EnerSure 'Bus Monitor' Verifies Power Usage Effectiveness at Michigan Data Center



Liberty Center One, a state-of-the-art data center located in Royal Oak, Michigan, has selected the new EnerSure Bus Power Meter from TrendPoint Systems for its PUE (power usage effectiveness)-based green initiative.

According to TrendPoint Systems, a provider of utility grade power and cooling monitoring devices based in Corona, California, the EnerSure Bus represents a major expansion of its EnerSure Branch Circuit Power Meter product line. EnerSure Bus gathers precise data from IT and cooling loads – amps, volts, power factor, watts, kWh energy — and is the only product that meets ANSI C12.1 standards to provide utility-grade RMS data at the circuit level

The Liberty Center PUE initiative is dedicated to improving and expanding the data center’s monitoring capabilities; and to providing customers with the proper tools for better, more-informed decisions. The EnerSure Bus will provide proactive information and warnings to customers, if their power usage spikes to levels that may trigger circuit overloads, as well as the ability to trend power usage data over time.

The commercial data center—which offers colocation, managed colocation and managed services—chose TrendPoint’s EnerSure Bus after searching for a monitoring product for use in its high-availability environment. The company needed a solution that would fit with its mandate to meet the same type of specifications that Fortune 100 corporations use to manage critical business applications requiring 100 percent availability and uptime.

According to Patrick Turner, Liberty Center One’s CTO, the selection of TrendPoint was “nearly a no-brainer.” He said, “First and foremost, we needed a solution with utility grade accuracy. Next, the EnerSure Bus cost of deployment was easily half that of other similar solutions. Add to that the ease of integrating results into our in-house monitoring systems, and the choice was easy.”

Turner added, “TrendPoint’s offerings for both circuit breaker panel-based and busway-based solutions are the most competitively priced, feature rich, accurate, easily integrated solutions — bar none – that we have seen in the market to date. They provide the right solution for the right price and help us be competitive in the per-rack colo commercial data center space.”

Liberty Center incorporated the EnerSure Busway Power Meter into the design of a new 4,000 square foot expansion space that will come online on December 1, as well as retrofitting the monitoring system for existing customer racks. According to TrendPoint, the EnerSure Bus can be retrofitted onto any busway power distribution system and is the only busway meter that can be installed hot.

Each EnerSure Bus unit can support up to 84 circuits and the product’s flexible configuration monitors circuits up to 4,000 amps, on both 120/208V and 277/480V systems. Proprietary split core current transformers (CTs) are 0.5 percent accurate from 1-100 percent of the rating, giving customers more visibility into their varying circuit loads. Additionally, one, two or three pole circuits can be monitored on the same board and all TrendPoint products support onboard Ethernet communications via SNMP and Modbus, enabling simple communication to most data center infrastructure management (DCIM) platforms.

The EnerSure Bus is available immediately and is priced at $600 per tap.
