Diference between "Voltage" & "Sensibility"

[Anonymous user]

I'm dealing with some BR1500G and need to know the main diference between sensibility and voltaje regulation on the PowerChute application, I notice when the sensibility is changed manually the voltaje values changes, so is this relative or totally diferent?

Hello Zaul,

We normally change the sensitivity of our UPS's if the frequency being fed into the UPS is too distorted, this is also sometimes called Total Harmonic Distortion (THD) or dirty power. We lover down the sensitivity settings so that we can minimize the number of times the UPS transfers from online to on battery as this affects the life of the battery.

With regards to the voltage regulation, the UPS looks on the voltage being fed to itself. Depending on the UPS, it can either trim or boost the voltage so not to harm the equipment connected to the UPS. If you're utility voltage is too low or too high and the UPS is always trimming/boosting the voltage it can help minimize the UPS from using the AVR. Too much exposure to AVR might end up on a faulty part.

In some cases, whenever you adjust the sensivity it affects the voltage that it can trim or boost.
