If all of your components are working correctly, everything is fine, but when a defect occurs, it is important to locate and eliminate the error quickly and efficiently.
With cascaded power supplies, it was until now only possible to conclude that something was amiss from a distance, but the system could not be queried to find out which power supply unit was defective, or whether it was even plugged in, and which power supply address was affected by the defect.
This all changes with the new intelligent Power Backplane from Hartmann Electronics. The integrated and configurable microprocessor takes care of the soft start of each power supply unit, as well as hot-swap operations. The microprocessor independently recognises which power supply unit is down or if a power supply unit is not properly inserted, and reports this to the system over the ACFAIL signal.
All settings and addresses can be easily configured using DIP switches and all signals are easily accessible via plug-in connectors. The Power Backplane's current capacity is 128A.
Although it incorporates active microprocessor switching, the Hartmann Power Backplane can operate over a military temperature range from -40 to +85°C.
