Power management company, Eaton Industries Pty Ltd has introduced a new direct current (DC) energy meter recommended for telecommunications and infrastructure operators who monitor and bill co-located tenants for DC energy consumption.
Eaton’s DC energy meter features a colour LCD front panel interface and is designed for power systems operating at 24V and 48V DC. It 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 also offers 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. The sensors are powered from the DC energy meter to simplify installation and deployment.
Key features of Eaton’s DC energy meters include multiple physical interfaces provided for communications with the meter - Ethernet, RS232 and USB; built-in web server allowing users to easily access the data and make system configuration changes; data accessible by customer’s SNMP based monitoring systems; USB port for local access for management and configuration; security handled via several login, front panel and authentication options, including remote radius user management; and facility to establish alarms to alert the owner if sensors fail or power circuit errors occur.
A number of spare I/O ports have been provided to manage or control site parameters such as temperature, door alarms or intrusion detectors. The DC energy meter is powered by dual 24/48DC sources to ensure maximum system reliability.
According to Darren Salter, Telecom Solution Manager, Eaton, real time measurement and monitoring of energy consumption is essential for building asset owners, but it is also a business imperative for owners and operators of communications networks and data centres. He adds the new DC energy meter offers a versatile solution for organisations that have to manage power systems, which not only deal with fluctuating demand but also future changes in demand.
