Hall Effect Current Transformer HT800M Panel Mouting Description: Magnelab’s HT800 is a closed loop Hall Effect Current Transformer suitable for measuring current up to 800 Amp. The product provides an output current of 200 mA at rated primary current, galvanically isolated from the primary conductor into an external load resistance. Features: • High accuracy • 9.5 kV proof stress • Fast response Technical and Specification: • Nominal primary current • Turns ratio • Nominal power supply • Power supply current 25 mA per rail + output current • Burden resistance To meet linearity limit: To measure nominal current: • Operating temperature 0.1% of nominal primary current • Overall accuracy 0.5% of nominal primary current • Output offset current • Zero offset / Temperature • Zero offset /supply variation < 5 uA / V • Coil resistance • di/dt following • Delay time • Proof stress voltage 9.5 KVac, rms, 50 Hz for 1 minute, bore to output terminals General Data: • Weight Modified Polyphenylene Oxide UL94V-0 Note: The maximum burden resistance limit is set by the onset of clipping at the peak of the waveform. The lower limit is set by the thermal limits on the electronics. Higher burden resistances can be used with the lower maximum currents and lower burden resistances can be used at lower maxim
