When supplying power to normally off emergency lights, are there any application issues to consider?
YES. Adjustable transfer on delay and transfer off delay settings are often used. The transfer off delay in particular is often set at 10 to 15 minutes, allowing plenty of time for HID fixtures, if used in the area, to regain their full illumination. These adjustable time delays are standard when the UltraLITE Model ELC’s Timed Normally Off Bus “PLUS” is selected. • Can all inverter systems handle the high inrush current associated with energizing normally off emergency fixtures? NO. Other manufacturers’ products may shut down if the high inrush current exceeds the inverter’s on battery overload rating. This is not the case with the UltraLITE Model ELC! The ELC’s Timed Normally Off Bus “PLUS” option is provided with a user-programmable 0 to 3 second soft start control. This control limits the high inrush current and assured compatibility with various lighting types and manufacturers. • Is the UltraLITE Model ELC a fast transfer lighting inverter system? The answer is NO…its better! Fas
