Topstek Current Transducer TMF500A .. TMF3000A
TMF500A~3000A
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 (16 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)
Applications
ꢀUPS systems
ꢀProcess control devices
ꢀAC and DC servo systems
ꢀMotor speed controller
