ASCO Power Transfer Load Centers

Streamline with an Integrated SystemASCO Power Transfer Load Centers: Power Continuity And Surge Protection In a Single Enclosure

ASCO 7000 Series Power Transfer Load Center with quick-connect Cam-Lok assembly

and Telco section

Product Features ASCO Series 300 and 7000 Power Transfer Load Centers integrate the most commonly specified com-ponents required to help protect system loads from power outages, sags, surges and over-current pro-tection of load conductors. • A world-class ASCO

Automatic or Manual Power Transfer Switch with digital mi-croprocessor controller.

• Load Distribution or Load Center

that distributes 240/120 volt single phase or 208/120V three phase power to site equipment.

• Main and alternate source circuit breakers that provide over-cur-rent protection and disconnect for convenient and safe service-ability.

• Transient voltage surge suppres-sion for normal and emergency power sources.

• Optional ASCO Thin Web Server for 24/7 remote connectivity with a single site or a network of sites spanning the country.

•Optional Telco cabinet for cus-tomer mounting of telephone equipment.

Product Benefits Integrating components and factory wiring them into one enclosure significantly reduces installation time, overall cost and minimizes on site problems and installation errors.

The shallow, space saving design provides easy access and service-ability. The load center is service entrance rated, listed to UL 67 and is available in a UL Type 1 (indoor) or UL Type 3R (outdoor) enclosure.

When power fails, the automatic transfer switch follows user-set time delays to start the genera-tor, transfer the load to the gen-erator, reconnect to utility power when it returns and shut down the generator after generator cool down. An automatic engine exerciser tests the generator with or without loads.

The load center also has a con-trols and status indicators panel. Controls include a test, time de-lay bypass and engine exerciser switches. LED’s indicate transfer switch position and source avail-ability status.

Multiple power-related cabinets and components con-sume valuable floor and wall space inside equipment shelters at communications sites.

The area they demand, including mandated clear-ances, can total as much as 23 sq. feet for 200 or 400 Amp Services.

And when multiple components are located outside of shelters, the potential for leaks and weather-induced damage is that much greater.

With space at a premium and more advanced com-munications technologies being installed at sites, it makes sense to streamline and simplify site power protection and distribution strategies.

Why Manage Multiple Components?Integrating components into a single, space-saving cabinet is the answer. The components operate as a power transfer load center.

Benefits include reducing installation costs, time, potential errors and improved reliability.

ASCO Power Technologies offers a comprehensive family of power transfer load centers that can be tailored to virtually any site.

The 7000 SERIES Microprocessor Based Controller is used with all sizes of PowerTransfer Switches from 30 through 4000 Amperes. It represents the most advanceddigital controller in the industry and includes, as standard, all of the voltage,frequency, control, timing and diagnostic functions required for most emergencyand standby power applications. Because of severe voltage transients frequently encountered with industrialdistribution systems, the microprocessor logic board is separated and isolated fromthe power board as shown below. This improves electrical noise immunity performance and helps assure compliance with the rigorous transient suppression standards high-lighted below.
