Direct Current Energy Meter Introduced

William Opalka

Eaton logoEaton has launched a new Direct Current (DC) Energy Meter, which it says is ideal for telecommunications and infrastructure operators who monitor and bill co-located tenants for DC energy and power consumed.

The power management system company’s DC Energy Meter features a color LCD front panel interface and is designed for power systems operating at 24V and 48V DC. The meter measures cumulative kWh, minimum and maximum power, and other parameters of up to eight independent circuits.

The new DC Energy Meter operates standalone and can work with any DC power system, Eaton says.

A range of special non-contact DC current sensors designed for cables and bus bars that can measure current from tens to thousands of amps are also available.

Communications with the meter is via several physical interfaces, including Ethernet, RS232 and USB. A built-in web server also allows users to easily access the data and to make system configuration changes. Customer’s SNMP-based monitoring systems can also access the data. A USB port allows local access for management and configuration.

Security is handled via several login, front panel and authentication options, including remote radius user management. Alarms can be established to alert the owner if sensors fail or power circuit errors occur.

The company says real time measurement and monitoring of energy consumption is essential for building asset owners and operators of communications networks and data centers.
