Automatic Transfer Switch
400-1250 amp, 240-480V
 NEMA 3R outdoor, 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...

DynaGen Vigilant Series... the competition...
* galvanized steel enclosure - better corrosion resistance * painted steel
* voltage and frequency sensing on both sources * no frequency sensing on utility source
* voltage, frequency and time delay settings field adjustable * some settings fixed at factory
* interface on outside of enclosure includes exerciser,
   no need to open door		 * must open door to program exerciser
   and perform other functions
* standard 5 year warranty * 1 year warranty standard, extra cost
   for 5 years if available
* normally ships quick from stock * 2-4 week lead time or longer

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.
