3. Output frequency: 50/60 +/- 3Hz tracking or 50/60 +/- 0.1Hz tracking (user
selectable);
4. AC output voltage distortion: Max. 2% @ 100% linear load; Max. 5% @ 100%
non-linear Load;
5. AC output static voltage regulation: +/-1%;
6. AC output dynamic voltage regulation: +/- 8% maximum for 100% load step at
less than 10ms recovery time;
7. Overload Rating:
a. Online: 105% - infinite; 125% - 1 minute; 150% - 30 seconds;
b. In bypass: Overload is limited by the UPS input circuit breaker which is
rated 16A for 3000VA model, 32A for 5000VA and 6000VA models;
8. Output Power Factor Rating: 0.2 –1.0 lagging, nominal: 0.7 lagging.
2.3 ENVIRONMENTAL
1. Storage Ambient Temperature: -4°F to 140°F (-20°C to 60°C).
2. Operating Ambient Temperature: +32°F to 104°F (0°C to 40°C). (77°F (25°C)
is ideal for most battery types).
3. Relative Humidity: 0 to 95% non-condensing
4. Storage altitude: 50,000 feet (15000m) above sea level
5. Operating altitude: 10,000 feet (3000m) above sea level. At altitude of 10, 000
feet the UPS must be loaded up to 90% of its nominal capacity only.
6. Audible noise: less than 55dBA at 3 feet (1 m).
2.4 INPUT PFC POWER STAGE
A. The input PFC power stage of the UPS constantly rectifies the power imported from the
mains input of the system, converting input mains AC power to DC power for precise
regulation of the DC bus voltage, battery charging, and output power stage (inverter)
regulated output power.
B. Input Current Total Harmonic Distortion: The input current THDI 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.
