Hall Effect Current Transformer HT500M Panel Mouting Description: Magnelab's HT500 is a closed loop Hall Effect Current Transformer suitable for measuring current up to 500 Amp. The product provides an output current of 250 mA at rated primary current, galvanically isolated from the primary conductor into an external load resistance. Features: • High accuracy • 7 kV proof stress • Fast response Technical and Specification: • Nominal primary current • Turns ratio • Nominal power supply • Power supply current • Burden resistance (See Note 1) 500 Amp (D.C. or r.m.s.A.C.) 2000:1 ±12 V -5% to ±15 V +5% 25 mA per rail + output current To meet linearity limit: 0 to 3 Ohms at ±12 V ±5% , 1.2 to 7 Ohms at ±15 V ±5% To measure nominal current: 0 to 6 Ohms at ±12 V ±5% 1.2 to 12 Ohms at ±15 V ±5% • Operating temperature • Linearity • Limit of linearity • Overall accuracy • Output offset current • Zero offset / Temperature • Zero offset /supply variation • Coil resistance • Bandwidth • di/dt following • Delay time • Proof stress voltage -10° to +85°C 0.1% of nominal primary current ±800 Amp peak (See Note 2) 0.65% of nominal primary current < ± 200 uA at primary current = 0A < 3 uA / °C <2uA/V 20 OHMs @25°C DC to 75 KHz @ -1 dB, DC to 125 KHz @ -3 dB >100 A/uS < 0.5 uS 7.5 KVac, rms, 50 Hz for 1 minute, bore to output terminals General Data: • Weight 525 grams nominal • Housing Modified Polyphenylene Oxide UL94V-0 Note 1 : 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 maximum ambient temperatures. Note 2: At maximum ambient temperature and supply voltage, the duration of over load currents should not exceed 2 minutes in any 15 minutes period
