Topstek Current Transducer TGU3A .. TGU51.6A
TGU 3A~51.6A
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
Applications
♦UPS systems
♦Industrial robots
♦NC tooling machines
♦Elevator controllers
♦Process control devices
♦AC and DC servo systems
♦Motor speed controller
♦Electrical vehicle controllers
♦Inverter-controlled welding machines
♦General and special purpose inverters
♦Power supply for laser processing machines
♦Controller for traction equipment e.g. electric trains
♦Other automatic control systems
