HOxx-NP-

High performance, cost effective, multirange current transducers for DC, AC and pulse currents measurements of 40 ARMS, 60 ARMS, 120 ARMS, 150 ARMS with galvanic isolation. Multirange primary conductor for small current measurements from 10 to 150 A nominal (4 primary pins configuration for each model). Through hole PCB mounting with integrated 4 primary conductor pins. Overcurrent detection set @ 2.93 x Ipn on a dedicated pin. Short response time: 2.5 µs. Access to voltage reference. Low offset and gain drift. Measuring range up to 2.5 x Ipn. Small design (20 (W) x 41 (L) x 27 (H)). High accuracy at 25°C: 1% of Ipn, at 105°C: 3.4% of Ipn. Creepage & clearance distances: 8 mm + CTI 600. Single supply 0, +5 V or 0, +3.3 V. Operating temperature range: -40°C to +105°C. Voltage output (0.8 V @ Ipn). Bandwidth DC... 250 KHz (-3 dB)
