AE Mains Variable LED Dimmer Control System

Features:

The AE Mains Variable LED Dimmer Control System (VLDCS14) is a self contained power supply and driver for any type of LED light unit up to a maximum power of 14 Watts (LED Load). This self contained unit can be connected to most off-the-shelf dimmer boxes to enable any single of connected group of LED or downlighter lighting units to be powered and dimmed.

This VLDCS has the benefit of:

 - Low Cost.
 - Excellent performance and reliability.

 - Small physical size.

 - Low heat output.

Technical Overview:

The VLDCS14 is suitable for driving lighting systems with various power requirements, including LED retro-fit lamps, LED modules, LED spots, down-lights, and LED strings for retail displays.

The VLDCS14 is fully compatible with current lighting infrastructures and can operate directly from rectified mains power or in combination with a phase-control dimmer. The VLDCS includes a high-voltage power switch and can start up directly from the rectified mains voltage, so no external start-up circuit is necessary.

To support its dimming capabilities the VLDCS14 contains two integrated high voltage witches for bleeder operation and an input that can be used to sense lamp power consumption and activate additional bleeder action when needed.

The VLDCS14 has in-built circuitry to reduce capacitive switch-on losses and optimise valley switching efficiencies for improved effectiveness at low power levels. The VLDCS14 uses duty cycle control and frequency control to adjust the LED brightness. The combination of these two methods produces a dimming curve similar to that of an incandescent lamp and reduces peak current levels.
