Isolation Amplifier, Four Channel — MOE Lab Tender Details

Isolation Amplifier, Four Channel

Four highly linear, crosstalk and noiseimmune isolating amplifiers for potentialfree measurement recording in static converter, drive and frequency converter technology used in conjunction with an oscilloscope or computer interface.

Current measurements are possible using built-in shunts. A multiplexer enables the four input signals to be displayed on one (storage) oscilloscope. All of the channels can be switched individually, the
corresponding zero-line can be displayed on the screen. Position and amplitude can be set separately on the screen for each channel.

A space vector indicator with LED display and oscilloscope output permits representation, measurement and evaluation of three-phase systems, particularly in connection with frequency converters and electrical machines. A mathematical module makes it possible to perform addition, subtraction and multiplication of two input signals.

A connectable filter permits fundamental waves to be reconstructed out of PWM signals. Isolation amplifier channelA, B, C, E:
