Topstek THT37.5A
Topstek Current Transducer THT6A .. THT37.5A
THT 6A~37.5A
Features
Highly reliable Hall Effect device
Wide selectable input ranges with flexible pin configurations.
Compact and light weight
Fast response time
Excellent linearity of the output voltage over a wide input range
Excellent frequency response (> 50 kHz)
