SP 1250LX

Online UPS with integrated PIM and programmable display

SP 1250LX Overview

The SP 1250LX features an integrated Power Interface Module and programmable display. The LX Series are advanced UPS that provide clean, regulated dual conversion power for controllers and other sensitive equipment inside the traffic cabinet. Rated for 1250 VA / 875 W, with operational temperature of -40°C to +74°C (-40°F to 165°F), the SP 1250LX has been independently tested and certified to comply with NEMA temperature standards as well as NEMA standards for shock and vibration. Compatible with most existing traffic cabinets, the SP 1250LX can be rack or shelf mounted and can be configured with either front or rear power connectors. The SP 1250LX provides full operation in intersections with all LED traffic lights. Advanced communication features allow monitoring, configuration and control of the system over RS232, modem or network connections. Available with battery bus voltages of 48 V or 72 V.
