Topstek Current Transducer TQH5A .. TQH50A

TQH5A~50A

Features

Applications

ꢀHighly reliable Closed Loop Hall Effect device

ꢀUPS systems

ꢀCompact and light weight

ꢀIndustrial robots

ꢀFast response time

ꢀNC tooling machines

ꢀExcellent linearity of the output voltage over a wide input range

ꢀExcellent frequency response (> 100 kHz)

ꢀ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)

ꢀElevator controllers

ꢀProcess control devices

ꢀAC and DC servo systems

ꢀMotor speed controller

ꢀElectrical vehicle controllers

ꢀInverter-controlled welding machines
