performing the Real Time Processing of a large amount of system
data. The DSP control provides maximum performance in terms of
: |
- Voltage
accuracy, essential for supplying non-linear loads.
- High power
efficiency >92.5% overall & 98% in Eco-mode.
- Maximum
reliability through unique packaging and thermal management.
|
| EVEREST UPS
system is designed to provide the most suitable features and characteristics
: |
- Wide input
voltage tolerances typically ±20%.
- High power
factor.
- High performance
when supplying non-linear loads.
- Parallel
systems for redundancy and field upgrade of power capacity.
- Very high
efficiency.
- Compact
in size-smaller foot print for same power.
- Very low
acoustic noise- <50dBA.
- Low heat
dissipation-losses below 7.5% at full load.
- Low running
costs : High efficiency and Eco-mode function.
- Reliability
& long life of the battery ensured by ‘Neo-Charger’.
|
| Neo-Charger |
Considering
the importance of the battery in a UPS system and to maximize
its lifetime, EVEREST uses a special technology termed ‘NEO-CHARGER’.
Neo-Charger Technology enables : |
- Intelligent
management of the battery recharge by a separate charger.
- Automatic
charging voltage control according to ambient temperature.
- Very low
residual, ripple voltage.
- Battery
availability controlled by automatic test.
- Protection
against slow discharge.
- Protection
against over current charging.
- Automatic
battery test with indication of battery condition.
- Read-out
of all the battery parameters on display- remaining back-up
time, charge level, current and voltage

| On-Line,
Double Conversion, Parallel Redundant Technology |
True
on-line, double conversion technology of EVEREST series UPS ensures
highest power protection and maximum reliability for the most
critical applications. It is composed of : |
A
Rectifier : It converts the AC Line Power Input into a DC
Power supply for the inverter. As it works directly with the Line
Voltage, it is provided with an RFI filter for eliminating radio
noise interference, a circuit for power factor correction, and
protections against over currents and Deep Battery Discharges. |
A
Separate Battery Charger : It intelligently manages the battery
recharge, and maximizes the lifetime of the battery. |
An
Inverter : It provides a low distortion, high stability and
noise-free Output Supply Voltage, by converting the DC voltage
supplied by either the rectifier or the battery. The inverter
uses the latest DSP controlled PWM Technology using New Generation
IGBTs (Insulate Gate Bipolar Transistors) switching at high frequency. |
A
Static By-pass : In case of excessive overload or unlikely
event of failure, Static by-pass switch transfers the load directly
to the commercial Line automatically and without any interruption. |
A
Manual By-pass : Prevents supply interruptions to the load
during service and maintenance. If the manual by-pass is activated,
the load is powered from the commercial line and the UPS is effectively
isolated from the power supply circuit and can be switched off.
It ensures continuous power supply to the load while the necessary
testing or repairs are made on the machine without any risk for
the user. |
| Eco-Mode |
The
ECO-MODE function allows cost-effective operation of EVEREST systems.
In this mode, the load is supplied from the commercial line. In
the event of line failure, the inverter takes over the loads and
provides supply continuity to the connected systems. |
Operation
in Eco-Mode can be selected manually or programmed through the
software. As an example, a user, automatically and from a remote
PC, could program night-time operation of the UPS in Eco-Mode
so that day-time operation is in "On-line" mode when
power to the more critical loads is needed. |
| Harmonics
Suppression (THCDL) |
This
solution significantly reduces the harmonic distortion (as low
as 5%) of the input current to the UPS. This allows the UPS to
take sinusiodal current from the input line supply even with highly
distorting loads connected, as its output. |
| Communication
and Remote Control |
|
|
EVEREST
provides a complete range of solutions to communicate not only
with the users or service personnel, but also with the computer
systems themselves. |
The
New Crotech UPS Graphic Software sets up dialogue between the
computer and your EVEREST Series UPS system. It easily integrates
with all the major Operating Systems, such as WINDOWS, NOVELL,
OS/2, UNIX”. |
|
 |
Automatic
Shutdown of Servers :
When the input line supply is down, the users are informed of
the UPS working on battery back-up. Before the end of the battery
back up, UPS software performs an automatic shutdown of the current
applications and turns off the inverter. |
|
| EVEREST
Remote Monitoring and Management :
Our UPS Software allows the remote monitoring of EVEREST. The
user can program the automatic battery test and draw up statistics
concerning the quality of the incoming and conditioned outgoing
Power supply. |
EVEREST
Management in an SNMP Network :
The SNMP agent of UPS Software allows the EVEREST system to be
monitored like any other computer peripheral. It provides remote
and real-time access for information on the EVEREST running status. |
| Communication
with BMS |
|
|
The
serial link allows the communication with BMS system (Building
Management Software Systems). All the information of the EVEREST
database - status, measurements and alarms - are transmitted via
an RS485 serial link. |
|
 |
| Remote
Mimic and Control Panel |
The
remote mimic diagram of EVEREST UPS and the control panel, installed
in the user’s premises or in the vicinity of the computer,
informs the user about the running status of the EVEREST System
as well as the voltage, current and frequency measurements. |
| Maintenance |
| Given the vital
importance of UPS, offering prompt Quality Service is just as important
as the Product Quality. |
In
order to increase reliability by reducing MTTR (Mean Time to Repair)
by way of simple and rapid maintenance, the EVEREST UPS incorporates
: |
*
A socket enabling maintenance engineers to connect a personal
computer to carry out checks, diagnostics and configuration of
sub-units.
* Modular design for easy access to system components. |
| Remote
Signals |
|
Parallel
Operation |
Remote
status report of the sub-assemblies is offered with Potential
Free Contacts. |
 |
|
Parallel
configuration is based on a modular concept and offers true flexibility.
The system Power can be increased at any time, by adding modules
even after installation and commissioning. |
