Designed for continuous current operation and switching of electrical loads between primary
power and standby generator sets.
PowertechTM automatic transfer switches, signal generator set startup, automatically
transfer power, and return the load to the primary power source once the utility returns
and is stabilizied.
High-pressure silver alloy contacts withstand thousands of switching cycles without
burnign, pitting orwelding. The require no routine contact maintenance and provide 100%
continuous current ratings.
In utility-to-genset applications, the control system utility and genset power. When
utility power falls or is unsatisfactory, the switch starts the genset and transfers
critical loads to the genset. The switch automatically tranfers loads back to the utility
when utility power returns.
In utility-to-utility applications, the control system the primary utility source and
transfers the critical load to a secondary utility source when primayr power fails or is
unsatisfactory. The switch automatically transfers loads back to the primary source when
power is restored.
In genset-to-genset applications, the transfer switch automatically controls multiple
genset, allowing one genset to power the load with another genset as standby. The running
(lead) unit can be selectd manually or may be changed automatically with abuilt-in change
over timer.

Advanced Transfer Switch Mechanism
Unique bi-directional linear actuator provides virtually friction-free, constant force,
straight-line transfer switch action during automatic operation.
PowertechTM Microprocessor Control - A standard, fully featured microprocessor control with
a choice of options. All features, settings and adjuustments are software-enabled for ease
of setup and accuracy. Optically isolated logic inputs and high isolation transformers for
AC power inputs provide high-voltage surge immunity.
Manual Operation - Manual operating handles, shielded termination, and over-center type
contact mechanisms allow effective, manual operation under load (100 - 2500A switches).
Positive Interlocking - Mechanical and electrical interlocking prevent ource-to-source
connection through the power or control wiring.

Main Contacts - Heavy-duty silver alloy contacts with separate arcing surfaces and
nultileaf arc chutes are rated for total system transfer including overload interruption.
Easy Service/Access - Plug connections, dorr-mounted controls, ample access space, and
compatible terminal makings. The control is field programmable.
Product lines, Accessories and Services - DP offer a wide range of accessories and services
to precisely suit your requirements.
Certifications - Powertech Transfer Switches are certified to a wide range of standards.
Warranty - Powertech offers single-source responsibility at both the factory and
distributor levels for warranty, service, and parts support.
