| Time delay output | Voltage stabilization output first (protect equipment from impact) | |
| Over-voltage |
When output phase voltage is beyond 10% (245), it cuts off the output, or turns to bypass uninterruptedly |
|
| Under-voltage |
When output phase voltage is lower than 10% (198), it cuts off the output, or turns to bypass uninterruptedly |
|
