Sirius Digital series 500kVA three-phase Automatic Voltage Stabilisers (AVS) protect critical loads form power quality problems including sags, surges, brownouts, spikes and transients, including those generated from local lighting strikes up to 6KV. The voltage stabilisers provide a tightly regulated output voltage and frequency, when the mains power supply is within a defined input voltage window. They have a built-in local communications interface for parameter setting and monitoring and a remote interface for Ethernet or GPRS modem monitoring and communication with the Ortea service centre.
