Current Share Boards - Optional Feature (Cont.)

Specifications:
1.

Power: 2-50 Vdc at 5 mA maximum.

Accuracy: +/- 1 mV between -Vout connections.

Output current when not trimming up: +/- 1 uA (VI-200/J00), +/-5 uA (Maxi).

Use 4 non-plated through holes with standoffs for mounting.

CSB01 MUST be used for current sharing VI-200/VI-J00 converters.

CSB02 MUST be used for current sharing Maxi converters .

Please note:

The CSB is NOT intended for Hotswap Applications

Contact your Regional Applications Engineer at 1-800-927-9474 for additional information.
