● 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
● 110% < load ≤ 125%: transfers to bypass mode
● 125% < load ≤ 150%: transfers to bypass mode
● Load > 150% or a short circuit occurs: run for 200
Bypass overload capability:
● 30°C environment: works for a long term at 135%
● 40°C environment: works for a long term at 125%
● If the bypass single-phase or three-phase is 150%–
● If the bypass single-phase or three-phase is more
● If the load exceeds 1000%, the bypass can keep
