TQPV50A ~350A
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 (> 125 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 encapsulated, using
UL classified materials, ensures protection against environmental
contaminants and vibration over a wide temperature and
humidity range
