December 1, 2003 MINNEAPOLIS - Cummins Power Generation
has introduced a new PowerCommandŽ closed transition transfer switch
that features a "blow-on" style contactor for enhanced survivability
in the event of a short circuit or overload. Operator safety is
also improved with a new dead front external manual operating handle
that increases protection during manual overrides. "
In addition to increased survivability and safety,
the new closed transition transfer switch has a speed adjust feature
that works with PowerCommand generator sets for highly reliable
closed transition transfers," says Tom Simon, ATS Product Executive,
Cummins Power Generation. "Like all PowerCommand microprocessor-based
transfer switches and switchgear, this new closed transition transfer
switch is designed with networking capability to create seamless
power systems that deliver safety, reliability, performance and
control."
Available in 125 to 800 amp, two, three- and four-pole
configurations, the new transfer switch can operate in three modes:
closed hard transition, open transition or programmed transition.
A stored-energy actuator provides consistent high-speed transfers
between 50-75 ms, and front access to the connection terminals,
simplifying installation.
For monitoring and control, the new transfer switch
has LED indicators designed to last for the life of the control.
Digital vacuum fluorescent displays feature 2 line x 20 characters,
and ensure long life and operability at extreme temperatures.
The new closed transition transfer switch has the
same user-friendly PowerCommand control featured on existing Cummins
bypass and open transition transfer switches. Operating in closed
transition mode, the control will continually monitor and record
the speed of each transfer. The control will then select the optimal
time to transfer, based on the speed of the contactor and the phase
relationship between the two sources.
