for photovoltaïc installationsmeasurement

System Monitoring's ENS26NA is a single-phase GS protection, with integrated 25 A relays. The device is designed for StecaGrid 300 and StecaGrid 500. The tool contains a test key, and an LCD display showing trigger values, current measurements, status and the last 9 grid errors. The equipment can be used as a grid monitoring device for single-phase systems that use up to 5.7 kW. In addition, this unit monitors the different parameters of public electricity supply, such as over-voltage and under-voltage, frequency deviation and impedance jumps. This monitoring device can also be used as replacement for the permanently accessible disconnection point, according to DIN VDE 0126-1-1.
