|This is a low voltage mini LED sign which looks highly professional and has a smart appearance. It can display one message in red and can be switched to display a different message in green - all within the same space. It runs from 24V DC and can be powered and switched automatically by a control system or can be manually switched and powered using Lasermet's 24VDC power supply. The Power Supply Part number is PS-LEDS-RG and needs to be ordered in additon to the sign unless you have a 24VDC switchable supply or control system. (See below).
