Customers invited to visit Western Pennsylvania facility

Warrendale, Penn.  April 7, 2009  Mitsubishi Electric Power Products, Inc. is conducting tours at their Uninterruptible Power Supply (UPS) facility in Warrendale, Penn.

The factory tour program, which began in 2008, is designed especially for clients to help familiarize them with UPS products and technology. Mitsubishi’s hands-on program includes a visit to the UPS warehouse, a tour of its sophisticated testing facility and a demonstration of an operating multi-module system.

Clients are consistently impressed with the display of products on the floor, including the 9900 Series UPS, Mitsubishi Electric Power Products’ latest, three-phase, UPS system with an industry-leading 96.5 percent system efficiency. The highlight for most is a demonstration of the UPS’ ability to accept 100 percent step load with little or no variation in the output waveform.

“Opening the doors to our factory is a way of deepening relationships with our clients and allows them to see our products first hand, something Mitsubishi Electric employees are very proud of,” says Dean Datre, general manager, Mitsubishi Electric Power Products UPS division. “To date, 155 clients have participated in our factory tour program, and all have been very impressed.”
