3.4.5 Output frequency (inverter synchronous): 60 Hz (tracks frequency of static bypass
source).
3.4.6 Output frequency slew rate (inverter synchronized to static bypass): 1 Hz/second
to 10Hz/second (selectable).
3.4.7 Free running output frequency (on battery or asynchronous): 60 Hz +/- 0.05%.
3.4.8 Output voltage harmonic distortion:
a. Typically 2% THD with 100% linear load.
b. Typically 5% THD with 100% non-linear load.
3.4.9 Load power factor range: 0.7 lagging to 1.0 within kW rating of UPS.
3.4.10 Output overload capability:
105% to 125% for 10 min. (voltage regulation maintained).
126% to 150% for 1 min. (voltage regulation maintained).
3.4.11 Output fault clearing: typically 1000% for 1 cycle (utilizing bypass source).
3.4.12 The inverter shall have an output contactor to isolate the inverter from the load and
bypass source.
3.5 Environment
The UPS shall be capable of withstanding any combination of the following external
environment conditions without mechanical damage, electrical failure or degradation of
operating characteristics.
