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
