Automatic Transfer Switch
100 amp, 120/240V, 1-phase
generator exerciser
When you require a complete basic automatic transfer
transfer switch, we have the solution. The DynaGen Vigilant series is designed to UL
1008 and has all the necessary delay timers, voltage sensing, frequency
sensing, and generator programmable
exerciser clock. Now Made in USA  .
Description
The Vigilant Transfer Switch System. provides automatic transfer of an
electrical load to a standby power supply in the event of a drop or loss of
voltage, on any or all phases of the normal supply. Upon restoration of
normal power, the electrical load is automatically re-transferred to the
normal power supply. All time delays are built in to the control of the
switch and are factory pre-set to simplify installation and startup.
Unique Features
The new redesigned Vigilant series switch has many unique features not
available on other switches, or only available with upgraded more-expensive
models. Compare with the competition...

NOTES:
1) The start time delay prevents nuisance generator starts during momentary utility
power variations; transfer time delay allows generator set to stabilize before load is
applied; retransfer delay prevents needless power interruption if return of utility power
is momentary; stop delay allows gradual generator set cool down; undervoltage sensing of
utility supply provides reliable starting of generator set during brownout conditions.
2) This switch is not service entrance rated. This generally means that you
need a service entrance rated disconnect between this switch and your utility meter.
