MGE UPS Systems 3.5 to 21 kVA N+1 Manuale Utente

Efficiency

85% minimum, 88% typical (on-line mode); 97% typical (off-line mode) at full kVA/Watt load.

Power Factor

Rated kVA is available over a power factor range of 0.6 lagging to 0.6 leading at nominal volt-

age. Watt rating should not be exceeded.

Total Harmonic

Distortion

Less than 1% for linear load conditions, 3% maximum for crest factor loads up to 3:1.

Line Regulation

System output voltage variation, less than 1% over the DC voltage range.

Load Regulation

System output voltage variation, less than 1% from zero to full load at nominal DC input.

Output Frequency

User-selectable, 50Hz or 60Hz. Free run frequency stability shall be within +/-0.02% of the

selected frequency.

Short Circuit Current

(SCC)300% minimum of rated load current for four cycles. A SCC is defined as a current that

exceeds 150% of rated current.

Overload Capability

Continuous overload up to 108% of rated VA/watts at 50°C maximum.

Transient Deviation

and Recovery

Within 20% of average value for any change in output current or step change in input
voltage within specified limits. Recovery within 1 millisecond from zero to full load.

EMI Emission

Battery Bus less than 30dBrnc. FCC 47 CFR part 15 class A; EN 55022 class A;

CISPR 22 class A
