2.4 Power Supplies

See section 1.3 for power requirements.

When setting up the camera’s power supplies, follow these guidelines:

•

 

Do not use the shield on a multi-conductor cable for ground.

•

 

Connect separate supplies at  the source and at the camera.

•

 

Use separate leads for better noise immunity.

The companies listed below make power supplies that meet the camera’s
requirements, but they should not be considered the only choices. Many high
quality supplies are available from other vendors. DALSA assumes no
responsibility for the use of these supplies.
