ORDERING INFORMATION
• Code number: WJF-[1][2][3]-[4][5]
Specify a code from below for each of [1] through [5].
(e.g. WJF-6AA-B/3/Q)
• Special output ranges (For codes Z & 0)
• Parameters
Same range availability as Output 1
Use Ordering Information Sheet (No. ESU-1980) to specify
parameters. Default setting will be used if not otherwise
specified.
(K0
= 1, K
1
= 1, K
2
= 1, A
0
= 0 %, A
1
= 0 %, A = 0 %)
2
• Specify the specification for option code /Q
(e.g. /C01/S01)
Note: When the user requires a current and a voltage
output, specify the current to be the Output 1 which allows
a greater load.
