MODEL: AB2–[1][2]–[3][4]

ORDERING INFORMATION

• Code number: AB2-[1][2]-[3][4]

Specify a code from below for each of [1] through [4].

(e.g. AB2-1A-B/Q)

• Special input and output ranges (For codes Z & 0)

• Specify the specification for option code /Q

(e.g. /C01/S01)

Use Ordering Information Sheet (NO. ESU-2635) when

presetting of the upper/lower output limit or the ramp rate

range for MAN mode is necessary.

Factory standard setting will be used if not otherwise

specified.

Factory standard settings are as follows.

Lower output limit: -15.0%

Upper output limit: 115.0%

* Minimum response time < Maximum response time
