INTRODUCTION

The following text is a complete product description, operating guide and basic maintenance
summary of the C
This UPS provides a fully on-line sinewave, completely regenerated for typical non-linear loads.

The SP-MPL series has an output rating of 1250VA. The output power factor rating is 0.7, which
means this unit can deliver up to 875 watts.

This instruction manual is provided with this unit to enhance your understanding of the product
and its applications. Read this handbook carefully in the order it is presented prior to operating or
servicing to avoid harm or damage to you or the unit. The UPS may be referred to in the text as
the SP-MPL Series, Rackmount, etc.

LARY SP-MPL Series Rackmount, digital, uninterruptible power system (UPS).

IMPORTANT SAFETY INSTRUCTIONS,

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be followed during installation and
maintenance of the UPS and batteries.

Always operate the unit within the guidelines and specifications presented to maximize this
system's efficiency and lifetime.

THE SP-MPL SERIES RACKMOUNT

A digital on-line, sinewave UPS is the only total solution to virtually any power problem. It
effectively provides CONTINUOUS POWER, by regenerating the incoming AC to DC and then
back to a highly regulated AC generator. A battery can be provided at the input of the AC
generator to support the load in case of utility interruption. The CONTINUOUS power concept is
a step above the typical power conditioner, in that, power protection is maintained under any
circumstance for the most complete and reliable service to the critical load. This CONTINUOUS
power UPR is designed for the critical, must-not-fail

The Digital Technology (DT) Series rackmount is engineered with the latest Insulated Gate
Bipolar Transistor/Pulse Width Modulation (IGBT/PWM) technology for high efficiency and
reliability. The uninterruptible power system (UPS) is the ruggedized version of the DT family of
products. The electronics are completely governed by an on-board microprocessor. This allows
for not only a digitally processed precision output waveform, but also provides for full interactive
access and control for the user through an RS232 computer port.

Refer to the simplified block diagram, Figure 1, for system description. An AC source is fed
through a double pole breaker for both Hot and Neutral protection. This breaker then feeds the
power circuits and all internal microelectronics. Input voltage is monitored to allow for operation
over a -25% to +35% range of nominal voltage for all load conditions. An input voltage variation
outside this preset window will discontinue power to the critical load.

The input AC, when it is within this specified window is power factor corrected and then sent to
the rectification stage. The DC rectifier stage provides both positive and negative voltages to a
DC rail stage, which then feeds the digitally controlled inverter AC generator. The AC inverter
generator in turn supplies the load. Normally the output inverter generator is at 60Hz
independent of the input line frequency.

applications.

The DT Series on-line topology is unique to other on-line systems in that it is designed to meet
the needs of all non-linear type loads while providing input power factor correction. Computers
and telecommunications equipment, with their switching power supplies are considered a non­linear load, which can be very abusive to most power protection equipment and could decrease
life expectancy. The DT Series is specially designed with a power factor corrected input to
eliminate harmonics back into the power source as well as accept non-linear loads and protect
them efficiently without any output waveform degradation common to other UPR designs.

UNPACKING THE UNIT

Your UPS has been carefully packaged to withstand most abuse sustained during shipment. If
there is significant damage to the carton, or if there is any physical damage to this unit, report this
to your carrier.

It is recommended to save the shipping container and packaging materials for future transporting,
if necessary. Transporting the unit in other than supplied shipping materials can result in unit
damage not covered by the manufacturer's warranty.
