Features

Applications

ꢀUPS systems

ꢀHighly reliable Closed Loop Hall Effect device

ꢀOpen Loop CT voltage output format: 4V out at nominal input

ꢀCompact and light weight

ꢀIndustrial robots

ꢀNC tooling machines

ꢀElevator controllers

ꢀFast response time

ꢀProcess control devices

ꢀExcellent linearity of the output voltage over a wide input range

ꢀExcellent frequency response (> 125 kHz)

ꢀAC and DC servo systems

ꢀMotor speed controller

ꢀLow power consumption at quiescent state (10 mA nominal)

ꢀCapable of measuring both DC and AC, both pulsed and mixed

ꢀHigh isolation voltage between the measuring circuit and the

current-carrying conductor (AC2.5KV)
