The ST750P family is closely related to the acclaimed ST900 range of Siemens high performance traffic controllers. It is optimised for use as a pedestrian controller and provides Pelican, Puffin and Toucan control strategies at both LV (230V) and ELV (48V) drive levels. The ST750 is due to release in early 2009 and replaces the ST700 controller.
In common with the ST900 controllers, the ST750 family is compatible with the whole range of Siemens street-furniture, including Helios LED signals, LED nearside signals and LED wait indicators, all offering significant power cost savings over conventional signals.
Integrated 230V and ELV 48V lamp switching
Where standard LV lamp switching is required the ST750P provides the ideal solution, whilst retaining the robust and proven design features of the ST700P. For totally ELV installations the ST750P ELV provides a highly innovative 48V system based on the successful ST900ELV intersection controller. The use of ELV, as implemented in the ST750P ELV controller, offers a wide range of benefits, including:
• Increased electrical safety for members of the public in the event of damage to the signal installation
• Increased electrical safety for personnel working on or around the intersection
• Reduced power costs
• Reduced cabling costs
• Improved lamp monitoring of very low power LED traffic and pedestrian signals
