Hall Effect Current Transformer HT300M Panel Mouting Description: Magnelab's HT300 is a closed loop Hall Effect Current Transformer suitable for measuring current up to 300 Amp. The product provides an output current of 120 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 • Min. burden resistance • Operating temperature • Linearity • Limit of linearity • Overall accuracy • Output offset current • Zero offset / Temperature • Zero offset /supply variation 300 Amp 2500:1 ± 12 V -5% to ±15 V +5% 25 mA per rail + output current 11 OHMs -10 to +85°C 0.1% of nominal primary current ± 800 Amp peak value (See Note 1) 0.65% of nominal primary current < ± 150 uA at primary current = 0A < 2 uA / °C <5uA/V • Coil resistance • Bandwidth • di/dt following • Delay time 30 OHMs DC to 70 KHz at -1 dB, DC to 115 KHz at -3 dB <100 A/uS < 0.5 uS • Proof stress voltage 7 KVac, rms, 50 Hz for 1 minute, bore to output terminals • Weight 110 grams nominal • Housing Modified Polyphenylene Oxide UL94 V0 • Conductor temperature The temperature or the primary conductor should not exceed 100°C Note 1: At maximum ambient temperature and supply voltage, the duaration of over load currents should not exceed 2 minutes in any 15 minute period.
