AC-3NA is available for 115 or 230 VAC PSC or shaded pole
fans and blowers with current ratings up to 6.0 Amps. AC-3NA
operates at either 50 or 60 HZ power line frequency as selected
by a jumper on the board. It includes a temperature alarm, triggered
if the sensor temperature reaches 10°C above the Control Temperature.
AC-3NA is compatible with temperature sensors P1 through P9
shown on the sensors
page. |

Mounting
|
| To satisfy
safety agency requirements (UL, CSA, IEC, VDE), allow 1/4" (6.3
mm) between the circuit board and chassis ground and 5/16” (8
mm) to any uninsulated secondary circuits. To satisfy UL, a
normal blow fuse rated 10 Amps or less should be used in the
power line circuit. |
