Topstek Current Transducer TQDV25A .. TQDV200A
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)
i Low power consumption at quiescent state (10 mA nominal)
i Capable 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
