AC-V is a versatile, low cost fan speed control designed
for HVAC applications. AC-V will accept a 20 mA current loop
or 0 to 5 VDC control signal and proportionally control fan
speed over a range of about 4 to 1, as well as turn the fan
on and off. It operates at 60 Hz using a triac phase control
principle. AC-V is available for 115 or 230VAC, PSC or shaded
pole fans and blowers with current ratings up to 8.0 Amps. Because
the control signal is electrically isolated from the fan, it
can be derived from nearly any source. A 5 VDC, 24 VDC or 24
VAC power source is required. |

Features
- Under low speed
conditions, acoustical noise and energy usage are substantially
reduced
- Current rating
to 8.0 Amps in still air at 104°F (40°C)
- Output compensated
against changes in power line voltage
- Control signal
is 0-20 mA or 0-5 VDC (0-10 VDC available) as determined
by jumpers on the circuit board
- Fan speed is
proportional to control signal. Control signal can be used
to switch the fans on and off
- Models optimized
for PSC or shaded pole fans at 60 Hz (50 Hz available)
- Includes an
EMI filter
- Can also control
heaters, compressors, pumps, etc.

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 15 Amps or less should be used in the
power line circuit. |
