Topstek Current Transducer TH3A .. TH50A TH 3A~50A
www.DataSheet4U.com Features
Applications
i UPS systems i Industrial robots i NC tooling machines i Elevator controllers i Process control devices i AC and DC servo systems i Motor speed controller i Electrical vehicle controllers i Inverter-controlled welding machines i General and special purpose inverters i Power supply for laser processing machines i Controller for traction equipment e.g. electric trains i Other automatic control systems
i Highly reliable Hall Effect device i Compact and light weight i Fast response time i Excellent linearity of the output voltage over a wide input range i Excellent frequency response (> 50 kHz) i Low power consumption (12 mA nominal) i Capable of measuring both DC and AC, both pulsed and mixed i High isolation voltage between the measuring circuit and the current-carrying conductor (AC2.5KV) i Extended operating temperature range i 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
