AC-VX Motor Speed Control for Motors, Fans and Pumps |
 |
 |
 |
 |
|
| SmartFan
AC-VX is a TRIAC based fan, pump and motor control
designed for OEM applications in HVAC, electronic and industrial control markets. Automatic
detection and adjustment for power factor permits
efficient motor speed control of a wide range of single phase
PSC (Permanent Split Capacitor)
and
shaded pole fans with current ratings up to 8.0 Amps that have been approved for voltage control by the motor manufacturer. The AC-VX digital fan motor speed control accepts 115 or 230 VAC (50/60 Hz) supply
voltages. |
AC-VX proportionally controls fan speed over a range of about 4 to 1, as well as turns the fan off and on based on a control signal input.The
control signal can be from a 20 mA current loop,
0 to 5 VDC, 0 to 10 VDC or P10 remote temperature
sensor input. Because the HVAC motor speed control signal is
electrically
isolated from the fan, it can be derived from nearly
any
source.
This HVAC motor speed control is available with or without a NEMA 4X-rated polycarbonate enclosure.

CAUTION: SmartFan AC motor speed controls are designed for OEM (Original Equipment Manufacturers) and are not intended for end-user or after-market applications. SmartFan AC motor speed controls should only be used with compatible induction motors: Permanent Split Capacitor (PSC) or Shaded Pole. All AC motors must be approved by the motor manufacturer or thoroughly validated prior to use. Attempting to control a fan or motor that is not compatible could cause excessive heating and/or permanent damage to the motor. |

not require a separate low voltage power source
- Compatible
with single phase PSC or shaded pole-motors
that are phase (TRIAC) controllable
- All
connections through terminal blocks
- Control
signal can be used to switch the fans on and off
- Fan
speed is proportional to control signal
