But it is also important to avoid connecting the ups to a power strip to avoid a power spike that can destroy the devices connected to it.
Active pfc power supply ups compatibility.
As a result when a computer system using a power supply with active pfc is attached to a non sine wave ups the system may shut down when it switches to battery power.
600w x 1 25 multiplying.
An energy star 4 0 compliant power supply has to be more than 80 efficient.

Your computer uses a power supply that utilizes active power factor correction active pfc to improve efficiency.

This can be calculated by taking the pfc power supply s rated output power and multiplying it by 1 25 as follows.
Ups compatibility with active pfc smps there are mainly two types of ups based on the output waveform they produce.
Power supplies with active pfc may experience incompatibility problems with a ups that does not provide pure sine wave power output when the power supply switches from ac power to ups battery power.
Pure sine wave ups produces current equivalent to the ones that comes in your homes from the power stations.
For example if a attached power supply is delivering 600w output power its input power can be as high as 750w.
Active pfc compatibility a feature of ups systems that delivers sine wave output to prevent unexpected shutdowns or component stress for connected devices with active pfc power supplies.
The pfc power supply should be connected to an uninterruptible power supply ups to ensure the devices have suitable power in case the main power source goes out.
Power supplies with active pfc may experience incompatibility problems with a ups that does not provide pure sine wave power output when the power supply switches from ac power to ups battery power.
This input power should be the basis for sizing the ups so as not to overload the ups.
First one is the pure sine wave ups and the second one is modified sine wave or square wave or quasi square wave ups.
