Osborne Transformer Corp.
Osborne Saturable Reactors are designed to provide a variable output voltage through the use of variable impedance connected in series with a constant impedance load. Each saturable reactor’s impedance is determined by the application of DC power to a control winding. As the level of power supplied to the control winding is increased, the saturable reactor becomes more saturated. This reduces the impedance of the AC gate winding, and increase the amount of the supply voltage that is transferred to the load. Conversely, as the power is reduced to the control winding, the reactor becomes less saturated, the gate winding has more impedance and less of the input voltage is provided to the output impedance. This approach provides excellent quality, reliability, and control when designed to match the requirements of a specific application.

Analog Devices Inc.
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.
