Site Power Monitor | Newmar

Supplier: GFS Power

For the remote monitoring of critical site conditions.


Sensor data

  • DC bus/battery voltage
  • DC system amperage/battery charge-discharge current
  • AC voltage
  • Ambient temperature
  • Dry contacts/Alarms


  • Programmable alarms
  • Data logging
  • Ethernet camera

Reporting via:

  • Internet – software Included
  • E-mail
  • Mobile phone

Web-enable and integrate intelligence to any site's AC and DC power and sensor system for 24/7 monitoring, alarm condition notification, and data logging of vital 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 and other conditions 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 at communication sites, base stations, outdoor-enclosure via Ethernet or Wireless connection.

The palm sized unit can be rack, DIN-rail, or wall 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, PDA, and mobile phone.

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.
