Input Input Mode Three-phase/four-line input
rated voltage 400 Vac( line to line)
voltage range 1. If the Phase to neutral voltage is in the range of 176-276Vac, the UPS
can work normally with full load;
2. If the phase voltage is in the range of 120-176Vac, the ability of the
UPS to supply the load will decrease linearly with the decreasing of the
input voltage, it can work with half load when the voltage is 120Vac.
3. Working under Phase failure condition:
1）if one Phase failure, the other two phases are normal, the UPS can
supply 50 % rated load at most;
2）if input two phases failure, the other one phase is normal, the UPS can
supply 25 % rated load at most

Output Frequency In normal mode, when the Bypass frequency is in the tracking range
（
50Hz±10%, 6%, 4%, 2% and 1% optional, defailure value is ±
4%）,the inverter Output will track Bypass frequency;when the Bypass
frequency is beyond the limit, the inverter Output frequency is 50Hz±
0.2%;in battery mode, the inverter Output frequency is 50Hz±0.2%

Utility or
Battery）
be able to withstand 105~125% rated load for 10min;then the UPS
transfers to bypass output;
be able to withstand 125~150% rated load for 1min,then the UPS transfers
to bypass output;
When Load Power> 150%,the inverter can work for longer than
200ms,then the UPS transfers to bypass output;
Bypass Overload
Ability If the load current is in the range of 135%-155% rated output current,the
UPS will be disconnected from the load after 15min;
If the load current is more than 155% rated current,the UPS will be
disconnected from the load after 3min（if extreme big current occurs in
3min,the disconnection time is decided by the release time of bypass
breaker）
