Specifications
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.
● The UPS runs continuously at 125% load at 40°C;
generates only alarms and uses overtemperature
protection at 125–150% load.
● The UPS runs for 5 minutes at bypass single-phase
or three-phase load 150%–200% at 40°C; runs for 1
minute at bypass single-phase or three-phase load
greater than 200% at 40°C.
● The UPS runs for 100 ms when the load is greater
than 1000%.
