Normal Mode
During Normal mode operation, the S2K unit supplies conditioned,
computer-grade power to the connected equipment: mains power
passes through the TVSS circuitry and the EMI/RFI filters and then
through the Bi-Directional Converter to connected equipment.
When the UPS is in Normal mode, the Mains Indicator illuminates
green.
The S2K unit continuously monitors the batteries to maintain them in
a fully charged state. The battery charger operates whenever AC
power is present, even if the UPS is switched off. By default, the UPS
is set to perform an automatic battery test after it has been operating
continuously for two (2) weeks. The interval at which the UPS will
perform a battery test can be configured via MultiLink.
Buck/Boost Mode
The Automatic Voltage Regulator (AVR) circuitry compensates for
fluctuations in mains power, such as voltage surges and sags. When
the S2K unit detects an abnormality, it raises the undervoltage
(
boost
) or lowers the overvoltage (
buck
) as needed. The AVR operates
automatically and maintains the output voltage to the connected criti-
cal equipment, without utilizing the batteries.
When the UPS is in Buck/Boost mode, the Mains Indicator illumi-
nates amber.
