Fixed capacitor assemblies

The StacoVAR ML line of fixed capacitor assemblies is designed to provide power factor improvement for applications from 2 kvar to 200 kvar. Available in 240VAC, 480VAC, and 600VAC versions, the complete assembly is UL 508 listed. Its standard NEMA 1 enclosure includes flanges for mounting on floors, walls, or equipment. Its capacitors are 3-phase metallized polypropylene — self-healing to prevent permanent dielectric breakdown.

Line interactive UPS systems

The Nova AVR 600VA and 1,100VA line-interactive UPSs can be managed remotely from a Web browser or a network management system using the company's network management proxy agent and built-in USB. These UPSs are designed to protect home PCs, networked workstations, and point-of-sale systems against damaging power disturbances. Compatible with the company's Personal Solution-Pac power management software, they feature automatic voltage regulation and line-interactive technology to reduce input voltage fluctuations, saving battery capacity.

AC voltage regulator

The VR120-15 voltage regulation and power distribution system monitors and stabilizes a facility's AC power. The system accepts an input range of 97VAC to 148VAC and provides a processor-controlled, zero-crossing circuitry for ultra-low EMI — 120VAC output (+/- 5V). It includes over-voltage protection, EMI/RFI filtering of the power output, and circuitry to monitor potential over-temperature conditions. It provides nine 120VAC/15A outlets and a front-panel LED bar graph to monitor the incoming voltage and indicate low- or high-voltage input.

Emergency power inverters

PCF-84 and PCF-FT series power-interrupt and fast-transfer AC emergency power inverter systems are designed to provide continuous power for illumination. Available for input and output voltages of either 120V or 277V, these units can operate with fluorescent, incandescent, and HID lighting fixtures, as well as other current-resistive electrical equipment. The PCF-84 power-interrupt system provides 90 min of universally compatible emergency power to fluorescent lighting fixtures and operates both “normally on” or “normally off” power loads. The PCT-FT fast-transfer line voltage to emergency power system prevents interruption of the load during a power failure and provides 500VA to 2,000VA of power.

Power monitor

The Encore series of permanent power quality monitoring systems features configurable designs that allow users to specify instrumentation configurations. The monitors are available with a variety of voltage, current, and data acquisition modules to build from one to four virtual instruments in a single, compact format. It uses the same multi-user Web interface of the company's Signature System and the local color touch screen display (optional) of the company's PX5 family.
