1 Preface
1-1 Introduction
DS-C33 series UPS is one of the industry’s most reliable and stable power protection equipment. It is
fully controlled by DSP (Digital Signal Processor) to ensure high performance and worry free operation
in protecting your valuable equipment from power disturbances. This makes the DS-C33 series UPS
fully compatible for use in computer, precision instrument, banking, manufacturing, and other mission
critical applications.

2-3 Introduction on function of main module
2-3-1 Rectifier / battery charger
(1) Rectifier / battery charger module is using SCR components for transforming AC to DC voltage
and to recharge the batteries.
(2) In Rectifier / battery charger module, double control method to CPLD and DSP are combined to
keep rectifier and battery charger more steady and reliable.
(3) Has complete system for protection from over voltage.
(4) Detection on phase sequence error or single phasing.
(5) Equipped with function to soft start the DC voltage during power up or return of utility power.
(6) Designed with 3 phases and 6 pulses. Optional six phase 12 phase pulse is available.
(7) It supports float charge and equalization charge for maintenance free battery. Floating charge
voltage is DC 420V, equalization charge voltage is DC 430V, floating charge voltage is 410V.
(8) It can conduct self test even in on line mode.
(9) Charging current is controlled by LCD panel setting.
Fig. 2-3-1(actual model assembly diagram)
2-3-2 Introduction to inverter module
(1) Uses IGBT as power component.
(2) Uses high technology DSP to control the inverter module.
(3) Utilize digital control management to prevent discrete component from aging, temperature slant
and reduce the quantity of parts to enhance system reliability.
(4) Integrated A/D signal processing, 12bit resolution and high speed transferring capability.
(5) Reserve communication port for parallel UPS operation, detection of secondary power, ATS
control signal, SPWM testing port.
(6) Highly integrated system, compact and highly reliable.
(7) It is works in coordination with the rectifier, AS-400 interface board, IGBT driver, static switch,
LCD panel, PT board, CT board to convert the utility voltage into clean power.
Fig. 2-3-2 (Inverter module)
2-3-3 Static switch
(1) Uses SCR components as switching circuit between INV and BYPASS. These are controlled
using high frequency electrical technique.
(2) Use high frequency technique to isolate the trigger circuit to prevent false triggering of the
SCR.
(3) DSP control keeps it energized and provides switching signal to connect either bypass or
inverter output to the load.
(4) Assembly model diagram is shown in fig. 2-3-1.
(5) Notice: static switch module and inverter module are mounted in the same heat sink.
EPO
2-3-4 Input start up/protect trigger
(1) Start up function. This function is used for delaying the input power during start up or utility
recovery to protect the unit from electrical surge impact. The function is controlled by the main
control board.
(2) Protection function. This function is used whenever input voltage is too high or too low or
wrong phase sequence or if one phase is missing. In this case, the input trigger will be cut to
protect the unit. This function is controlled and detected by main control board.
2-3-5 EPO switch (Emergency Power Off)
(1) EPO (Emergency Power Off) is a device for shutting down the UPS in case of emergency. By
pressing the EPO button, the UPS can be shut down immediately. When the UPS has been shut
down, all system will be locked and all status are stop. If you want to restart the system, press
“OFF” button on the front panel and then press “Enter” , then press “ON” button and “Enter” to
restart the inverter.

Utility AC input supplies the rectifier /battery charger where the AC is converted into DC. Battery is
recharged while the DC is fed to the inverter module. The static switch module connects the inverter
output to the load while the bypass electricity is blocked. At this time power is supplied by inverter.

In the absence of the utility input, the rectifier stops and DC power is supplied by the batteries to the
inverter module. The inverter converts the DC into AC. The static switch connects the inverter
output to the load. At this time, the inverter supplies the load. When power is supplied by the batteries,
the back up time depends on number of batteries and load level.

Status indication on LCD/LED panel is divided into 4 modes:
(1) System Normal mode: In this mode, only INPUT, RECTIFIER, CHARGE, INVERTER, OUTPUT
LEDs are illuminated and others LEDs are off.
(2) System Bypass mode: INPUT, BYPASS and OUTPUT LEDs are illuminated and others are off.
(3) Back-up mode: DISCHARGE, INVERTER and OUTPUT LEDs are illuminated and others are off.
(4) Manual Bypass mode: When Switch S6 is switched to “ON” position, Only MANUAL BYPASS
LED is on, others are off. It means that the system has transferred to Manual Bypass mode correctly.
After S1, S2, S3 and S4 are switched “OFF”, use a discharging tool to release the remaining voltage
on the DC capacitor. When the MANUAL BYPASS LED is extinguished, proceed to execute
maintenance operation.
