ORDERING INFORMATION  
• Code number: WJFK-[1][2][3]-[4][5]  
Specify a code from below for each of [1] through [5].  
(e.g. WJFK-6AA-B/2/Q)  
• Special output ranges (For codes Z & 0)  
• Parameters  
Use Ordering Information Sheet (No. ESU-1681) to specify  
parameters. Default setting will be used if not otherwise  
specified.  
Same range availability as Output 1  
(K0  
= 1, K  
1
= 1, K

= 1, K  
3
= 1, A  
0
= 0 %, A

= 0 %)  
• 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.
