HO Series

Main characteristics:

• Three programmable ranges: 8 A_RMS, 15 A_RMS, 25 A_RMS (25 A_RMS set by default)
• Overcurrent detection with programmable thresholds (up to 5 x I_PN)
• Programmable response time (from 2 to 6 μs)
• Up to 4 programmable internal references voltages (0.5, 1.5, 1.65, 2.5 V)
• Access to voltage reference
• Low offset and gain drift
• Measuring range up to 2.5 x I_PN
• Small DC&AC current measurements from 2.67 to 25 A_RMS nominal thanks to multirange configuration
• Small design (12 (W) x 23 (L) x 12 (H))
• High accuracy at 25°C: 1% of I_PN at 105°C: 3.8% of I_PN
• Creepage & clearance distances: 8 mm + CTI 600
• Each model is multi-range according to primary connection configuration
• Programmable low-power mode (Vref disconnecting)
• Programmable fault reporting
• Standby mode
• HO 25 -NPPR & -NSMPR can be digitally programmed by user for some parameters, functions (gain, internal reference used, response time, overcurrent detection level, fault reporting and low-power mode)
• Three HO programmed models are also available in each version (through hole and surface PCB mounting). These are HO 8 & 15 & 25 -NP and 8 & 15 & 25 -NSM models. These programmable parameters/ functions are fixed in factory and can not be programmed by user afterwards.

Features:

• Single supply 0, +5 V or 0, +3.3 V
• Isolation test voltage: up to 4.3KV_RMS / 50 Hz / 1 min
• Through hole (-NPPR or - NP) or surface (-NSMPR or -NSM) PCB mounting models
• Operating temperature range: -40°C to +105°C
• Voltage output (0.8 V @ I_PN)
• Bandwidth DC... 100 to 600 KHz (-3 dB)
