Affordably Meter, Energy Use by Individual Circuit

You Can Only Manage What You Measure

Data centre managers understand the effect of rising energy use. It means ever increasing operating costs and all the problems of hot spots and power density. The principal of Management By Information states that: “You can only manage
what you measure.” Energy is no different. The problem is that monitoring energy by circuit has been prohibitively expensive. That is, until now.

See and Manage Energy Consumption by Circuit

EnerSure is the centre piece for your organisation’s energy management plan. EnerSure works simply and attaches to each of your facilities circuits within your switchboards with NO downtime. The unit gathers utility data and provides output directly to your server via Ethernet, eliminating distance restrictions.

Modular Architecture to Monitor up to 88 Circuits per Unit

EnerSure’s modular architecture consists of a Processor Module and from 1-4 Data Gathering Modules (DGMs). Each DGM has inputs for 22 circuits. Up to 4 DGMs can be mounted on the Processor Board giving you up to 88 circuits (soon to be upgraded to 120 circuits) with a single complete unit. The Processor Module collects data from the DGMs and makes it available via Ethernet directly to a server.

Multiple Communication Options

 

Ethernet communication can be performed by Modbus TCP, SNMP MIB, & BACnetIP. Serial communication can be performed by using Modbus RTU via RS-232 and RS-485

Precision Data, Not Estimated

EnerSure provides true RMS data with greater than 1.5% accuracy on all the following points for each circuit:

• Current (see actual and peak current for all circuits in your racks)
• Voltage (see peaks and spikes and take early action to avoid trouble)
• Power Factor (the Hidden Cost of Energy)
• Wattage (the amount of heat released from each circuit in your rack)
• Energy (see energy for your all your IT and Cooling loads)

Affordability and Ease-of-Use Make it the Right Choice

EnerSure’s modular architecture and plug-and-play installation make it the right choice for almost any size facility. It installs easily with NO downtime so its the perfect choice for retrofit or new installation.  Because EnerSure continuously samples data with high-grade accuracy, you can use it to manage all the following problem issues:

• High, low and mean amperage, voltage and wattage for each circuit
• Data trending for the last minute, hour, day, month and year for each circuit
• 2 and 3 phase circuits are handled easily and with no additional hardware
