VME load card
The VME Load Card is designed to test VME crate power supplies and fan trays by drawing current through the VME backplane and dissipating it as heat.
Specifications
- VME64x compatible card in 6U, single-wide format.
- Front-panel switches to control the current load per voltage channel.
- Up to 10 A load per board on the +5 V and +3.3 V rails.
- Up to 3 A load per board on the +12 V and -12 V rails.
- Different versions available for each VME specification (including VME64x, VME-430, etc.) to test all required voltages.
- LED indicator lights showing current draw.
By monitoring the exhaust-air temperature above a VME load board, it is possible to locate VME slots with cooling issues. Additionally, VME load boards provide an easy method to test the maximum current of a crate’s power supply and to verify that current-trip points behave as expected.
The VME Load Card is a high-precision diagnostic and test module designed to evaluate the performance of VME power supplies and cooling systems under realistic load conditions. By drawing defined current through the VME backplane and dissipating it as heat, the card enables accurate simulation of operating conditions within VME crates. This allows users to test maximum current capabilities, verify current-trip thresholds, and identify slots with insufficient airflow or cooling.
The module features independent front-panel switches to control load current per voltage rail, providing flexible configuration for each test scenario. It supports up to 10 A load on the +5 V and +3.3 V lines, and up to 3 A on the ±12 V rails, making it suitable for a wide range of VME and VME64x applications. LED indicators on the front panel display real-time current draw, allowing direct visual feedback during testing.
Available in multiple variants for different VME standards (VME, VME64x, VME-430, and dedicated +5 V versions), the VME Load Card covers all relevant voltage rails used in modern and legacy systems. Its robust 6U single-slot design ensures compatibility with standard VME crates and backplanes.
With its simple operation, reliable performance, and full mechanical compliance with ANSI/IEEE STD 1014, IEC 821, and IEC 297, the VME Load Card is the ideal tool for verifying crate power integrity, optimizing cooling performance, and ensuring stable, fault-free operation in demanding VME environments.
