3.1 Transient voltage Surge Suppression (TvSS) and EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio
frequency interference (RFI). They minimize any surges or interference present in the utility line and keep the
sensitive equipment protected.
3.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC power to regulated DC
power for use by the inverter while ensuring that the wave shape of the input current used by the UPS is near
ideal. Extracting this sinewave input current achieves two objectives:
• The utility power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being protected by
the S4K6U10000.
3.3 Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit and inverts it into
precise, regulated sinewave AC power. Upon a utility power failure, the inverter receives energy from the battery
through the DC to DC converter. In both modes of operation, the UPS inverter is on-line and continuously
generating clean, precise, regulated AC output power.
3.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to continuously float charge the
batteries. The batteries are being charged whenever the S4K6U10000 is plugged in, even when the UPS is not
turned on.
