MEAN WELL XLG-240-48-ABV and XLG-320-48-ABV Poultry LED Power Supplies are flicker-free LED dimming power supplies with constant voltage output, which lowers the chance to panic animals towards the changes in environmental light and improves their growing or egg-laying rates. Due to the varying sizes of animal farms, poultry lighting is currently designed with constant voltage fixtures and wired according to the scale of the site for most. Thus, length restrictions would also need to be considered for dimming uniformity. The physiological characteristics of poultry must also be fully considered, as animals are more sensitive to ambient temperatures and flickers of lighting, especially when the intensity, duration, and spectrum of light exposure greatly influences the growth of poultry. Proper lighting can stimulate appetite, increase food intake, and speed up growth. Therefore, it is necessary to use a dimming power supply without flicker to match suitable lighting. In addition to poultry lighting applications, the MEAN WELL XLG-240-48-ABV and XLG-320-48-ABV Poultry LED Power Supplies flicker-free designs are also suitable for areas that have higher requirements for light flicker, such as photography studios, reading spaces, high-end boutiques, and other places that have higher demands for lighting quality.
