Overview
The Dialight Medium Intensity White Strobe and Red Beacon is designed for the
lighting of radio towers, wind generators and other obstructions to aerial
navigation.
This design uses LED technology for light output both from the Beacon and
White Strobe. Unlike conventional xenon flashtube technology, little or no
maintenance is required during its lifetime. With output magnitudes of less than
200VDC, working voltages are much lower than with xenon flashtube designs;
therefore, this system represents an advance in safety.
The light operates from a 100/230VAC 50/60 Hz supply. It consists of a White
Strobe section and a Red Beacon section controlled and monitored by a
microcontroller circuit. The red beacon type is determined by the top level part
number selection, either 2,000cd red or 170cd red to meet the Specific
requirements of the German “Wred” specification.
The system consists of a light engine and a power supply box joined by a multi-
way cable. The White Strobe section of the light engine consists of three layers
of white LEDs each driven from its own driver module contained in the power
supply enclosure. The Beacon section consists of 36 high-performance LEDs
driven by another module in the power supply enclosure. In addition, a control
box that may be located a considerable distance away from the light engine and
power supply, such as at the base of the tower, allows the system to be
controlled and monitored.

See section on Switch Settings for additional information
Dimming
The light output can be dimmed to 30% and 10% of full output by means of two
control inputs (DIM0 and DIM1). For 30% dimming connect DIM0 to the Live
input terminal. For 10% dimming connect both DIM0 and DIM1 to the live
terminal. Note that the dimming feature affects both the Red Beacon and White
Strobe.
