Bi-Directional Field Regulators


D1029 Closed-Loop Bi-Directional Generator Field Control

The UL recognized, D1029 represents the ultimate in closed-loop Bi-directional generator field control. Fully featured, the D1029 provides a precise "S-Shape" speed pattern , less than 1% speed regulation and complete diagnostics. Operates on geared or gearless elevator systems from freight cars all the way up to 1400 FPM express applications. Through the use of tachometer feedback and a secondary current loop, the D1029 achieves precise control at over a 500:1 speed range. Completely isolated with LED indicators for all functions including comprehensive fault detection and diagnostics. Fully adjustable via six preset speeds, four "s-shape knee"' adjustments, two selectable acceleration and four deceleration potentiometers.
