1.1 HP i 33 10-30 kVA
HP i 33 10-30 kVA series (VFI-SS-111 Type) 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, sudden
drop in voltage, oscillating of decreasing extent, high voltage pulse, voltage fluctuation, surge, inrush current,
harmonic distortion (THD), noise interference, frequency fluctuation, etc. The UPS is designed for different
applications: Personal computers, Drives, PLC communication systems, etc.
1.2 Functions and Features
3Phase In/3Phase Out UPS
3Phase In/3Phase Out high-density UPS system, where the input current is kept in balance.
•
Digital Control
•
This UPS is controlled by Digital Signal Processor (DSP). It increases reliability, performance, self-protection
and self-diagnostics, etc.
Battery Configurable
•
10-30kVA: Designed for 16 to 20 blocks. The battery voltage can be configured as 16/18/20 blocks according to
backup configuration requirement.
Configurable Charging Current
•
The user can set the capacity of the batteries and charging current as well as maximum charging current, via
the setting tool. Constant voltage mode, constant current mode or floating mode can be switched automatically
and smoothly.

Intelligent Charging Method
•
HP i 33 UPS adopts advanced three-stage charging method:
1st stage:
High current constant current charging to guarantee to charge back to 90%
2nd-stage:
Constant voltage to vitalize battery and make sure batteries are fully charged
3rd stage:
Floating mode. This 3-stage charging method extends the life of the batteries and
guarantees fast charging.
LCD Display
With LCD plus LED displays, the user gets UPS status and can monitor operational parameters,
•
such as input/output voltage, frequency and load percentage, battery percentage and ambient
temperature, etc.
Intelligent Monitoring Function
•
Remotely control and monitor the UPS via optional SNMP Card
EPO Function
•
HP i 33 UPS may be completely shut off when the EPO is pressed. REPO function (Remote EPO) is
also available in this series UPS.
