Rack-mount UPS

The Liebert PSI family of UPS systems now includes a 1,920VA model. With the addition of this unit, the line now includes five power capacities to match specific computing needs from 1,000VA to 3,000VA. The PSI is a line-interactive, rack-mount UPS that takes 2U of rack space and can be ordered network-enabled from the factory with the company's OpenComms Web Card installed for integrated SNMP communications.

UPS power system

The BladeUPS power system offers protection from 12kW to 60kW in a 19-in. rack. According to the company, this product does not generate the additional heat associated with legacy end-of-row, modular UPS products. The compact unit can be deployed in a number of configurations — from a distributed architecture (one in every rack) to end of row (up to six units in a rack) to a central system (not on the IT floor, but in the electrical closet). In addition, the company claims the high-efficiency rating is not a large energy cost burden when installed inline with the output of a large, central UPS, or in highly critical computing areas where dual UPS redundancy (2N) is required.

Clamp meter

The Fluke 345 Power Quality Clamp Meter is designed for servicing and commissioning electronic switching loads, including variable-frequency drives, electronic lighting, and UPS systems. Combining the functionality of a power quality meter, oscilloscope, and data logger, the Fluke 345 features a clamp-on design for measuring common power quality parameters. Additionally, it features a color display for viewing measurements in real time and can log data to memory for analysis with the included Power Log software.

Power quality analyzer

Compact and shock-resistant, the PowerPad Jr. Model 8230 single-phase power quality analyzer is intended for technicians and engineers to measure and carry out diagnostic and power quality work on single- or 3-phase balanced load networks. Users can obtain instant waveforms of an electrical network's principal characteristics and monitor their variation over a period of time. According to the company, the multitasking measurement system simultaneously handles all the measurement functions and waveform display of the various magnitudes, detection, continuous recordings, and their display without any constraints.

Double-conversion online UPS

The company has expanded its Smart-UPS RT line to include 6,000VA and 8,000VA models. These double-conversion online UPSs offer tight voltage and frequency regulation, internal bypass, and input power factor correction. The units provide power protection in a 3U rack height with scalable runtime, which is suitable for supporting voice and data networks in a variety of environments.
