Series 7000

ASCO



As we become more dependent on the quality and reliability of electrical power, interruption or complete loss of power can create serious and even crippling financial losses, or impose dangers to life and safety.

ASCO Power Technologies (ASCO) provides the solutions to handle the transfer of critical loads to emergency sources reliably and with state of the art products. Using ASCO products can mean the difference between a minor inconvenience and a major catastrophe. You’ll find ASCO Power Transfer Switches wherever there is a critical load to be protected.

When flexibility in power switching is a must, ASCO offers a variety of product solutions to meet virtually every application requirement, including distributed generation applications. That’s why the 7000 Series is available in open, delayed, closed and closed soft load configurations. Additionally, switched or overlapping neutral options provide for reliable operation of ground fault protection systems and reduction of voltage transients from unbalanced load switching.

ASCO Power Transfer Switches are the first CE Marked, IEC 609476-1 compliant Transfer Switches in the world which have been certified by a notified body of the European Union.

The Recognized Leader in Power Transfer Switch Technology

• Conventional two-position transfer configuration,

plus closed and delayed transition modes of operation. All configurations available with either automatic or non-automatic control.

• UL listed to 1008 Transfer Switch Equipment &

CSA certified to CSA 22.2 No.178-1978 Automatic Transfer Switches.

• Independently qualified and certified to IEC 60947-6-1,

time withstand current rating for optimum flexibility in circuit breaker coordination (600-4000 amperes).

• Solid, switched, or overlapping neutral conductor options.

ASCO Power Transfer Switches are the standard of the industry. High speed transfer of loads between alternate sources of power, regardless of ampacity size, is achieved by a reliable, field proven solenoid operating mechanism. When combined with a programmable microprocessor controller with keypad and LCD display, they offer the most advanced method of transferring all types of loads, such as motors, electronic drives, UPSs and microprocessor based systems. 7000 Series Power Transfer Switches are available open or enclosed, in ampacity sizes from 30 through 4000 amperes with the largest selection of optional accessories offered anywhere. All switching configurations are available with an integrally mounted bypass-isolation switch and/or rated for use in service entrance applications.

Delayed Transition Transfer Switching

Fig. 3: Four pole, Delayed-Transition

Transfer Switch rated 2000 amperes.

ASCO Delayed Transition Transfer Switches are designed to provide transfer of loads between power sources with a timed load disconnect position for an adjustable period of time. Applications include older style variable frequency drives, rectifier banks, and load management applications.

• Available 150 through 4000 amperes.

• Utilizes reliable, field proven solenoid operating

mechanisms.

• Mechanical interlocks to prevent direct connection of

both sources.

• Indicator light (16mm, industrial grade

type LED) for load disconnect position.

• Adjustable time delay for load disconnect position.

Closed-Transition Transfer Switching

ASCO Automatic Closed-Transition Transfer Switches feature main contacts that overlap, permitting the transfer of electrical loads without power interruption. The switch transfers in a make-before-break mode if both sources are within acceptable parameters. Control logic continuously monitors source conditions and automatically determines whether the load transfer should be open (conventional non-overlap mode) or closed transition. Available 150 through 4000 amperes.

Closed-Transition Transfer within 5 electrical degrees is achieved passively, without control of engine generator set. Therefore, no additional control wire runs are required between the ATS and engine generator set governor. Plus, protective relaying may not be required under normal operation since the contact overlap time is less than 100 milliseconds (consult your local utility on protective relay requirements).

Failure to synchronize indication and extended parallel time protection is built-in to all 7000 Series closed transition controls to prevent abnormal operation.

The 7000 Series Microprocessor Based Controller is used with all sizes of Power Transfer Switches from 30 through 4000 amperes. It represents the most advanced digital controller in the industry and includes, as standard, all of the voltage, frequency, control, timing and diagnostic functions required for most emergency and standby power applications.

Because of severe voltage transients frequently encountered with industrial distribution systems, the microprocessor logic board is separated and isolated from the power board as shown below. This improves electrical noise immunity performance and helps assure compliance with the rigorous transient suppression standards highlighted below.

The ASCO Power Manager is a microprocessor based metering device that provides real-time measurements of single and three phase power systems. The Power Manager uses digital signal processing technology to measure voltage and current per phase; real, reactive and apparent power, and bi-directional energy. All measurements can be viewed locally with a backlit liquid crystal display and/or displayed remotely with ASCO PowerQuest

or SiteWeb™ products.

Direct voltage input for systems up to 600 Volts AC can be monitored without the use of external potential transformers (PTs). Measures three phase currents and a fourth current input is available for measuring current in the neutral conductor. The Power Manager includes one discrete input for transfer switch position, eight general purpose discrete inputs, and four relay outputs for controlling or monitoring external devices.

Note: The ASCO Power Manager is also available as a separate unit for monitoring electrical parameters anywhere in the power distribution system.

ASCO Services, Inc., provides a wide range of technical services to users of automatic transfer switches in emergency and standby power systems. These services include comprehensive scheduled maintenance programs, modifications, upgrades and emergency repairs. Systems serviced range in complexity from a single automatic transfer switch to multiple transfer switches and engine generators.

ASCO Services is a wholly owned subsidiary and the exclusive OEM service arm of ASCO Power Technologies, the world’s

largest manufacturer of power transfer switching and control equipment. Serving the needs of ASCO’s customers is a major focus; however, ASCO Services is also routinely called upon to perform regular maintenance and emergency repairs on equipment manufactured by others.

ASCO Services offers comprehensive maintenance agreements that detail the preventive care needed to keep emergency power systems ready to respond. A service agreement is an effective way to budget in advance and avoid unexpected expenditures. A 35-

point checklist is utilized to assure critical systems and components are kept in top operating condition. These preventive programs can be customized for national accounts. This customization permits centralcorporate control of costs and scheduling. Periodic reports provide detailed information as to activity, maintenance performed and corrective action.

ASCO Services deploys more than 75 service personnel strategically located throughout the nation to provide 24-hour response in emergency situations. Each region is manned by ex-

perienced personnel who receive ongoing support and training in the newest equipment concepts, design and controls. Because equipment can be utilized for a long number of years, field representatives also receive education on older designs. This knowledge can be invaluable in addressing total system concerns, evaluating problems and providing solutions on site. Service vans are equipped with parts and advanced testing equipment that facilitate these on-the-spot repairs.
