34. SUMMARY
o Modular Construction for Easy
Customization
o Options offer more features and
functionality
o Extremely high overload/inrush rating
o Very low cost of ownership due to
efficiency and virtually maintenance-free
operation
o Trouble-free operations with no active
devices in power path
o 1% or better output voltage regulation
o Continuous voltage regulation- not crude
step regulation
o Redundant, manual regulation control
(raise/lower switch)
o Individual coil protection- avoid
catastrophic cascade failures
o Gold plated contacts on all coils
o Nickel plated copper bus bar
o Easy, front panel access for
service/installation
o No waveform distortion- no harmonics
added
o Small footprint
o Able to withstand the continuous
vibration of mobile applications
