When you require a complete basic automatic transfer
transfer switch, we have the solution. The AST series is designed to UL
1008 and has all the necessary delay timers and 7-day generator programmable
exerciser clock. It comes standard with fixed voltage dropout relay and
is available with an optional adjustable drop-out voltage relay. And it
is housed in a watertight NEMA 4 enclosure suitable even for severe weather
protection. Made in Canada.
Description
The AST 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.

The DynaGen AST automatic transfer switch has unique features not found
in many other brands of transfer switches including the following...
* NEMA 4 rated enclosure standard for indoor and
outdoor mounting even
in severe weather locations

enamel finish
* hinged front door with padlock provision kit

Positive Interlocking
Mechanical interlocking prevents simultaneous closing of normal and
emergency contacts. Independent break-before-make action positively prevents
dangerous source-to-source connections.

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 device between this switch and your utility meter.
3) * Adjustable settings can be pre-set at factory to your specifications at
no extra charge. Indicate any special settings in comments at bottom of
checkout screen.
