Topstek Current Transducer TQH10A .. TQH50A-SP1
TQH10A~50A-SP1
Features
iHighly reliable Closed Loop Hall Effect device
iCompact and light weight
iFast response time
iExcellent linearity of the output voltage over a wide input range
iExcellent frequency response (> 100 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
