9.- OPERATION: SINGLE UPS
This is a True On Line Double Conversion UPS and it is designed to offer clean, bump-less and highest quality power to your
computer related equipments protecting also your valuable data. Power delivered by UPS is 100% sine wave as main line.
According to AC Line status the UPS may operate in following modes:
ONLINE NORMAL Mode
When UPS is turned off by selecting ON push button in front panel and AC Line is normal it enters into ONLINE NORMAL
mode. Under this mode UPS Inverter powers outputs and the energy is taken from DC voltage coming from AC/DC converter.
Batteries are charged by AC Line if required.
BATTERY Mode (Also known Inverter Mode)
Under ONLINE NORMAL mode when UPS detects a problem in AC input Line or black out it enters in battery mode. Under this
mode UPS takes energy from its batteries to power outputs. There are no transfers neither micro-cuts on UPS outputs as
inverter was already working, the only difference is that energy for outputs is now coming from batteries. Transfer time is
actually Zero (0 ms).
UPS also can enter in battery mode when it is turned on without an acceptable AC input.
ECO Mode
There is an energy saving function that makes UPS to power its outputs with AC Line directly. If under this mode, UPS detects
AC input is out of acceptable range it enters into Normal Online mode.
If an AC failure occurs under ECO mode the UPS’s inverter starts working draining energy from batteries. There is a transfer
time of 4 ms typical. This mode is configured and activated from LCD panel. There is specific input voltage range and input
frequency range to configure for ECO mode.
BY PASS Mode
Under BYPASS mode, UPS outputs are powered by AC Line. UPS is out of the circuit. This mode can be caused by operator
by means of the maintenance switch (on the rear panel) or from LCD panel when OFF button is activated, but it may also
happen automatically by UPS malfunction or overload detected at UPS outputs.
FREQUENCY CONVERSION Function
This UPS offers a very sophisticated function named frequency conversion (CF) that allows UPS to generate power output at
determined frequency value (50Hz or 60Hz) no matter input frequency value. UPs will be able to generate output at 50Hz even
input source is at 60Hz or generate 60Hz even if connected to 50Hz source.
This function can be configured and activated by LCD. Revise configuration section of this manual.
IMPORTANT NOTES:
1.- Under CF mode, UPS will disable BYPASS mode. Since UPS has been configured to generate output with frequency value
different to input frequency, BYPASS mode is disable to avoid a not acceptable frequency value at output.
2.- When CF function is activated, maximum power output is de-rated to 60% of maximum nominal capacity. For example, for
a 10KVA (8KW) model, when CF is activated maximum output is decreased to 6KVA (4.8KW).
