Description
ASCO 185 Series Automatic Transfer Switch
The Series 185 Automatic Transfer Switch incorporates the latest technology developed by ASCO for dependable operation in any environment.
When utility power fails for just 1 second or more, the Series 185 Automatic Transfer Switch signals the generator to start. In less than 30 seconds your electrical power is normally restored.
Once the Series 185 Automatic Transfer Switch senses utility power has reached an acceptable voltage level for a period of time, it automatically reconnects your utility power. It then smoothly shuts the generator down after an adjustable 2-5 minute cool down period to extend generator life.
The user friendly control panel also allows you to manually run a test at the push of a button. LED indicators let you know the availability of both power sources and transfer switch positions.
