880B
The Model 880B is an amplifier which provides a current gain of 10 for use in high current calibration applications. It can be used as a stand alone amplifier to boost current from 1 to 10 ampere sources to the 10 to 100 ampere level. High, two-volt compliance allows for voltage losses in switches and connections, as well as in the ultimate loads, even at the 100 ampere level, without sacrifice of amplification accuracy. It is also compatible with Rotek Models 800A and 811A Precision Power and Energy Calibrators for testing watt and energy meters to current settings of 100 amperes. The Model 880B has a transformer-coupled input so there is no direct connection between the amplifier input and output terminals.
