Topstek Current Transducer TQDV25A .. TQDV200A

Closed Loop Current Transducers

TQDV25A ~150A

Features

Applications

ꢀHighly reliable Closed Loop Hall Effect device

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

ꢀCompact and light weight

ꢀUPS systems

ꢀIndustrial robots

ꢀNC tooling machines

ꢀFast response time

ꢀElevator controllers

ꢀExcellent linearity of the output voltage over a wide input range

ꢀExcellent frequency response (> 150 kHz)

ꢀProcess control devices

ꢀ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)

ꢀElectrical vehicle controllers

ꢀInverter-controlled welding machines

ꢀGeneral and special purpose inverters

ꢀPower supply for laser processing machines

ꢀController for traction equipment eg. electric trains

ꢀOther automatic control systems

ꢀExtended operating temperature range

ꢀFlame-Retardant plastic case and silicone encapsulant, using UL

classified materials, ensures protection against environmental

contaminants and vibration over a wide temperature and

humidity range
