289J

The 289J is a precision wide bandwidth Synchronized Isolation Amplifier provide a small signal frequency response from DC to 20kHz (-3dB) and a large signal response from DC to 5kHz (full power) at a gain of 1V/V. New design offers true 3-port isolation, ±2500V DC between inputs and outputs (or power inputs), as well as 240V rms between power supply inputs and signal outputs. Using carrier modulation techniques with transformer isolation, model 289 interrupts ground loops and leakage paths and minimizes the effect of high voltage transients. It provides 120dB common mode rejection between input and output common. The high CMV and CMR ratings of the model 289 facilitate accurate measurements in the presence of noisy electrical equipment such as motors and relays.
