I am looking for a simple system to detect power outage and disconnect heavy loads from the UPS backup to maximize the longevity of the power backup.
The UPS works on a 24-V battery. The UPS switch over time is <15ms
UPS and main output voltages are 230V
Is there an off the shelf device that I can use to achieve this?
Any circuit diagrams of such a system will be helpful
Thanks in advance.
