SP 1250LX

Built with integrated PIM and programmable display

SP 1250LX Overview

The SP 1250LX products feature an integrated Power Interface Module (PIM) and programmable display. The LX Series are advanced Uninterruptible Power Systems (UPS) that provide clean, regulated Dual Conversion power for controllers and other sensitive equipment inside the cabinet. Available in 3 models in 1250VA/875W, the LX Series has an operational temperature range of -40˚C to +74˚C (-40˚F to 165˚F), and is compatible with most existing traffic cabinets, meeting all NEMA temperature specifications. Optional NEMA 3R Type II and Type III cabinets are available. The SP 1250LX provides full operation in intersections with all LEDs. Advanced communication features allow monitoring, configuration and control of the system over RS232, modem or network connections.
