Power Transfer Switches

Series 300

We Keep Your Power On

fi

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 preventive 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 central corporate 

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 experienced 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.
