D1029

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 1400FPM express applications. Through the use of tachometer feedback and a secondary current loop, the D1029 acheives 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. "Set-Up" mode provides operation without a tachometer during initial start-up. 7.5A current limited output with generous safety margins for long service life. Included is a UL recognized mutitap transformer to provide correct field power for any job. Also included is a comprehensive step-by-step manual for a smooth and sucsessfull installation.
