Description

This section describes the ADB Airfield Solutions Signature Series.

Ferroresonant, L-828/L-829, constant current regulators (CCRs). These

CCRs are manufactured according FAA specification AC 150/5345-10F.

NOTE: Signature Series is a trademark of ADB Airfield Solutions.

See Figure 2-1. This subsection describes the L-828 CCR. The L-828

uses a Universal Regulator Controller (URC) to provide regulator and

control functions.

NOTE: Figure 2-1 shows a ferroresonant 15 kW/6.6 A L-828 CCR. The

other L-828 CCRs (4, 7.5, 10, 20-30 kW/6.6 A/20 A and 50/70kW) may

differ in size and appearance.
