Specifications
System
Three-phase, four-wire, and PE
Voltage
380 V AC/400 V AC/415 V AC (line voltage)
Frequency
In normal mode, the frequency is synchronous with the
bypass input frequency.
In battery mode, the frequency is 50/60 Hz with a tolerance
of ±0.05%.
THDv
THDv ≤ 1% (full linear load)
THDv ≤ 4% (full non-linear load)
Power factor
1
Transfer time
Uninterruptible transfer: 0 ms
Interruptible transfer: ≤ 20 ms
Output voltage imbalance
Voltage imbalance: ±3%; phase imbalance: ±2°
Overload capability
Inverter overload capability:
100% < load ≤ 110%, at 40°C: transfer to bypass mode
after 60 minutes
110% < load ≤ 125%, at 0–30°C: transfer to bypass mode
after 10 minutes; at 30–40°C: transfer to bypass mode after
3 minutes
125% < load ≤ 150%, at 25°C: transfer to bypass mode
after 1 minute; at 40°C: transfer to bypass mode after 30s
Load > 150% or a short circuit occurs: transfer to bypass
mode after 200 ms
Bypass overload capability:
The UPS runs continuously at 135% load at 30°C;
generates only alarms and uses overtemperature protection
at 135–150% load.
