ORDERING INFORMATION
• Code number: KWSBS-[1][2][3]-[4]
Specify a code from below for each [1] through [4].
(e.g. KWSBS-6A6-B)
• Special input and output ranges (For codes Z & 0)
• Parameters (e.g. K1 = 2.00, K2 = 0.10)
When the user requires a current and a voltage output,
specify the current to be the Output 1 which allows a
greater load.
