Topstek Current Transducers TD4A..TD25A-LTC
Features
TD 4A~25A-LTC
♦ 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 (> 25 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
Applications
♦ UPS systems
♦ Industrial robots
♦ Elevator controllers
♦ NC tooling machines
♦ Motor speed controller
♦ Process control devices
♦ Leakage current detection
♦ AC and DC servo systems
♦ General and special purpose inverters
♦ Other automatic control systems
