FUNCTION

DESCRIPTION

DEFAULT

SETTING

Acceptable input voltage

range for Source A

Source A will be power source during this

range. When input voltage of source A is

beyond this range, ATS will automatically

switch to power from Source B.

180V – 258V

Return voltage point for

Source A

When input voltage of Source A is back to

normal, the ATS will switch back to Source

A. (Setting Source A as priority power

source and Source B is powering)

Low point: 190V

High point: 248V

Acceptable input voltage

range for Source B

Source B will be power source during this

range. When input voltage of source B is

beyond this range, ATS will automatically

switch to power from Source A.

180V – 258V

Return voltage point for

When input voltage of Source B is back to

normal, the ATS will switch back to Source

B. (Setting Source B as priority power source

and Source A is powering)

Low point: 190V

High point: 248V

Acceptable input

frequency for Source A

Source A will be power source during this

range. When input frequency of source A is

beyond this range, ATS will automatically

switch to power from Source B.

45Hz – 55Hz

Acceptable input
