T3X-1 System


Tunnel Lighting Control System
T3X-1 system is a stand-alone based analog control panel.

  • Short tunnel
  • Unidirectional
  • Bidirectional
  • Unidirectional ramp
  • Bidirectional underpass
Inside the T3X-1 System in a NEMA rated enclosure:
(Pre-wired and tested to UL508A (CAN/CSA C22.2.0014-M91)

Major Components

Note:  Incoming power of 120 VAC.  Other source of power can be converted down by the use of transformer inside the T3X-1 system.
