The Lightning 505 Regulated Power Supply is a reliable, general purpose access control power supply. It features selectable 12 or 24 VDC 1 Amp output with integrated battery backup, guarding against electrical failure (actual voltage output is 13.8 VDC and 27.6 VDC respectively). This access control power supply is a linear design, so it can work well with sensitive electronics (like powering card readers and door controllers) in addition to powering a selection of access control equipment, including electric strikes and maglocks.
