How does the device handle synchronous switching?

It automatically searches for the zero crossing point to effectively restrain over voltage and inrush phenomena, especially suitable for switching capacitors and transformers.

What are the lead times for orders?

During peak season, the lead time is one month; during off-season, it is within 15 working days.

What payment terms are accepted?

The accepted term of payment is T/T.
