Topstek Current Transducer TMQ100A .. TMQ1000A
TMQ100A~1000A
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 (16 mA nominal)
