Elcom Network Analyzer model ENA300
Characteristics:
The ENA300 Power Quality Analyzer is primarily designed as a cost effective solution for school and university labs. The ENA300 provides programmable signal conditioning (4 voltage and 4 current input channels) and embedded 16-bit A/D converter with a USB interface. The ENA300 has no CPU and therefore must be connected to an external PC via USB interface. The external PC runs the actual ENA300 instrument firmware on Windows XP operating system.
The ENA300 uses the same firmware and provides the same measurement functionality and precision as the rest of ENA series instruments.
ENA300 analyzer fully complies with the IEC 61000-4-30 standard, class A.
