| Emergency diesel power generator set |
 Single unit power capacity exceeding 2,000KVA with the general system meeting Tier4 standard |
| N+1 backups of diesel generator set |
| Equipped with oil tanks of sufficient capacity including underground oil tank outdoors daily oil tank at power generator room and all oil pump facilities including oil pump and oil pipe etc |
|
| UPS |
| (3+1) backup in the 1st phase to be expanded to 2（3＋1）in the latter phase |
| UPS main frame and batteries are physically separated |
| MGE Galaxy 6000 series supply clean and stable power |
| Duel-conversion operating pattern supplies clean output waveform |
| 12 pulse + active power filter with THDI controlled within 3% |
|
 |
|
| Power supply and distribution system |
| Full redundancy power supply system can completely meet Tier4 standard |
| Complete set of Suhneider framework low-voltage switch system |
| GE 4000A PC-level with bypass ATS |
|

 |
The above power supply system is located on the two sides of the power area on the 1st floor with solid wall standing in the middle for separation. In this way, even if one side of the floor explodes or is destroyed, the power supply system on the other side is still capable of providing the hosting room with power not lower than Tier3 standard.
In one word, SDS’s IDX hosting room has, in a real sense, realized redundancy backup for every part of power supply system.

Measures for Emergency Power Cutoff |
| The other transformer station starts to work if one transformer station goes wrong |
| |
After the two-circuit utility power is cut off and before the emergency power generator starts to work, UPS is capable of full-load operation for 30minutes(normally, UPS does not conduct full-load operation; so, in case of emergency, UPS is capable of supporting about 1hour power supply)
|
| The alternate diesel power generator set is automatically started for power supply (with parallel operating system and load management system) |
| |
It takes less than 15seconds from the generator set receives the order to support the rated load; and the total capacity of oil tanks is capable of supporting the full-load operation of power generator for not less than 48hours |
| When the oil tank reserve of diesel generator goes lower than the alarm line, it will be shuttled to the nearest oil station for more oil; when at the pre-set alarm line, shuttle will be used to add more oil |
| Notes: we enjoy the high authority of oil station; roundtrip is about 15minutes. |
