TECHNICAL DESCRIPTION

he Digital Technology S Series Continuous

Power System (CPS) is a revolutionary new

concept in total power protection and

management. The S Series is a

microprocessor-based UPS that now allows the user

to set most of the control feature parameters. By

directly linking a personal computer to the S Series

RS232 port, frequency settings and operation, alarm

signals, load switching, fan operation, etc. can all be

programmed to meet specific application

requirements.

The S Series is a true on-line, continuous power

UPS. In the tradition of Clary products, the

S Series generates the same high quality and

proven reliability to provide the best power

protection available for today's critical applications.

In keeping with state-of-the-art design, the power

electronics are completely governed by an on-board

microprocessor. Given the powerful memory

capability of today's microcontrollers, this

microprocessor has evolved the UPS into an all-in-

one complete power distribution and monitoring

center. Not only is your critical load insured of the

most reliable and constant power available, but the

user may now continuously track status of the

supply components that keep the entire system

operational. Production downtime can now be

virtually eliminated by knowing exactly what patterns

the supply utility power maintains and by knowing

exactly the condition and life expectancy of the

battery reserve.

Reference the block diagram for a simplified

explanation of the system's operation. The AC utility

source is connected to the power and micro-

electronics when the input switch is closed. The

input line is filtered, power factor corrected and

rectified for enhanced performance without

disturbing other equipment that may share the same

utility circuit. In S units, an input isolation

transformer is added. Output transformers, SNMP

adapters and many other options are available.

The microprocessor controls an Inverter Generator

that produces a low harmonic, AC sinewave for

continuous power applications.

When the input AC utility line fails, the battery circuit

within this system takes over to ensure continuous

power.

Only after properly rated power is returned, does the

microprocessor reconnect the input source back into

the system.

The microprocessor is directly tied to an external

RS232 connector port. This allows the user to

monitor and even set some of the operating

parameters. With a simple link to a personal

computer using the DT-UPS2 software program, you

can actually view, on your monitor, the event history

of the power distribution system with the

S Series unit as the central hub. More sophisticated

users may implement the optional SNMP package to

accomplish full Network Power Management.

BATTERY-DESCRIPTION

Your system contains sealed, maintenance free

lead acid batteries manufactured by Enersys,. It

consists of six (6) NPX-25FR, 12 volt 5.0 ampere-

hour (AH) batteries. They are connected in series to

form a 72 volt bus. Batteries are charged with a

constant current, half (0.5) amp charger. The

microprocessor controls the constant current

charging until full charge requirements are met, then

a periodic trickle charge is programmed to the

battery.

A low battery signal is generated during discharge

when the terminal voltage reaches the point where

the microprocessor determines there is 2 minutes

left of battery reserve time. This time can be

changed through the RS232 communications port.

The battery is protected by a system cutoff signal

which is activated before the terminal voltage

reaches an unsafe discharge point.

WARNING:

Never attempt to service batteries,

high voltage exists within the unit which could cause

electrical shock. Servicing of batteries should be

performed or supervised by personnel

knowledgeable of batteries and the required

precautions. Keep unauthorized personnel away

from batteries. When replacing batteries use the

same number and type. The battery pack has a

keyed, polarity sensitive connector. Replace only

with factory authorized replacement parts.
