Shock-resistant rack

EARTHQUAKE-RESISTANT RACK provides a stable platform for batteries, Yuasa introduces a new Zone 4-certified rack for securing its DDS VRLA batteries. Designed for wireless, microwave, central office and other telecommunications applications, the new rack incorporates an easy-to-assemble frame system for quick installation in seismically active areas. Individual cells are encased in dedicated protective steel cases that maintain a constant, uniform compression for the life of the cell. The batteries are available from 120 Ah to 8,000 Ah, and come in custom or standard voltages of 24V and 48V. They are completely front-accessible, come in 29 different sizes and configurations, have a recombination of [is greater than] 95%, and require no watering, periodic equalization, special ventilation or spill-containment.

UPS control

NEW POWER-MANAGEMENT SOFTWARE eases network power management with enhanced support for Linux, Windows NT/2000 and a Win32 console snap-in. Compaq Computer Corp. has enhanced its Power Management Software to ease network administrator tasks for efficiently managing network-wide power regardless of the underlying operating system. This new version allows IT managers an easy way to configure and completely control the enterprise and e-business power framework. The new additions help network administrators configure what network devices should be shut down during a power outage and in what order the devices will shut down. The Compaq Windows NT/2000 Web-enabled module offers the ability to go beyond viewing statistics and to perform all power configuration changes on the fly and in real time. From anywhere on the network, administrators can log into their intranet browser, select the http:// server name, and select the UPS link to gain password-protected access to the fully configurable, power-management options. The new software is backward compatible with all Insight Manager versions.

Power switching

ENSURE PROPER POWER to your essential network components. The TPC2562 is an AC power-distribution unit that combines true redundant input, under-voltage protection and ultra-fast switching. Designed for critical systems, the unit protects against power failures and severe brownout conditions. The TPC 2562 monitors the input voltage and automatically switches to the secondary power source when the primary source fails. Source transfer time is typically 18ms, /- 5ms. Both lines are protected with integrated EMI/FRI protection, inline fuses and surge suppression. The front panel contains alighted on/off circuit breaker and power LEDs, which indicate low-voltage or power-good status for each source. The rear panel contains power output via eight IEC 60320, C13 outlets. The TPC 2562 is designed for a rack mount, and is only 1.75" high, 9.5" deep. The unit has detachable brackets to allow for front, rear or recessed mounting. Vertical mounting brackets are also available.
