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)
♦ Low power consumption (<12 mA)
♦ 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
