Introduction

The

LP33 S

eries is a robust, high performance

UPS

system

suitable for broad range of mission critical applications
including small data centers, medical, manufacturing,
industrial, telecom and commercial buildings.

Design and Performance

The

LP33 S

eries uses double conversion topology with a

true on-line

VFI

(voltage frequency independent) design.

The hybrid

IGBT

recti

fier provides low input

THD

(total harmonic

distortion) and high input power factor. The

IGBT

inverter

section with transformerless output ensures low output
distortion and fast transient response.

High E

fficiency

The

LP33S

eries can operate in high e

fficiency Eco Mode with

e

fficiencies up to 98% across a broad range of the operating

load range. Eco Mode operation continuously monitors
the output voltage and frequency, and will instantaneously
switch to inverter during voltage or frequency disturbance
to ensure compliance with the

ITI

(

CBEMA

) curve.

Redundant Parallel Architecture

(

RPA

)

R

edundant Parallel Architecture

(

RPA

) can be used

to parallel up to four (4)

LP33

units for redundancy or

capacity. The

RPA

system eliminates single points of

failure by using redundant controls and integral static
switches eliminating centralized bypass cabinets; and
allows field addition of future modules for load growth.

Service

The

LP33 S

eries is fully supported by

GE

’s Global Services

team, providing world-class, 7x24 emergency service
along with preventive maintenance, training, spare
parts depots and application expertise.
