TīmeklisUPS present a different safety issue than most electrical equipment because removing input power from the UPS puts it into backup mode. Removing the input power from the UPS does not remove the electrical charge. To ensure that the UPS is off, turn the inverter OFF before removing the input power from the UPS.

Tīmeklis7.2.2.3 PWM control. Pulse width modulation (PWM) is a modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. The output switching transistor is on more of the time for a high-amplitude signal and off more of the time for a low-amplitude signal.
