New Modular for Faster Availability
What IS the Bulletin 500
Modular Kit?

The Bulletin 500 Modular Kit is the same premium quality Allen-Bradley® brand contactor or starter that you’ve trusted for years, but now with the advantage of stocked, modular components in a single carton. Ordering is easy, with the same catalog number. For example, a NEMA size 1, non-reversing, full-voltage starter with eutectic alloy overload and surge suppression protection is a 509-BOD-17.

The Allen-Bradley Bulletin 500 line of NEMA contactors and starters has solved many customer applications over the years resulting in thousands of different open-type configurations. Providing these different configurations in a timely manner can be a challenge – until now.

Rockwell Automation introduces the Bulletin 500 line of NEMA contactors and starters in a new modular kit format. Modular kits provide maximum flexibility – how you want it and when you need it – in leadtimes of three days or less.

Modular kits are available in NEMA sizes 0...4 for open-type Bulletin 500 top-wired contactors, Bulletin 500F feed-through contactors and Bulletin 509 starters.

ENPHASE MICROINVERTER

The Enphase Energy Microinverter System improves energy harvest, increases reliability, and dramatically simplifies design, installation and management of solar power systems. The Enphase system includes the microinverter, the Envoy Communications Gateway, and the web-based Enlighten monitoring and analysis website.

The Enphase Microinverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system. Distributing the conversion process to each module makes the entire solar power system more productive, reliable, smarter and safer than traditional inverter systems.

The Enphase Energy Microinverter System solves solar power challenges by performing Maximum Power Point Tracking (MPPT) at each solar module. MPPT is an algorithm used to calculate and respond to temperature and light changes detected on a solar power system, and to determine how much power to draw from the module. In contrast, centralized inverter’s MPPT algorithm sees the entire solar power system as a single module, and responds to the lowest production numbers it detects. The Enphase MPPT algorithm works at each solar module in an installation and achieves greater than 99.6% accuracy which enables it to maximize energy harvest at all times, even during variable light conditions. Tests show systems using Enphase Microinverters increase energy harvest by as much as 25% over systems using traditional inverters.
