MODEL: WDNY–[1][2]–[3][4]

ORDERING INFORMATION

• Code number: WDNY-[1][2]-[3][4]

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

(e.g. WDNY-A6-B/E/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.
