10. Start-up time

The boot mode can be selected by the monitoring module:

1) Normal power-on mode

The time delay from AC power-up to module output is less than 5 seconds.

2) Output slow start

This function is set by the external monitoring module is effective, the start-up time can be set by the monitoring module, can be set a range of 8s to 128s, accuracy ≤± 10%.
