Topstek Current Transducers TPW25A .. TPW250A  
TPW 25A~250A  
Features  
Applications  
Highly reliable Hall Effect device  
UPS systems  
Compact and light weight. Two sensors in one package  
Fast response time  
Industrial robots  
NC tooling machines  
Excellent linearity of the output voltage over a wide input range  
Excellent frequency response (> 50 kHz)  
Elevator controllers  
Process control devices  
Low power consumption (24 mA nominal)  
AC and DC servo systems  
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)  
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  
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
