Topstek Current Transducers TPH10A .. TPH75A-LTC
TPH 10A~75A-LTC
Features
Highly reliable Hall Effect device
Compact and light weight. Three sensors in one package
Fast response time
Excellent linearity of the output voltage over a wide input range
Excellent frequency response (> 50 kHz)
Low power consumption (+12/-32 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
