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.

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.
