Topstek Current Transducer TH3A .. TH50A
TH 3A~50A
Features
Highly reliable Hall Effect device
Compact and light weight
Fast response time
Excellent linearity of the output voltage over a wide input range
Excellent frequency response (> 50 kHz)
Low power consumption (12 mA nominal)
Capable of measuring both DC and AC, both pulsed and mixed
High isolation voltage between the measuring circuit and the
current-carrying conductor (AC2.5KV)
Extended operating temperature range
Flame-Retardant plastic case and silicone encapsulate, using
UL classified materials, ensures protection against
environmental contaminants and vibration over a wide
temperature and humidity range
