The AC OUTPUT is created by an inverter that draws power from the mid-bus. This inverter provides
high frequency safety isolation and a pure-sinusoidal output voltage waveform. An optional
electronic breaker can be added to the AC output. This one pole hot side only electronic breaker
allows for fault tolerant, glitch free operation when several UPS units are placed in parallel.
Optional DC outputs at various voltage and power levels are available. The DC1 option is limited
to 500 W. The DC2 option can deliver up to 1250 W output. When the DC2 option is selected, DC
Input is not available. The DC1 and DC2 outputs are isolated from each other and the AC output.
Bulk energy storage capacitors are connected to the mid-bus to help smooth imbalances in
power flow between the inputs and outputs of the UPS.
There is a battery charger circuit that draws power from the mid-bus. It ensures the batteries are
normally fully charged and that the various cells are equalized. The battery also contains protection
circuitry to avoid damage due to improper charging or discharging, or to excessive temperatures.
There is a communication/control port that provides a digital interface to a host computer system.
