AC drive

The Square D S-Flex enclosed AC drive is designed for new and retrofit HVAC applications and features the Telemecanique Altivar 31 drive. The AC drive includes all mounting hardware and wiring connections, is NEC 2005 Art. 409-compliant, and comes with a Mag-Gard circuit breaker for resettable overcurrent and branch-circuit protection. It is available in two base enclosure sizes in 1 hp to 20 hp at 460V ratings that require NEMA Type 1 general-purpose enclosures.

Wireless building automation system

APOGGE wireless field-level network is based on a redundant mesh topology. The network was designed to provide flexible, efficient control of heating, ventilation, and air conditioning (HVAC) systems in challenging building environments. The network was also designed to find a different transmission path if obstacles prevent the signal from finding its target.

Non-cycling lamp

The high-pressure sodium, non-cycling Ceramalux lamp eliminates the unwanted “cycling” that causes outdoor lamps to turn off and on at the end of life. When the lamp reaches its end of life and goes out, it will stay out. The lamp contains 90% less mercury than the company's standard Ceramalux high-pressure sodium lamp and passed the EPA's TCLP test for non-hazardous waste. It's average life is 30,000 hours, and it's available in two shapes and five wattages from 70W to 400W.

Lighting fixtures with five-tap ballasts

Five-tap ballasts are now an optional feature on many of this company's lighting fixtures outfitted with metal-halide, pulse-start metal-halide, and high-pressure sodium lamps. This new feature will allow users a solution for each of the five U.S. voltage systems: 120V, 208V, 240V, 277V, and 480V. The company claims the new feature will reduce stocking requirements for the end user, distributor, and contractors involved in fixture installation and maintenance.

Self-testing exit and emergency lighting

The Smart-Check feature on this company's emergency and exit products is a preprogrammed microcontroller that continuously monitors the unit's operational readiness, automatically performs code-mandated battery discharge testing, and communicates service status and alerts via a dual-colored LED indicator. The microcontroller also performs the required NFPA 101 LifeSafety Code and NEC-compliant testing of 15-min. battery discharge every 30 days and 90-min. full discharge every 12 months.

Voltage drop software

Lite-Calcs 2.0 is a second-generation software program for calculating voltage drop. The software's new features include enhancements for developing voltage drop calculations for fire alarm control panels, notification appliance circuits (NAC), and auxiliary power supplies. It includes a database for editing, adding, and deleting parts and displays a device description on the screen when a device is selected.

Scopemeter software

AEC Setup Shooter is a software program that communicates with this company's 190 Series Scopemeter. The software can recall, retrieve, and store setups, and send them back to the Scopemeter. It uses a database for access to user diagnostic and setup information. It can send up to 15 setups at one time to the Scopemeter; define job specific setup groups; download setups, screens, and datapoint waveforms from the Scopemeter; save unlimited setups to your database; and create new databases.

Battery tester

The hand-held BZT1 battery tester can test batteries in 10 sec. The tester uses voltage and battery impedance analysis to estimate battery performance and works on 12V and 24V batteries. Custom voltages are also available. The last 20 tests are automatically saved within the tester and can be downloaded to a printer or PC spreadsheet. Self-adhesive markers are also available for recording the test data on the battery.
