CSI SECTION 16611 STATIC UNINTERRUPTIBLE SYSTEM

1) >130% for 4 seconds

2) 105% continuous

3) <130% Continuous at N+1

b. Bypass Operation:

1) 100A continuous

8. System AC-AC Efficiency: >90% at 100% load

10. Output Power Factor Rating: The UPS output shall be .8 lagging

2.3 ENVIRONMENTAL

A. Storage Ambient Temperature: 5°F to 113°F (-15°C to 45°C).

B. Operating Ambient Temperature: +32°F to 104°F (0°C to 40°C). (77°F is ideal for

most battery types).

C. Relative Humidity: 0 to 95% Non-condensing

E. Altitude: Maximum installation with no derating of the UPS output shall be 10,000 feet

(3000m) above sea level.

2.4 INPUT POWER CONVERTER

A. The input power converters of the system are housed within the parallel connected,

removable power modules, and shall constantly control the power imported from the

mains input of the system, to provide the necessary UPS power for precise regulation of

the DC bus voltage, battery charging, and Main Inverter regulated output power.

B. Input Current Total Harmonic Distortion: The input current THD

shall be held to 6%

or less at full system, while providing conditioned power to the critical load bus, and

charging the batteries under steady-state operating conditions. This shall be true while

supporting loads of both a linear or non-linear type. This shall be accomplished with no

additional filters, magnetic devices, or other components.

E. Input Current Limit:

1. The input converter shall control and limit the input current draw from utility to

150% of the UPS output. During conditions where input current limit is active,

the UPS shall be able to support 100% load, charge batteries at 10% of the UPS

output rating, and provide voltage regulation with mains deviation of up to +/-

20% of the nominal input voltage.
