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.

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
