Highly Accurate ASIC-based current transducers in Eta technology
Main Characteristics:
- New technology "Eta" combining positive properties of O/L and C/L current transducers
- Use of a programmable ASIC
- 50 & 100 ARMS nominal currents measurements
- 5 years warranty
- PCB mounting
- Measuring range up to 3 x IPN
Features:
- DC, AC pulse currents' measurements with galvanic isolation
- Unipolar supply voltage 0/+5 Volts
- Isolation test voltage: 5 kVRMS / 50Hz / 1min
- Voltage output
- Reference access through an additional pin
Compliance towards:
- EN 50178 for industrial applications such as:
- Home appliances
- Variable speed drives
- UPS's
- SMPS's
- air conditioners
- Using UL94-VO recognised materials
- European Directive EMC 89/ 336 / EEC - CE marking
Remarks:
- Bipolar currents measurements
- Standard models with the additional Ref pin:
- provide access to the internal voltage reference of the ASIC which can then be fed to the reference of an A/D (Analog Digital) converter
- or can receive the external reference (from 2 to 2.8 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics allowing cancellation of the reference temperature drift.
- With SP1 models the internal reference is ratiometric (intial output offset at no primary current at +25°C is equal to Vc/2 volt)
