ABOUT ME

A major problem with nearly all Transportation Cabinets is limited or no space available

for installing a Battery Back-up System (BBS). Most agencies are forced to pay for an

expensive external enclosure or piggy-back cabinet to provide battery back-up for their

cities. In addition, the Lead Acid batteries currently used in battery back-ups and other

UPS systems are large, heavy, and contain dangerous chemicals which, prior to disposal,

require special handling. Most Lead Acid Battery Back-up Systems need costly routine

maintenance 2-3 times per year. If the routine maintenance is neglected, agencies are

exposed to potential liability issues.

PSI Acquisition, LLC has developed the solution to your Battery Back-up System

problems. The UltraPower-Stealth Battery Back-up System (UPStealth)) utilizes a

unique Battery Pack Panel that can be configured to almost any

shape to fit into spaces and locations inside Transportation Cabinets

not accessible by Lead Acid products. Our

standard UPStealth flexible panels fit into

the Transportation Cabinet’s unused space

between the internal rack and the outside

shell of the cabinet. The battery panel in

this configuration does not take up any rack

space thus eliminating the need for an

expensive external cabinet. In addition,

for NEMA Cabinet users, there is an

innovative UPStealth Shelf Panel which

can be mounted on the top or underside of

the NEMA cabinet shelf. A rack mount

version is also available for other

Transportation Cabinets.

The Main Controller Unit (Inverter) for the UPStealth is only 12” deep (excluding

connectors), 3.5” high (2U), and weighs 18 pounds. There is a 4 line by 20-character

LCD display with an LED back light to display

the status of the system and for setting its

parameters. The Keypad on the front panel has

no moving parts or contacts and is not affected

by even the harshest environmental conditions.

A USB port on the front panel is standard and there is an optional Ethernet / Internet

interface available.

The rear panel of the Inverter provides access to 8-programmable relays which are

controlled by power line conditions and user selected settings of the UPStealth Battery

Back-up System. Each relay has 2-Amp

“normally closed” and “normally open”

contacts. The Relay connectors plug into the

rear panel and can be removed without tools.

There are four circular plastic connectors for

connecting to the UPStealth panels. 42-Amp

pins are used for the battery connections.

Each UPStealth Battery Panel has multiple integrated battery chargers and controllers

that communicate with the Inverter

through a serial communication

interface. Each panel may vary in

weight depending upon the panel

configuration; the battery weight

for a standard 600 watt panel is 37

pounds.

The Inverter can turn each UPStealth Battery Panel ON and OFF and monitors the

condition of each string of batteries through the individual chargers. Because each

UPStealth Battery Panel has its own chargers, adding more battery panels to the system

DOES NOT affect the battery charge time of 4 hours. Up to sixteen panels can be used in

one Battery Back-up System. The standard flexible UPStealth Battery Panels incorporate

a “living” hinge which allows the Panel to be bent and quickly inserted between the

cabinet rack and shell wall without altering the equipment rack. The “living” hinge also

provides the ability to easily remove the battery panel.

PSI spent considerable time choosing the best rechargeable battery chemistry for the

Traffic Industry. Nickel Zinc (NiZn) was chosen for its:

•! High energy density and performance

•! Environmentally friendly materials

•! Durability and overall safety of the cells

•! Life, which is twice as long as Lead Acid Batteries

NiZn batteries have no transportation restrictions, are certified as recyclable by the

Rechargeable Battery Recycling Coalition, and are RoHS

Compliant. There are no restrictions with regard to the

disposal of expired cells. NiZn batteries will not explode,

catch fire, nor outgas hazardous fumes even when abused . In

addition, the NiZn rechargeable chemistry does not dissipate

any significant heat.

OPERATION

The

UltraPower-Stealth Battery Back-up System is an intelligent

multiple processor power control system. Each 48 Volt string of cells has its own charger

and monitor board that is controlled by the Inverter. Each charger is individually

addressable and controllable by the Inverter. The Inverter can turn all or just some of the

battery chargers on and off in addition to being able to turn the output of each battery

string on and off. Status information for each battery string in each battery panel is also

available through the serial interface.

Each charger monitors the temperature of its battery string and adjusts the charging

voltage and current to the cells. The charger also monitors the current going out of the

batteries and can turn off the battery pack output if it determines the load is too high. By

monitoring the voltage and current into and out of the battery, the charger can determine

the capacity of the battery string and relay that information to the Inverter. The battery

charger can also turn on an optional heater if the temperature of the battery pack gets too

low.

The Inverter controls the operation of the UPStealth BBS. The Inverter monitors the

power line continuously to determine whether it is supplying the correct power to the

Transportation Cabinet. When the Inverter determines that the AC Power Line does not

meet pre-set parameters, the Cabinet power will be switched to the battery power.

The UPStealth Inverter is an Intelligent Two-Stage Battery Back-up System.

• Stage One runs continuously. It contains a transient protection circuit which reduces

the voltage spikes on the AC power that is coming into the Cabinet. The transient

protection can handle 480 joules of energy and 39,000 Amps peak current. In

addition, the input circuit contains an RF filter, which provides attenuation of line

noise of 25 dB at 10 KHz, 65 dB at 100 KHz, and 100 dB at 1 MHz.

• Stage Two switches over to the battery power when the power line is outside user

programmed parameters. The AC Line voltage thresholds where the UPStealth

switches over to battery power can be set from the front panel of the Inverter or from

a PC connected to the USB port. The depth of discharge (DOD) can also be

adjusted, allowing the user to maximize battery back-up time while preserving

battery life. The UPStealth can also be programmed to switch over to battery power

based on the time of day to assist with Utility costs during peak energy cost periods

each day.

The UPStealth Inverter has 8-programmable relays it can control based upon several

different parameters including:

• Power Failure

• Low Battery

• Time of Day

• Temperature

• Time Delay (e.g. for Flash)

• On Battery

These can be used to provide status information to the Traffic Controller or control the

Cabinet Flash circuit. Fans, lights, or other enunciators can also be controlled by these

relays.

The Inverter Front Panel Display normally shows the power line voltage, cabinet current

consumption, and battery status. Because the UPStealth is an Intelligent System, it can

monitor the cabinet

Voltage and current,

and knows the battery

status. It can calculate

the back-up time that is

available at any given

time without any input

from the user. An event log is incorporated in the Inverter, which shows a history of the

events that have occurred to the cabinet power. The total number and length of power

failures are stored in memory and can be displayed on the Inverter front panel or

uploaded to a PC. The relay functions are programmable from the front panel of the

Inverter and/or by a PC using the USB port. A user-friendly, menu-driven display and

keypad are used to set parameters in this Intelligent BBS. The keypad selects the menu

and the display shows the options to select.
