000 Hz. Variable AC voltage dividers demonstrate extreme precision in die measurement and generation of voltage ratios. Seven decades of tapped transformer windings are selected using special low resistance switches providing 0.1 ppm resolution and 1.0 ppm terminal linearity. The key to these standards is extremely stable toroidal transformers, resulting in precision and outstanding long term stability over a wide range of environmental conditions. The seven in-line control knobs permit quick, easy setting of die required ratios. The dials rotate independently through 360 degrees of rotation to simplify the settings. The switch settings are easily read from the large-numera

Singer Gertsch RT-20R Ratio Tran Precision AC Transformer Voltage Divider
Singer Gertsch Precision AC Voltage Divider Model RT-20R FREE SHIPPING 30 DAY MONEY BACK GUARANTEE Gertsch Products RatioTrans are high precision AC Voltage Dividers. They have the following useful features. 1. EXTREME ACCURACY: The Gertsch RatioTran series of voltage dividers is based on the use of toroidal auto transformers designed for maximum accuracy of voltage ratio. Magnetic flux in the toroidal core links all turns of the transformer and induces the same voltage in each turn. 2. ACCURACY NOT AFFECTED BY AGE: The turns ratio of the transformer will not change with age. Changes in winding resistance have only a negligible effect on voltage ratio. Damage to the transformer will usually result in complete failure rather than deterioration of accuracy. 3. HIGH INPUT IMPEDANCE: The magnetizing inductance of a RatioTran is very large and ... morethe power loss in the transformer is very small. Therefore if the output of the RatioTran is not loaded, the transformer itself presents a high impedance to the source. 4. LOW OUTPUT IMPEDANCE: I f driven from a constant voltage source the RatioTran presents an impedance of only a few ohms as seen at the output terminals. This characteristic is useful in calibrating volt meters since loading effects can often be neglected. It is also useful in bridging applications since electrostatic shields may be connected to this low impedance point to minimize electrostatic pickup and capacitive loading of an unknown divider. 5. MECHANICAL RUGGEDNESS. All models of the Gertsch RatioTrans are designed to withstand years of continuous usage without maintenance. I am a retired Telecommunications Engineer and College Electronics Instructor with over 35 years experience. I have a small metrology lab where I repair and calibrate used test equipment. I pride myself in customer service. Please let me know how I can make your buying experience more enjoyable or if you encounter a problem with your transaction. I am proud to be able to say I am a"Top Rated Plus" EBAY seller and I'm eage
