Elcom Network Analyzer model ENA460
Characteristics:
Power quality analyzer ENA460 is based on NI sbRIO (PowerPC processor + FPGA) and signal conditioning for 4 voltages and 4 currents. ENA460 compact aluminium case mounts directly on a 35mm DIN rail.
Key features:
- 4 galvanic isolated voltage inputs with antialiasing filters
- 4 galvanic isolated direct current inputs with antialiasing filters
- Adaptive sampling frequency
- Dimensions: 170 x 230 x 120mm (H x W x D)
- A/D converter with 16-bit resolution
- Optional galvanic isolated digital inputs and outputs
- Consumes less than 20VA
- No rotating parts for high reliability
- Operating system VxWorks
ENA460 analyzer fully complies with the IEC 61000-4-30 standard, class A.
