Introduction
Does not exceed 3% for all linear and non-linear (computer)
load conditions within the VA/Watt rating.
Inverter output RMS voltage will vary 1% maximum for line
variations between low line and high line at any load between
no load to rated load.
Inverter output RMS voltage will vary 1% maximum for load
variations between no load and full load at nominal line.
2 kVA/1680 Watts, 1 kVA/840 Watts, and .5 kVA/420 Watts
maximum rating available over power factor range of 0.6
leading to 0.6 lagging over rated DC input voltage range.
Crest factor up to 3:1 for non-linear loads within rated
VA/Watt ratings.
50 or 60 Hz, user selectable (see Figure 1-3). When option
-94, Static Transfer Switch is installed and utility AC is
present, the output frequency will be phase locked to within
+/- 6 degrees of the utility frequency. Frequency slew rate
shall be less than one Hz per second. When 60 Hz is
selected, the input frequency must be between 57 to 63 Hz
or when 50 Hz is selected, the input frequency must be
between 47 to 53 Hz or a BYPASS error will be displayed.
Free run frequency stability shall be within +/- 0.02% of the
selected frequency (50Hz or 60Hz).
300% minimum of rated load current for four to five cycles.
Short circuit defined as loads greater than 220% of rated
current.
Continuous overload up to 125% of rated VA/watts at 40º
celsius maximum (120% of rated VA/watts for 2 kVA).
Moderate overload of 125% (120% for 2 kVA) to 150%, 1800
cycles (30 seconds at 60Hz). Severe overload of 150% to
220%, 24 cycles (0.4 seconds at 60Hz).
For a 0 to 100% linear load step change, inverter output
voltage will deviate no more than 20% of rated value, and
shall recover within 1ms.
