The Total Solution for Add-On Substation Automation

The SATEC ezPAC™ SA300 Series Power Intelligence Unit is an advanced power analysis and control device unmatched in the utility and industrial environments.

The ezPAC™ SA300 Series is a fusion of many Intelligent Electronic Devices (IED) combined into a single powerful unit. ezPAC™ unites advanced control and automation functions, intelligent fault-recorder, power quality and sequence of events (SOE) with automatic analysis and reports. It also offers revenue metering, back-up protection equipment and control devices to provide a complete solution for substation and industrial automation. The ezPAC™ is suitable for retrofit as well as for new utility projects.

This instrument is an ideal cost-effective means to automating an electrical substation with existing electro-mechanical (EM) relays. The ezPAC™ series extends the life expectancy of EM protection relays for many years by providing the information lacking from these highly reliable devices without interfering with the protection scheme.
