Specification for an Uninterruptible Power System for

Traffic Signal Applications

This specification shall be for a true-on-line, power conditioner and uninterruptible power system (UPS) with battery backup capability designed for transportation and traffic applications for twenty-six (26) intersections. Additionally, seventeen (17) intersections will require the cabinet necessary for house the UPS equipment, which should be included within the bid price. The UPS shall be a totally microprocessor controlled and software driven power system. The inverter shall be in operation at all times supplying clean regulated power (both voltage and frequency) to all loads, at all times. The UPS must be fully power factor corrected and fully functional with any type of auxiliary power generator. The UPS shall be furnished in conformance with the following specification.

System Example:

Clary SP1000SN+ – Uninterruptible Power System

PIM30G – Power Interface Module

OPB100 – Battery Cable

OP72C – Battery Set

336 Type Cabinet with circuit breaker, generator connection, suppression, and led indication (as needed).

1.0 Operation

a. The UPS shall be capable of producing – simultaneously – fully regenerated and regulated, conditioned and true sinewave power with continuous and hot standby AC output capability.

b. The UPS’s inverter shall be on at all times to produce continuous, clean, regulated power to all loads. The inverter shall have a minimum operating efficiency of 92%. The continuous power output shall be provided for signals, controllers and modems, etc.; standby output can also be provided for signals if so required. Up to the maximum load rating, the UPS shall be capable of supplying power to any combination of signal heads, whether Incandescent, LED or Neon, by any manufacturer, regardless of power factor, without overdriving the LED heads which may cause early degradation, low luminosity or early signal failure. Also, a programmable digital delay timer is included for short-term battery run under full cycling operation.

c. Upon loss of utility power the UPS shall utilize battery power in support of the system via a supplied Power Interface Module (PIM). In the normal operation, the UPS shall be operated in the real-time true on-line mode with the inverter supplying power to all cabinet loads, at all times. In addition, the UPS can be operated in hot standby mode with power transfer being accomplished in 100 msec. or less, if required. In the event of UPS failure and/or battery depletion, the PIM will ensure that the UPS will drop out and, upon return of utility power, the traffic control system will default to normal operating mode.

d. The Power Interface Module shall enable removal and replacement of the UPS without shutting down the traffic control system (i.e. “hot swap” capability). Connectors shall be equipped with a “safety interlock” feature.

e. For 170 type cabinets, upon loss of power the UPS shall actuate the existing Flash Transfer Relays (FTRs) and Mercury Contractor (MC) to force the traffic control system into Flash Mode operation.

g. To facilitate emergency crews and police activities, the UPS shall be fully compatible with police panel functions (i.e. “Signals OFF” switch must kill power to the field wiring even when on UPS/Battery power).

h. The UPS shall not duplicate or take over flash operation or flash transfer relay functions.

i. The Traffic UPS shall be capable of providing continuous, fully conditioned, regulated, pure sinusoidal (AC) power to all connected devices such as signal controllers, modems, communications hubs, NTCIP adapters and video equipment at all times.

k. The UPS shall contain two external serial ports located on the front panel (rear panel for 170 applications) of the UPS. The Signal serial port shall provide the user the option to select alarm output functions. These functions shall be open collector type contact closures that the user can assign as signal utility interrupt, low battery and inverter active conditions or utility fail indicate. These signals shall be capable of being interfaced to any manufacturers controller auxiliary alarm inputs or the Power Interface Module (PIM). The RS232 Signal port provides an intelligent interface for connection to optional software systems for monitoring and control, including internet connections.

l. The UPS shall be fully power factor corrected under all operating conditions.

m. Each UPS shall be provided with a CD ROM containing Windows based configuration software.

2.0 Description - The UPS shall consist of three major components, the Electronics Module with a detachable Power Interface Module, and the Battery System.

a. True on line, double conversion, pure sinewave, high frequency inverter utilizing IGBT technology

c. Digital microprocessor based timer for programmable flash command requirements

d. For connection from the Electronics Module to the Power Interface Module and Battery System, dedicated harnesses shall be provided with quick-release, keyed, circular connectors and braided nylon sleeving over all conductors,

e. Local individual LED indicators for AC input, inverter, summary alarm, UPS output, battery status, load levels, with LCD panels for battery run time, and event counters.

h. And be capable of accepting an NTCIP-ready adapter or a Spread Spectrum Radio modem.

i. Two separate DB9F connectors for remote signal alarms and true RS232 monitoring and remote communications.

a. A PIM shall be required to safely insert utility power into the UPS system

b. The PIM shall contain a terminal strip for input and output power connections in addition to neutral and ground connections. In addition, the terminal strip shall also include open collector (relay type) connections for: on battery, low battery and digital flash timer. .

i. The PIM shall include two serial ports with connection to the digital timer. When the serial port on the UPS is connected to the signal serial port on the PIM, loss of utility power shall activate the digital timer. The digital timer shall switch the signal operation from full colors to flash based on flash trigger values

ii. The signal serial port on the PIM can be used to send open collector type contact closures that the user can assign as signal utility interrupt, low battery and inverter active conditions to the signal controller auxiliary alarm inputs.

iii. Optional PIM models shall be available for connection to auxiliary power generators and to provide a GFI outlet.

a. The battery shall be comprised of extreme temperature, deep cycle, AGM/VRLA (Absorbed Glass Mat/Valve Regulated Lead Acid) batteries that have been field proven and tested by the U.S. military.

b. The battery system shall consist of a single string of 6 (1250VA) or 8 (2000VA) batteries of extreme temperature, deep cycle, AGM/VRLA type (Absorbed Glass Mat/Valve Regulated Lead Acid) batteries.

c. Batteries shall be certified to operate at extreme temperatures (from -40°C to +74°C) and shall not require aid of any external devices to cool or heat the batteries.

d. The batteries shall be provided with keyed interconnect wiring harness. This harness shall connect the battery pack to the UPS module. The harness shall be a minimum of 5 feet in length.

e. The interconnect cable shall be protected with abrasion-resistant nylon sheathing.

f. The interconnect cable shall connect to the base module via a quick-release circular connector.

g. For purposes of safety and proper operation, the circular battery connector shall have interlocking pins to prevent turn-on if batteries are not connected, and to shut off the UPS should the batteries be disconnected.

h. Battery construction shall include heavy-duty, inter-cell connections for low-impedance between cells, and heavy-duty plates to withstand shock and vibration.

i. The top cover shall use tongue and groove construction and shall be expoxied to the battery case for maximum strength and durability.
