Topstek Current Transducers TE50A .. TE500A-S12
TE 50A~500A-S12
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
