Switchgear Line

The NXAIR-P medium-voltage arc-vented switchgear line has a one-high design that enables venting of gases created by heat build-up during an internal arcing-fault event. Pressure from the expanding gases is directed up and away from the operator. Besides enabling arc venting and providing significant space savings, the one-high design makes it easier to insert and operate a breaker.

Low-Amp Busway

Powerbus 225 provides rapid installation and reliable power distribution. This low-amp busway, rated at 225A and 100A, is designed for conduit and cabling installations. Because it is designed to specifications, built and then tested at the plant, end-users can avoid complicated conduit bending, working and then reworking on the jobsite.

Distribution Panelboard

The ALPN, a compact, rugged distribution panelboard, serves as a centrally controlled switching system for large numbers of branch circuits used in lighting, heating, small motors, and other electrical equipment. The panelboard is engineered to meet NEC requirements for Class I, Div. 1 and 2 hazardous locations. Features include standard breaker operators, along with copper bus bars and Quad-Lead stainless steel cover bolts and optional 1-, 2- or 3-pole breakers.

Overvoltage Protection

The Surge3 provides overvoltage protection of industrial electronics. The device's housing allows for simple installation to protect PLC, HMI/VCP (video control panel), PID controllers, industrial computers, variable-speed drive, and vision systems. In addition, this unit offers the choice of two technologies — MOV and diode — both interchangeable with a plug-in suppressor and common base mount. Computer-matched, high-power cell diodes placed in an advanced diode array offers low clamping with high surge current ratings.

Power Supplies

The SDN4-24-100, SDN8-24-100REDA, and SDP4-24-100 24VDC DeviceNet power supplies meet ODVA requirements for either thick or thin cable applications in process control, industrial control, or building automation. All three power supplies feature an industrial-grade design including indefinite short-circuit, overvoltage, and overtemperature protection, as well as a rugged DIN connector. The power supplies feature large front panels with multiple connection terminations, which result in improved access and easier mounting.

This 300kW diesel generator has been certified to meet the Nonroad Source Emission Standard, CFR 40, Tier II of the Environmental Protection Agency (EPA). By meeting this current standard, the new Model DQAF generator reduces the production of oxides of nitrogen (NOx) by 35%, and lowers carbon monoxide and particulate material emissions by about two-thirds over previous models. Rated at 300 kW for standby and 270 kW for prime power, the Model DQAF is a fully integrated power generation system that offers performance, reliability and versatility in a variety of rental applications. A primary feature of this model is its reliable starting capability combined with fast recovery from transient load changes. The unit is designed to accept its full nameplate standby rating in one step.

Scalable UPS System

The Galaxy PW scalable UPS system allows the purchase of power as infrastructure grows. Protecting from 50 to 300 servers, the UPS system includes six scalable models in power ratings from 100kVA to 225kVA and one of the industry's smallest footprints. It incorporates battery management with automated load testing of batteries. The unit interfaces with SNMP, J-Bus/ModBus, TCP/IP, and RS232-RS485 protocols and is UL-1778 and cUL (Canada) approved. The system also conforms to FCC Class A parts, 15 subparts. It also meets ISO 9001 design and manufacturing standards.
