1. Preface
1-1 Introduction
DS-C33 II series features an advanced DSP chip as a system core processor. Wide range capacity from 10KVA
to 200KVA meets a verity of load demands and extends the capacity up to 400KVA through paralleling. High
reliability and rapid transient response fit for critical equipments such as semiconductor, SMT and
communication facilities, etc.
HMI (Human machine interface) touch screen panel provides a user-friendly VIS (visual integrated system)
for real-time monitoring, easy maintenance. Fan operation depending on load condition achieves noise
reduction and energy consumption decrease. DS-C33 II is the best choice for dealing with critical power
needs.
1-2 Safe Instructions and Warnings
For safe operation, warning marks for DS-C33 series are:
DO NOT TOUCH DANGEROUS HIGH VOLTAGE
Dangerous high voltage mark pasted indicates high DC voltage. Do not touch the surface marked with it.
When batteries are being discharged (during blackouts), do not switch off (open circuit) the battery
magnetic switch to avoid danger.
Batteries are consumptive parts. Check if battery voltage, current and appearance are normal every 4
months to make sure the UPS operates normally and safely. If batteries are overheated or deformed,
replace them with new batteries to avoid fire danger because of lead acid liquid leakage.
Without using the UPS or AC mains supply for a long time, remove UPS’s battery fuses, switch off the
battery pack’s breakers or remove batteries in order not to damage batteries.
UPS is power system equipment and it requires grounding. The load of the UPS requires a separate
grounding.

2-2 System Major Module Function Introduction
2-2-1 Rectifier
(1) Utilization of SCRs inverts AC voltage to DC voltage.
(2) Combination of CPLD and DSP make the rectifier more stable and reliable.
(3) Over-voltage protection.
(4) DC voltage soft starter.
(5) Float charging and equalization charging modes support.
(6) Float charging time is adjustable and available on the display panel.
(7) Battery test can be done with continuous AC supply.
(8) Manual and automatic periodic battery tests are settable on the display panel.
(9) Charging current is settable on the display panel.
(10) 12-pulse rectifier is optional for reducing input THD.
2-2-2 Inverter
(1) IGBT as a power component is adopted.
(2) The inverter is equipped with an output isolation transformer.
(3) DSP digital control processing technology is applied to improve analogue components’ aging,
temperature drift and for the purpose of using fewer components.
(4) Integrated A/D signal processing, 12-bit resolution and fast transition are featured.
(5) Heat dissipation structure combined with temperature protection makes the inverter more reliable.
2-2-3 Static Transfer Switch
(1) Use of SCR for the static transfer function of the inverter and the bypass can work in a variety of
environments.
(2) High-frequency technology isolates the trigger circuit. The trigger circuit effectively triggers the STS
and results in switching without disconnection between inverter and bypass loops.
(3) STS has triggering conditions for disable, bypass and inverter loops and is fully controlled by DSP.
2-2-4 Emergency Power Off (EPO)
For emergency or force majeure in operation, EPO is used by pressing the button for shutting down the UPS
immediately. Press EPO button to completely stop the UPS and EPO light is turned on (Fig 2-2-4 Left). Press
EPO button and select the button of “Turn off inverter” on the display panel to restart the UPS and EPO
light is turned off (Fig 2-2-4 Right).
Fig. 2-2-4

2-3 System Operation Modes
2-3-1 Normal Operation
Fig. 2-3-1 Normal Operation
AC mains power goes through the rectifier, the inverter, the STS to the load.
2-3-2 Bypass Operation
Fig. 2-3-2 Bypass Operation
AC mains power goes through the bypass path and the STS to the load.
2-3-3 Battery Supply Operation
Fig. 2-3-3 Battery Supply Operation
The power supplied from batteries goes through the inverter and the STS to the load. When the load
consumes power from the batteries, its backup time depends on the battery capacity and the load power
consumption. Therefore, save your data and turn off the personal computers as soon as possible when a
blackout occurs.

2-3-4 Maintenance Bypass Operation
Fig. 2-3-4 Maintenance Bypass Operation
AC mains power goes through the maintenance bypass switch to the load. This mode is only for trained
professionals to do regular system and cleaning maintenance.
2-3-5 EPO Switch
Fig. 2-3-5 EPO Switch
UPS is going to be turned off and outputs no power in this mode for emergency.
