MODEL: WEPA-1[1][2][3][4]-[5][6]
ORDERING INFORMATION
• Code number: WEPA-1[1][2][3][4]-[5][6]
Specify a code from below for each of [1] through [6].
(e.g. WEPA-11MA5W-C/Q)
• Special output ranges (For codes Z & 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.
