The 4000 SERIES microprocessor 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 perform-
ance and helps assure compliance with the rigorous transient suppression standards
highlighted below.
