APFC OFFICE series
Standby 400/600/800VA UPS
Patented Design
Product Outlook
APFC Office 800
APFC Office 400/600
What is APFC?
APFC (Active Power Factor Correction) is an advanced
feature on switch power supply (SPS) which leads to better
energy utilization and reduces the size of power supply.
 Lower energy efficiency
 Larger rating components
 Larger size
 Lower cost
 Higher energy efficiency
 Smaller rating components
 Smaller size
 Higher cost
Traditional SPS APFC SPS
What does APFC means to UPS?
APFC SPS
Energy
Imaging there is an energy tank
inside the APFC SPS which has to
be filled up first before the energy
can continuous supply to PC.
Energy
Time
During the start-up period, APFC SPS
requires large energy from UPS which
can make UPS overloaded.
UPS
PC
large energy needed
at start-up
PC (200W)
UPS (400W)
As a result the user has to backup the
PC by UPS with double capacity, just
to fulfill the energy need at start-up.
What does APFC OFFICE do differently
to backup loads with APFC?
Output Voltage
(Other UPS)
Output Voltage
APFC OFFICE UPS
During start-up, output voltage is drawn down
without enough energy to loads
 UPS stops with over-loading error
With patented PWM control, the pulse width is
purposely extended to provide more energy during
start-up, without affecting the frequency
 UPS works normally without over-loading error
Why APFC OFFICE UPS?
No more large UPS for small PC with APFC SPS
just to cover the start-up problem
Cost saving: purchase the UPS with capacity
as large as the loads need
Space saving: no more bulky UPS to occupy
your limited space
