● Uninterruptible transfer: 0 ms
● Interruptible transfer: ≤ 20 ms
Voltage imbalance: ±3%; phase imbalance: 120±2°
Inverter overload capability:
● 100% < load ≤ 110%: transfers to bypass mode
after 60 minutes
● 110% < load ≤ 125%: transfers to bypass mode
after 10 minutes (tolerance ± 0.1 minutes)
● 125% < load ≤ 150%: transfers to bypass mode
after 1 minute
● Load > 150% or a short circuit occurs: run for 200
ms
Bypass overload capability:
● 30°C environment: works for a long term at 135%
load.
● 40°C environment: works for a long term at 125%
load.
● If the bypass single-phase or three-phase is 150%–
200% overloaded, the bypass can keep working for
5 minutes.
● If the bypass single-phase or three-phase is more
than 200% overloaded, the bypass can keep
working for 1 minute.
● If the load exceeds 1000%, the bypass can keep
working for 100 ms.
● 40 A circuit breaker: 0.75
● 63 A circuit breaker: 0.7
