Topstek Current Transducers TP25A .. TP300A
TP 25A~300A
Features
iHighly reliable Hall Effect device
iCompact and light weight. Three sensors in one package
iFast response time
iExcellent linearity of the output voltage over a wide input range
iExcellent frequency response (> 50 kHz)
i Low power consumption (33 mA nominal)
