2.2.1 Conceptual Diagram
The UPS5000 is an online UPS with a modular design that facilitates maintenance and
capacity expansion. All modules are under intelligent digital signal processing (DSP) control.
A power module consists of a rectifier and an inverter. The power module converts inputs into
pure, high-quality sine wave outputs by using high-frequency switching. Figure 2-2 shows a
conceptual diagram for the UPS.
