I'm designing a system integrating:
- an industrial PC with 230V AC input (~300W)
- various peripherals requiring 24V DC (150W max)
In case of external AC power loss, the DC components (2) need to be supplied with backup power for up to five minutes. This is not a problem and suitable PSU are available.
However, for a reason I cannot control, the industrial PC requires an advance signal (about 1 second in advance, possibly less) indicating that its supply power is about to be lost.
So I'm looking for suitable 230V AC buffer with power loss notification. Compliance with IEC 60601-1 (3rd) would be a big plus.
I don't know exactly what I'm looking for. I would like to avoid a full-blown UPS, even though a battery is needed for the 24V PSU. Could anyone direct me to the right kind of component?
