2.3.1 Conceptual Diagram

The UPS5000-E is an online UPS with a modular structure that facilitates maintenance and
capacity expansion. All the modules are under digital signal processing (DSP) intelligent
control. The power module consists of a rectifier and inverter. The power module converts
inputs into pure, high-quality sine wave outputs by using high-frequency switching.

Intelligent power supply mode allows you to intelligently control the diesel generator
(D.G.) and ensures uninterruptible power supply. The D.G. connection has two scenarios:
use with an AC transfer switch (ATS) and reuse.
The UPS5000-E intelligently manages batteries. The number of batteries is adjustable.
Batteries have a high fault tolerance capability and are easy to maintain. All these
features help increase the battery lifespan by 50%.
The UPS5000-E provides a variety of optional components to address various customer
requirements.
The UPS5000-E is maintained from the front. UPS5000-E-120K-F120 and
UPS5000-E-200K-F200 can be installed back to back or in a row against the wall to save
space.
UPS5000-E-120K-F120 and UPS5000-E-200K-F200 allows you to route cables from the
top and bottom. The UPS5000-E-320K-F320 allows you to route cables from the bottom;
if you install a top entry cabinet, you can also route cables from the top. The
UPS5000-E-320K-F320T supports cable routing from the top.
A user-friendly 7-inch liquid crystal display (LCD) provides the UPS5000-E status and
operating data.
If a surge protection box is configured, the UPS5000-E can provide the 5 kA surge
protection capability. If a surge protection box (20 kA) is configured, the UPS5000-E can
provide level C surge protection.
