Vari Speed® A2000 DC Motor Speed Controllers

Product Details

The Vari Speed® A2000 is compact, rugged, reliable and flexible. Available in 1/2 - 3 HP control rating configurations, the Vari Speed A2000 Series incorporates surface mount technology to reduce package size and improve reliability.

The Vari Speed A2000 may be ordered with isolation, NEMA 12 or NEMA 4 Enclosures.
  • Compact, extremely rugged speed drive for standard permanent magnet or would-field DC motors
  • 120 or 240 VAC line input
  • Nine models rated for 1/8 to 3 HP
  • Available in chassis, NEMA 12 or NEMA 4 enclosure
  • LED status indicators for Power On, Run, and Current Limits
  • Chassis units are UL and cUL listed
Options
Reversing option no longer available. Please contact factory for reversing capabilities.All options available can be installed in field
Isolation
AGBØ provides isolation of non-isolated inputs and allows multiple A2000 controls to be controlled by a single process signal. AGBØ also provides isolated open collector with adjustable time delay for current limit indication, and a speed follower output signal when used with a tachometer.

Operating Conditions

AC Line Voltage:
Rated voltage ±10%
AC Line Frequency: 48 to 62 Hz

Elevation:
Up to 3,300 ft. without derating

AGB0 Isolation Option

Isolation provides isolation for non-isolated input command signals. Provides the A2000 with the ability to accept various process speed signals and isolated tachometer feedback inputs. Includes a minimum speed adjustment, range adjustment and run status LED.

AGB0 Application Data

Speed signal input:
  • 0-10 VDC (0-20 mA DC)
  • 1-5 VDC (4-20 mA DC)
  • 5K, 1W potentiometer (input impedance = 80K ohm)
Run/Stop input:
Contact or solid state (NPN) switching device acceptable

Tachometer input:
20.8V/1,000 rpm; 7V/1,000 rpm

Isolated open collector sinking output signal with adjustable time delay for current limit indication and a speed follower output signal when used with a tachometer. Allows multiple A2000s to be controlled by a single input signal.

Adjustments:
  • Minimum speed (0-50% of motor base speed)
  • Range adjust (0-110% of motor base speed)
  • Limit Time Delay (0.2-2.0 sec)

AGB0 Application Output Data

Current limit indication (overload) with adjustable ignore time.

Output:
NPN transistor capable of switching 24 VDC at 250 mA

Speed follower output signal usable with armature or tachometer feedback

Output:
0-10VDC = 0-100% motor base speed

Maximum current: 10 mA
