Sorry Bob, I was responding to Bob Scott who said it is "Not a surge Protector". 

What he said is " It is a UPS".  You can buy a surge protector for about $25 in Home Depot, and that is all it does is prodtect from power surges.  UPS, also contains a surge protector as an add on, but that is not it's main purpose, which is to provide power in case of a power failure.

Actually, no--a UPS is a line power protection device that very rapidly switches its protected load to a backup power source when it sees the voltage or frequency of the AC line power going outside set limits.  A "power surge" is a high voltage excursion that deviates excessively from the nominal line voltage--a UPS will switch away from line power to it's standby source (battery+inverter) for high voltage power surges and also for low voltage excursions and line frequency excursions that aren't power surges per se.  Some UPS units also have "buck" circuits that can correct a moderately high or low out-of-limit input voltage back to within limits.

A straight surge protector (usually seen in a power strip) uses a voltage-sensitive arresting device like a varistor that shunts the input to ground (in other words short-circuits) to force-trip a fuse or circuit breaker when the input voltage goes out of limits.  When a simple surge protector trips, it interrupts power to the protected device(s).  The overvoltage required to trip a semiconductor surge arrestor is generally much higher than that required to trip a UPS into standby power.  It is also fairly common for the arresting device to destructively sacrifice itself when it trips due to a large voltage spike.  Many UPSes include a few outlets protected only by a surge arrestor, but the battery-backed outlets on the UPS are also (and better) protected from voltage surges by nearly instantaneously switching away from the line input to battery power when even a fairly mild voltage spike is sensed.  So surge protection is indeed one of the primary functions of a UPS.

An overcurrent fault, on the other hand, is a function of the UPS' own self-protection circuitry, designed to prevent fire and/or damage to itself when the downstream load exceeds the design capacity of the device.  When a UPS trips for overcurrent, it shuts down rather than providing continuous power to the client device(s).

Bob- You obviously know a lot more about this than me. Are you saying even though this implies it is a surge protector, I am not getting surge protection?

Surge protector....is basically a circuit breaker inside of a power strip to protect your house/apartment/business electrical
outlet lines from drawing too much current due to an electrical component shorting out in your computer or electrical
device that's plugged in.  Think of a power/current surge as a paperclip shaped into a horseshoe and you stick it into
the receptacle.   ZAP!  One heck of a surge!

I have my TV, Xfinity X1 box, and TV sound bar plugged into a "Voltage Spike" protector.  Voltage spikes occur when
 the power companies tend to throw their big switches during the day and early evening hours re-routing where the
electricity comes from.  The spikes can be up to 20,000 volts and can damage any electronic device you have 
plugged in.

Just my 2 cents worth!

Good example of a power/current surge:

No--all of the outlets on your UPS are protected from "surges" (voltage spikes).  The battery backed outlets are better protected than the "surge protection only" outlets.

If your UPS is tripping off, it's most likely because it's rated load capacity is too small for your PC when heavily loaded (e.g. running MSFS 2024).
