DOT ITS Power Equipment

When it comes to intersection uptime, power failures are more than inconveniences — they create liability risks and safety hazards for departments of transportation (DOTs), municipalities and their citizens. 

At Multilink, our power supply systems are the backbone of intersection safety. 

Vulnerable traffic cabinets are susceptible to damage from utility instability, brownouts and severe weather events. When emergencies hit, even the most advanced intelligent transportation systems (ITS) can malfunction and lead to issues throughout the community. However, with the right ITS power equipment, you can ensure continuous operation during grid failures and protect sensitive ITS hardware.

Multilink UPS Solutions

Uninterruptible power supply (UPS) systems provide instant, temporary backup for intelligent transport systems. UPS backup systems support devices such as traffic signals, conflict monitors, camera equipment and lighting. If traffic components fail or their voltage fluctuates, your UPS delivers the electricity needed to ensure continuous operation and minimize downtime. 

Our intelligent and uninterruptible power supply systems provide you with a USA-made solution, backed by the U.S. Department of Transportation (DOT) and NEMA TS-2 adherence. 

At Multilink, we provide two types of UPS solutions:

• Line-interactive UPS

• Double Conversion UPS

Line-Interactive Systems

Our EP Series products are best for standard intersections that require reliable backup and voltage regulation. Our line-interactive systems use automatic voltage regulation (AVR) and activate only when the voltage fails or fluctuates. 

The core benefit of our line-interactive systems is that they correct voltage sags and surges without switching to battery power, which can significantly extend their battery life.

Our line-interactive EP series is available in the following models:

• EP 1100

• EP 350

• EP 650

• EP 2200-T

Double Conversion Systems

Our EDP series systems process all power that enters your ITS, ensuring zero transfer time of power during fluctuations. They are ideal for mission-critical systems. Double conversion UPS converts AC to DC and back to AC for perfectly "clean" pure sine wave power.

Double conversion systems are invaluable for expensive intersection controllers and conflict monitors. 

Our double conversion EDP series includes:

• EDP 1000

• EDP 1500

• EDP 2000

Advanced UPS Features

Along with our core UPS solutions, we offer products that enhance their function, such as: 

• Smart Tracker: This IP-ready, GPS-enabled device monitors your power equipment, identifies the location of each voltage issue and enables you to monitor your equipment remotely. 

• Safety Automatic Transfer Switch: This intelligent device partners with our EDP double conversion products to provide automatic power source selection, generator capabilities and alarm reporting via dry contact relays.
