1.1 BRIEF INTRODUCTION
DSP series UPS are mainly applied to computers, data center, administration
center of networks, precision instruments ect. providing high reliable AC
uninterruptible power supply.
The UPS, equipped with dual-conversion design with output isolation
transformer and advanced complete digital control technology, keep on providing the
load with clean uninterruptible power with stable voltage and frequency when the
mains off.
1.2 SYSTEMS CONFIGURATION
ＩＮＶＰＦＣＲＥＣＦＩＴＥＲ
Bypass input
AC input
Battery
DSP series UPS is composed of input & output switches, input & output EMI
filter, rectifier, inverter, output transformer, static switches, battery, maintenance
bypss switch ect.
The main circuit of input power through air breaker input, and get into rectifier
unit by input EMI filter.The rectifier transfer AC power to DC power then get into
PFC circuit to improve UPS input power factor.The partial circuits adopt time delay
soft-start and PFC control technology improving system’s impact resistance and input
power factor and greatly decreasing the harmonic pollution when UPS come back to
energy grids and making UPS use power much better.
Battery connection gets through the switch and contactor, and boost upto DC Bus

6
voltage by PFC. The contactor pull in only when the DC Bus voltage reach upto a
certain value. The battery supply DC power to inverter via the PFC circuit.
Bypass input power through air breaker input, and control output by static bypass
switch.
The whole systems adopts complete digital DSP control. All of UPS inverter
control, phase synchronization, input rectifier control and logic control ect adopt DSP
digital signal manager, which has high precision, fast speed, easy circuit and high
reliability.
The systems has the following working modes.

Figure 1.2，When AC is abnormal or inverter failure, the UPS input rectifier is
off and the DC power from battery is supplied to inverter through static switch and
then output pure and stable AC to load. At the same time, UPS stops charging the
battery.

Figure1.3 Bypass working mode
Figure 1.3 ，when the inverter is abnormal,for example, overload,over
temperature, short-circuit or failure, UPS will turn off the inverter automactially and
turn on the bypass static switch and then the bypass will supply the power to load. At
the same time, UPS is uable to provide uninterruptible power to the load and the
power is just supplied by AC from the bypass.

switch, ouput switch and battery switch and then the UPS is transferred to
maintenance working mode, see the arrow in the figure; it is safe to repair the UPS as
there is no power inner the UPS at this time.
1.4 Function and Features
1.Advanced DSP digit control technology
the inverter control, phase synchronization, input redtifier control, logic control ect…
all adopts DSP digit signal technology with high precision, high speed, high
reliability.
2.High input power factor,green energy-saving power
Input power factor reaches up to 0.99; input current total harmonic distortion
THDI<5%;
3.Wide input voltage and frequency range
4.Excellent network monitor function
With RS232,RS485,SNMP,USB,dry contact interface port available, support
TCP/IP protocol
5.Big LCD display
6.Perfect protection
UPS has input low / over voltage protection, output low / over voltage
protection,overload protection, short-circuit protection, overheat protection; ECO
protection, surge protection ect.
7.Cold start and AC start functin
When there is no AC, UPS can start by the battery set; or when there is no
battery, UPS can start by AC; when AC returns, UPS starts automactically
8.Easy for maintenance
with manual bypass maintenance design; when the UPS is in repair, the UPS can still
supply power to the load.

2.5 The selection of Air switch and connecting wires
The wires for different capactity of UPS should be with different grade,
unsuitable wires or air switch will easily bring dangers. The principle of selection are:
3-5A/mm2for middle and small size UPS, 2.5-3A/mm2for big power UPS. Meantime,
we should consider to control the max voltage drop no more than 3V.
There have input neutral wire for bypass and output neutral wire for UPS power
in the UPS midline system. For three phases in and single phase out UPS, the
cross-sectional area of input null line should be 1.5-1.7 times of phase line.
There have groundings for safe protection and lightning protection in the UPS
systerm, their cross-sectional area should be 0.5-1.0 time of phase line and no smaller
than 6mm2
