Built-in Isolation Transformer
  With built-in isolation transformer, the UPS will offer full isolation and complete
  common mode noise rejection (N-G = 0) for connected precious equipment.
  It becomes an ideal power source with 100% protection against unexpected
  AC Power problems.
Power Distribution Unit (PDU) for SUI-Tower Type :
The module of Power Distribution Unit (PDU) is assembled on UPS rear panel.
When UPS is sent for maintenance, it is not necessary to unplug all connected
devices. Please set UPS on Bypass mode and then remove the metal cover on 
Maintenance Bypass Switch. After metal cover is removed, a rotary switch is
seen. Switch the rotary switch from "INV" to "MAINT" and afterwords screw out
all screws on PDU. After all screws are removed, it is okay to dismantle PDU from
UPS rear panel. After PDU is dismantled from UPS rear panel.  UPS can be sent
for maintenance individually, PDU works as power strip and continues to supply
power to connected device.
Introduction :
SUI series 1 Phase Commercial Grade On-line UPS make use of the unique AC-DC
conversion circuitry to detect the electricity current and voltage output of utility supply.
The current is input via the high frequency PWM to maintain uniform wave form and
phase in line with the voltage, so as to attain high input power factor over 95% and
avoid generating comparatively significant harmonic interference on the power
network. With the use of the outstanding IGBT as the power conversation component,
the operating frequency of the Inverter of UPS is capable of reaching tens of KHz,
due to the high frequency operating characteristics of IGBT.  Higher working efficiency
of the Inverter also improves the overall efficiency of UPS.  Moreover, higher inversion
frequency reduces the noise of the Inverter as well.
