Fully automate your functional testing with 60V programmable load
Published on 22nd September 2017
Many functional tests require real loads for high fidelity testing, but often tests are performed on static loads that do not get close to representing the dynamic loading seen in real applications.
These static loads are usually bulky, require you to call-off the hardware from the manufacturing system and can work out to be very expensive – especially if the system is at prototype level.
An ideal solution to this would be a flexible, portable system with multiple isolated channels and the ability to be programmed in MATLAB Simulink®.
We’ve recently developed a new 60V programmable load card range, allowing the above requirements to be met within a single unit.
The range builds upon the functionality of our 30V programmable load card, with improved performance and increased capability.
It can be programmed in Simulink®, run Simulink models, and is provided with its own Simulink TSP (Target Support Package)
Programmable load cards provide test engineers with sufficiently high dynamic load simulation to reduce the need for on-vehicle or real load tests, while also being able to provide more repeatable and predictable results.
By virtue of being programmable, tests such as load regulation, battery discharge and curve measurement can be fully automated. The load changes for these tests can be made without introducing switching transients, which might otherwise change the measurement or operation of the power source under test.
Key features of the 60V programmable load include:
- Up to 60V capability
- 8 isolated channels
- Flexible control via:
- Analogue HIL inputs
- Simulink® TSP
These programmable isolated load boards provide 8 channels of independently controllable loads designed for high current applications such as functional simulation of real loads, or low-to-medium voltage battery testing systems.
Each channel provides an isolated independently controlled output stage designed for current control in the 0.1 to 30A range.
The programmable load card controls the current in a closed-loop mode for each channel, with the setpoint being driven from the Simulink model, the hardware-in-the-loop I/O lines or from the CAN interface.
Programmable load cards can slot directly into Genix HIL racks or sub-racks within third-party HIL systems.
