VPX 3U Load Board
The VPX 3U Load Board is a test card designed to simulate resistive loads on VPX systems, enabling comprehensive electrical and thermal testing.
- Configurable resistive load on +12 V and +5 V Standby rails
- Air-cooled with heatsink
- Automatic shutdown at ~120 °C
- Voltage and temperature sensing via front-panel connectors
- Automatic reactivation after cooling
Product Information
It includes automatic thermal protection that powers down the board if temperatures exceed 120 °C and automatically restarts after cooling.
The VPX 3U Load Board provides precise resistive load simulation across multiple voltage rails in a 3U, 5HP form factor. It enables engineers to test power supply capacity and thermal behavior under realistic conditions. The board features automatic over-temperature shutdown and voltage/temperature sensing for detailed system analysis..
