2 MAIN FEATURES
2.1 Summary
This series UPS is a three-in-three-out high frequency online UPS.
The UPS can solve most of the power supply problems, such as blackout, over-voltage, under-voltage, voltage
sudden drop, oscillating of decreasing extent, high voltage pulse, voltage fluctuation, surge, inrush current,
harmonic distortion (THD), noise interference, frequency fluctuation, etc..
This UPS can be applied to different applications from computer device, automatic equipment, communication
system to industry equipment.
2.2 Functions and Features
3-Phase In/ 3-Phase Out UPS
•
It is 3-Phase In/ 3-Phase Out high-density UPS system, of which input current is kept in balance.
No unbalance problem might occur.
Digital Control
•
This series UPS is controlled by Digital Signal Processor (DSP); it increases reliability, performance,
self-protection, and self-diagnostics.
Battery Configurable
•
10-20kVA: from 16 blocks to 20 blocks, the battery voltage of this series UPS can be configured at 16 blocks,
18 blocks or 20 blocks according to your convenience.
30-40kVA: from 30 blocks to 50 blocks, the battery voltage of this series UPS can be configured at 32 blocks,
34 blocks, 36 blocks, 38 blocks, 40 blocks, 42 blocks, 44 blocks, 46 blocks, or 48 blocks according to your
convenience.
Charging Current is configurable
•
Via setting tool, the user may set the capacity of the batteries as well as reasonable charging current as
well as maximum charging current. Constant voltage mode, constant current mode or floating mode can be
switched automatically and smoothly.
Intelligent Charging Method
•
The series UPS adopts advanced three-stage charging method—
1 stage: high current constant current charging to guarantee to charge back to 90%;
st
2 stage: Constant Voltage in order to vitalize battery and make sure batteries are fully charged
nd
3 stage: floating mode.
rd
With this 3-stage charging method, it extends the life of the batteries and guarantees fast charging.
LCD Display
•
With LCD plus LED displays, the user may easily get UPS status and its operational parameters, such as
input/output voltage, frequency & load%, battery % and ambient temperature, etc...
Intelligent Monitoring Function
•
Via optional SNMP Card, you may remotely control and monitor the UPS.
EPO Function
•
The series UPS may be completely shut off when the EPO is pressed. REPO function (Remote EPO) is also
available in this series UPS.
