GFC IIA Elevator Regulator | WORLD electronics

GFC IIA Elevator Regulator

GFC IIA Elevator RegulatorGFC IIA replaces U.S. Elevator (Varitron) SSD1, Elevator Industries GMB (Model A), Reliable Elevator GFC, GFCII. Also replaces E-I GMB (Model B) with minor wiring change.

NOTE: Also used in variable voltage controllers made by numerous regional companies, such as, Virginia Controls, Vertitron, Mid-American, Century, etc. See full specification below and an expanded data sheet.

*4′ cable used to interface GFC IIA regulator to system. Complete with 24 pin connector.
• Heavy duty steel enclosure used to mount GFC IIA on site or in control cab. Can also be used with GFC, GFC II, lSSD-1, GMB-A and GMB-B.
** In some areas of the country, UL requires this cover to be used. The bracket protects all of the external potentiometer knobs from accidental bumping once the GFC IIA is adjusted properly.
~ Kit includes all external resistors, capacitors and relays necessary to interface GFC IIA or other generator field control regulators to a motor-generator set.

Supplies generator shunt field, brake excitations. Provides consistent, smooth, stepless acceleration, and stopping functions, and is adaptable to all new or modernized elevator installations up to 350 FPM. Incorporates the following independent controls:

  • High speed
  • Acceleration
  • Deceleration – one floor run
  • Deceleration – multi-floor run
  • Approach speed
  • Level speed
  • Relevel speed
  • Motor field weakening

Solid state design. Furnishes built-in protection from loss of motor field.
All units undergo high-temp environmental testing and burn-in to minimize problems caused by infant component mortality after installation in the field. (Box and cable assembly not included.)
