Web-enable and integrate intelligence of automation and process control power with 24/7 monitoring, alarm condition notification, and data logging of vital electrical functions. All programmable, accessible, and managed via the Internet: TCIP or SNMP. View current conditions and log 30 day history of DC and AC power status at remote sites before dispatching personnel.

The Site Power Monitor is designed specifically for monitoring power supplies, rectifiers, batteries, converters, inverters, UPS, distribution panels, and AC power for automated industrial applications via Ethernet or Wireless connection. The palm sized unit is DIN Rail mounted and is easily adapted to virtually any make of power system via nine sensor input ports which capture and stream critical data via the Internet for analysis and logging of site history. Web page based programs are easily user configured for site parameters with up to 50 desired alarm conditions settings and multiple automatic notification options by e-mail and text message.

Sites without Internet access can use the monitor solely as a data logger that captures and retains 30 days’ data, ready for download to lap top for site history file and analysis of component performance and failure conditions.
