Features:

DC, AC and pulse currents measurements with galvanic isolation
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)

Standard compliance:

EN 50178 for industrial applications such as:
- Home appliances
- Solar inverters (MPPT)
- Combiner box for solar applications
- Servo drives
- AC Variable speed drives
- Power supplies
- UPS
- SMPS
- Forklift trucks
- Air-conditioners
- Current monitoring
- Welding applications

Remarks:

Each model is multi-range according to primary connection configuration
Bipolar currents measurements when single supplied 0/+5 V or 0/+3.3 V
Programmable low-power mode (Vref disconnecting)
Programmable fault reporting
Standby mode
HO 25 -NPPR & -NSMPR can be digitally programmed by user for some beters, functions (gain, internal reference used, response time, overcurrent detection level, fault reporting and low-power mode)
Thanks to this programmability, a single model in a wide range of circuit configurations can be used simplifying designs and reducing parts stock holdings
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 beters/ functions are fixed in factory and can not be programmed by user afterwards
