Condition: For parts or not working

A Chroma 63103 DC Electronic Load Module offered for parts or repair. The module is missing its dial and is sold as-is with no returns. It is designed for use in the Chroma 6310/6310A series mainframe (6312/6314) for power supply and DC source test applications.

Included in the sale:
• Chroma 63103 DC Electronic Load Module

The Chroma 63103 is a programmable DC electronic load module from the 6310 series, developed and manufactured by Chroma ATE Inc. It is designed for the test and evaluation of multi-output AC/DC power supplies, DC/DC converters, battery chargers, and power electronic components, with applications spanning research and development, production testing, and incoming inspection.

The module plugs into the Chroma 6312 (2-slot) or 6314 (4-slot) mainframe. Each load module uses parallel-connected power MOSFET devices for high-accuracy load control with minimum current drift. FET technology enables the load to sink high current even at very low input voltages — the 63103 is capable of sinking 60A at 1V, making it well suited for testing low-voltage power supplies. Low voltage operation down to zero volts is possible at reduced current levels. A photocoupler provides isolation between output and control sections, ensuring a true floating load.
