Onsite Power - Products & Services Emerson Network Power has added higher-capacity models to the transformer-free Liebert NX family of double conversion UPS systems with the release of the Liebert NX 225-600 kVA UPS. The UL-listed Liebert NX 225-600 kVA is available for global regions with 480 V, 60 Hz applications, including North America, Central and South America, the Philippines, Taiwan and Korea. The scalable UPS system offers a backup power solution that provides the flexibility to grow incrementally without requiring infrastructure renovations. Softscale technology allows the Liebert NX 225-600 kVA to be sized to current power requirements and easily scaled up to a larger capacity with a simple software key, which is a more reliable method than adding hardware to grow the module rating. The Liebert NX 225-600 kVA transformer-free UPS operates at high efficiency, resulting in lower utility costs. In normal, double-conversion mode, the Liebert UPS operates at 95 percent or higher efficiency during typical 40 percent to 80 percent loading. During Intelligent Eco-mode operation, the Liebert NX 225-600 kVA UPS operates at efficiencies up to 99 percent. This high efficiency operating mode is standard on each system and enables the unit to run on bypass power during customer-defined conditions. This no-break mode is optimized for the Liebert NX design by maintaining power to the rectifier, and keeping the inverter energized and synchronized with the input for fast, no-break return to full double-conversion mode. The Liebert UPS features a real-time, menu-driven touch-screen display panel that monitors a variety of operating parameters, including unit metering and status information. The Liebert NX also can be centrally-monitored and managed through an optional Liebert SiteScan software interface. Data also may be directly output to a network for integration with other monitoring systems, including building management systems. Emerson Network Power Increases Capacity of Liebert NX UPS Product Line Alpha Technologies Ltd. has released the eLimiter, a line power system that enables the distributed antenna system (DAS) provider to distribute 48 V from the DAS Neutral Host to power remote equipment. “Powering the remote nodes, or antenna, is one of the bigger issues with indoor DAS networks,” said Michael Burkhalter, vice president of US Telecom Sales, Alpha Technologies. “In public venues, there is a need to minimize the size and number of antenna and supporting power equipment. The eLimiter solves the power equipment problem by eliminating the need for UPS and batteries at each node. It powers the nodes by using the power and battery system at the neutral host site to safely deliver 48 V over composite fiber/copper cable. In addition to being a green solution, the eLimiter approach raises the expectations for reliability by focusing the battery support and maintenance on the centralized site at the neutral host site or base station.” The eLimiter 100 VA power limited distribution system distributes 48 V power from a centralized power system to deliver current over copper cable pairs to power remote nodes. A single 1RU high eLimiter can support up to 24 remote nodes. The eLimiter is a safe, Class 2 rated device, making it possible for cables connected to the eLimiter to be installed and maintained by any telecom technician. Alpha Technologies Solves the Power Issue with Indoor DAS Networks Caterpillar, Inc. has made several enhancements to its C15 ACERT and C18 ACERT generator sets, improving overall performance and enclosure options. Rated from 410 kVA to 700 kVA (365 kW to 600 kW), these enhancements to the Cat C15 and C18 diesel generator sets are suitable for prime or standby power, and are available in a wide range of configurations with optional equipment. A number of improvements were made to the enclosures, available in either sound-attenuated or high ambient (50°C) configurations. The new enclosed models feature rear-mounted, side-by-side power and control panels and a standard, integral fuel tank base with drip tray, allowing for eight hours of run time at 100 percent prime rating. The top tank plate is now sloped to contain any accidental oil, coolant or fuel spills. An optional integral dual wall fuel tank base for total fluid containment is also available. For added protection to the enclosure, the package has been designed with an all-round, overhanging base frame. The control panel viewing window and access doors for the fuel fill and battery are lockable, improving safety and security. Finally, installation and service are made easy by oversized cable access, an oversized rear door for panel access, and purpose-designed improved dragging and jacking points in the base and an integrated lifting frame (C15 ACERT only). The open configuration models now feature rear-mounted, side-by-side power and control panels, and come standard with an Integral Narrow Fuel tank base with drip tray, allowing for a full, eight hour run time at 100 percent prime. The C15 and C18 generator sets are also fitted with the latest EMCP4 control panels, which provide enhanced performance monitoring capabilities. The EMCP4.1 and EMCP4.2 control panels are equipped with many operational and protection features. Utilizing the EMCP remote monitoring software on a PC in conjunction with the EMPC4.2 allows for up to eight generator sets to be controlled using virtual computer screen control panels. In addition, the open protocol communication ensures remote monitoring compatibility with most building management or supervisory control systems. Caterpillar Launches Next Generation C15, C18 ACERT Generator Sets Subaru’s RGX industrial generators combine features and heavy-duty construction to offer a reliable power source to a variety of end-users. Two models are included in the line, the RGX6500 and RGX7500, providing a mid-range option in Subaru’s industrial generator lineup. Featuring components including overhead cam (OHC) EX series engines, the RGX generators are designed to handle the needs of both large and small applications. The RGX6500 is powered by Subaru’s 12-horsepower EX35 engine and delivers a maximum output of 6,500 watts (5,000-watt standard output rating). Featuring a 7.3-gallon capacity fuel tank, the unit offers 10.3 hours of continuous operation at the rated load. Powered by Subaru’s largest EX engine, the 14-horsepower EX40, the RGX7500 delivers a maximum output of 7,500 watts (6,000-watt standard output rating). The unit offers a 7.3-gallon capacity fuel tank and 7.4-hours of continuous run time at the rated load. Standard on all models, an automatic voltage regulator (AVR) system provides precise, steady voltage control output, with less fluctuation. Using sophisticated electronics, the system continuously monitors voltage output to ensure steady power flow, necessary for powering more sensitive electronic equipment. The RGX6500 and RGX7500 feature heavy-duty construction and quality components for unmatched durability and reliable operation. A tubular steel frame protects the generator, its engine and components, while a large capacity steel fuel tank and fuel gauge offer long run times and accurate fuel monitoring. Durable electric components feature copper windings with high temperature insulation. Solenoid-actuated AC circuit breakers provide overload protection, and GFCI receptacles help ensure operator safety.
