The EPS 6000 has set the standard for critical power protection in high-powered
environments. Chosen for some of the world’s most mission critical applications, the EPS 6000’s
field proven performance delivers a level of comfort and reliability only available from MGE.
Featuring aircraft quality construction and MGE’s Digital Power Quality (DPQ) logic, the
EPS 6000 maximizes efficiency & output power quality under all load conditions. Optimized
for 100% nonlinear loads, the EPS 6000 restricts output voltage distortion to under 4% even
on 100% step loads. These rigid performance specifications guarantee computer grade
power quality under the harshest conditions.

EPS 6000 ~ Where Power and Reliability Converge
Digital Power Quality Logic and IGBT Inverter Technology
Digital Power Quality Management
MGE’s unique digital inverter topology takes advantage of the clean switching characteristics
of the new generation of IGBTs (Insulated Gate Bipolar Transistors), resulting in a simplified and more
reliable inverter design. In addition to delivering a practically distortion free (<4% THD) output, the EPS
6000 also maintains precise voltage regulation on all phases even when exposed to large step loads/transients (common when starting distribution transformers and banks of IT equipment), a very unique but

Unsafe Output Voltage
Risk of equipment failure
The EPS 6000 achieves these performance
characteristics by generating the output
waveform using true high frequency digital
pulses (Pulse Width Modulation). Every pulse of
the output waveform is precisely controlled by
MGE’s unique Digital Power Quality (DPQ)
management system. The DPQ system compares
the output waveform to a computer generated
reference sine wave. A feedback circuit then
actively corrects any waveform imperfections
for clean, precision regulated power, and
unprecedented dynamic load control.

Low kVAR Filter: The EPS 6000 offers a low

leading power factor to far below that of conventional input filters. Unlike other contactor based
solutions that disengage the input filter at low
loads, the low kVAR filter is always engaged
and uses no mechanical components.

ensuring that the power factor remains lagging

◗ No Mechanical Switching of Filters
Shunt Inductor Filter: For large UPS systems,
the MGE shunt inductor filter offers no leading
power factor under all operating conditions with
an extremely low THD level. This permits one of
the lowest UPS-to-generator sizing ratios of any
UPS system, and unprecedented UPS generator
compatibility.

The EPS 6000 UPS is equipped with unique
fault tolerant circuitry. Even when exposed
to dead shorts on the output that often prove
fatal to other UPS, the EPS 6000 will recover
without sustaining damage or clearing fuses
and immediately continue to protect the
critical load. Because changes on the load side
of the UPS are increasingly common, output
fault tolerant circuitry is the best protection
against user-induced faults and load side
equipment faults.
