New Products for Power Reliability

Power monitors help manage manufacturer’s branch circuit monitoring system at data-center power cabinets. Basic model measures current only, while “plus” model monitors voltage and kWh, along with other critical parameters. Both modelsallow active and preventive site management at the individual branch current level.

UPS for central emergency lighting systems features 3-phase design and double-conversion technology in sizes from 10 kW to 75 kW and supports all lighting types. Units provide a continuous 90-minute power supply and isolate and protect connected loads from sags, swells, harmonics and other AC-supply problems. VRLA batteries have 10-year design life and recharge in less than 72 hours, and incorporate a battery-management system to extend service life. NEMA 1 enclosure is freestanding with top and side service access and bottom conduit access. For more information on UPS from Staco, click here .

Flywheel power system designed to replace or extend life of lead-acid batteries, providing ride-through for safe system shutdown of most process operations, and handling short-duration disturbances to preserve battery capacity for longer events. One unit can provide up to 25 seconds of ride-through in a 130-kVA UPS, and 40 seconds in an 80-kVA UPS. Units can be paralleled in larger installations. Steel cabinet can be rolled into place and occupies less than 6 sq. ft. For more about UPS from Pentadyne, click here .

Power-monitoring software is now available in web-browser-based system, eliminating the need for purchasing, installing and maintaining software on multiple PCs. Internet Explorer-based product is designed for enterprise- and large-system monitoring. Users receive license for 10 simultaneous connections, with options for purchasing more along with full Microsoft SQL Server 2000 database for data storage. System display also has been upgraded from manufacturer’s previous offerings. For more information about PowerLogic from Schneider Electric, click here .

Main breaker device is designed for residential and light-commercial construction and allow designers to meet expanded service amp ratings with a single unit, instead of dividing service or installing switchboards. Single- and three-phase devices are available for more flexible service applications, as are combination overhead/underground and underground-only feed options. Devices use manufacturer’s R-Frame circuit breaker and feature a split main cover with lifting handles for both utility and customer compartments. Units can be used wherever 240-volt AC maximum multi-metering is specified. For more about breakers from Square D, click here .

Power-warning alert system is mounted on manufacturer’s DIN-rail mount bracket and enables electricians to see the voltage state of every power source within a panel. Alert system is hardwired into power sources to flash whenever hazardous voltage is present in any single/three-phase or DC power system. Units operate from 40-750 volt AC/30-1,000 volt DC and fits into a standard 30mm push-button hole. For more about this system from Grace Engineered Products, click here .

Breaker indicator is designed to warn of possible component failure or overheat of circuit breakers, motors and electrical equipment. Product is a self-adhesive, temperature-recording label with a silver-gray indicator that turns permanently black in less than one second, with +/- 1% accuracy. Packages ship with 30 temperature-sensitive labels and an inspection log. For more information from Wahl Instruments, click here .
