Voltage and Current Amplifier
CMS 356
-
The CMS 356 is a voltage and current amplifier for analog low-level signals provided by a CMC test set or by any other signal source, such as a digital real-time power system network simulator. When used in combination with a CMC test set, the amplifier extends the capabilities of the test set to provide additional output channels and higher amplitudes.

Low Current Probe 80A
695
-
Great tool for accurate measurement of low current. Use with your graphing meter or lab scope to view current waveforms on fuel injectors, fuel pumps, primary ignition coils and more. Also works very well with digital multimeters. Resolution of 10 milliamps is low enough for most parasitic drain testing. In addition, the clamp opening of 1/2 inch is large enough to clamp over most negative battery cables for those parasitic drain tests.

Multiplying Current Output D/A Converters
-
Analog Devices offers a wide range of high precision, multiplying current output (IOUT) D/A converters (DACs) that feature ±1 LSB INL and DNL specifications, from 12-bit up to an industry-leading 18-bit resolution. Our portfolio includes single and multiple D/A converters in small packages with parallel or serial SPI interfaces. Multiplying current output R-2R D/A converters allow for an external amplifier that’s optimized for specific applications and that does not require reference buffering, which enables high linearity. The SoftSpan™ feature allows software selectable output spans, therefore eliminating the need to add precision gain stages and the associated external jumpers, precision resistors, and amplifier circuitry. Integrated precision resistors allow for reference inversion, bipolar offset, and offset and gain adjustment.

IEC Standard Burden Sets (Current)
IEC Burden Sets
-
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.
