The EP350 is a Line-Interactive uninterruptible power supply (UPS) with an output capacity of 350W. The EP provides filtered and regulated AC output power of proper voltage to operate traffic signals, conflict monitors, camera equipment, lighting, and additional applications used in Departments of Transportation and Intelligent Traffic Systems (ITS/Traffic). Built-in intelligence provides continuous operation during brownout and voltage spike with Automatic Voltage Regulation. A heavy duty battery charger and robust inverter provide backup power and recharging when line voltage is present. Status monitoring capabilities are provided though the LCD display, serial interface, and optional Ethernet network card for remote monitoring.
