Current Sense Amplifiers
-
Analog Devices’ current sense amplifiers offer excellent performance for a wide array of automotive and power management applications. These devices accurately amplify small voltages in the presence of large common-mode voltage, and provide high bandwidth, as well as level shifting and bidirectional capability. Excellent dc and ac accuracy over a wide temperature range from –40°C to +125°C minimizes errors in your measurement loop while not sacrificing on cost and package size.

Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.

Current Generator
MIG12100
-
MIG12100 is a current generator with wave shape 8/20 ìs. The exact waveform delivered is a function of the surge generator and the impedance to which the surge is applied. The generator can deliver up to 100kA impulse current supported by 12kV impulse voltage, making it ideal for testing big varistors with high hold-on voltage. Mechanically the MIG12100 consists of two large racks and a separate control console with high voltage output terminals protected by a glass acrylic test cabinet.
