Closed Loop Current Transducers

TQDV25A ~150A

Features

iHighly reliable Closed Loop Hall Effect device

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

iCompact and light weight

iFast response time

iExcellent linearity of the output voltage over a wide input range

iExcellent frequency response (> 150 kHz)

iLow power consumption at quiescent state (10 mA nominal)

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

iHigh isolation voltage between the measuring circuit and the

current-carrying conductor (AC2.5KV)

iExtended operating temperature range

iFlame-Retardant plastic case and silicone encapsulant, using UL

classified materials, ensures protection against environmental

contaminants and vibration over a wide temperature and

humidity range
