This is a True Online Double Conversion UPS and it is designed to offer clean, bump-less and highest quality power to your computer
related equipment protecting also your valuable data. Power delivered by UPS is 100% sine wave as main line.
According to AC main service, and how UPS has been configured, it may operate in following modes:
ONLINE NORMAL Mode
When UPS is off by selecting ON push button in front panel UPS enters into ONLINE NORMAL mode if AC main service is inside
acceptable input range. 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)
If under ONLINE NORMAL mode UPS detects a problem in AC input Line it enters in battery mode. Under this mode UPS takes energy
from batteries to feed inverter that generates power for the output. There are no transfers neither micro-cuts on UPS output as inverter
was already working. The only difference is that energy is now coming from batteries instead of rectifier output. Transfer time is actually
Zero (0ms). UPS also can enter in battery mode when it is turned on without an acceptable AC input.
STATIC BYPASS (INTERNAL BYPASS):
This mode can be adopted if UPS configuration allows BYPASS mode and any of 3 below conditions is present:
Under bypass mode, UPS AC output is feed from UPS AC input. When UPS is in bypass mode, in case AC input is interrupted, output
will be interrupted also and UPS will power off. No battery mode can be adopted from bypass mode.
Bypass mode can be caused by any of below conditions:
1- Bypass mode is adopted, in case ON button has not been activated as soon as UPS detects a valid AC input on its terminals.
(If bypass mode is not enable, UPS will simply lights its LCD. Outputs will keep powered off)
2- Bypass mode is adopted as soon as a problem is detected in its internal circuitries.
3- Bypass mode is also activated in case an external overload is detected in UPS output. It happens when equipment connected
to UPS output requires a power higher than max. power of the UPS
Additionally, this UPS can adopt under operator demand other operation modes as described:
FREQUENCY CONVERSION:
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.
ECO:
Under this mode, UPS powers outputs from the AC input. This is a kind of supervised BYPASS mode. As soon as AC input is out of
acceptable input range for ECO mode (as defined on LCD configuration menus), UPS switch UPS from ECO to ONLINE mode or battery
mode. Online mode is adopted if input range is acceptable for ONLINE mode. Switching from ECO to other mode takes about 4ms
to10ms.
ECO mode must be activated on LCD according to 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 3KVA
(2.7KW) model, when CF is activated maximum output is decreased to 1.8KVA (1.6KW).
LCD SCREEN ACCORDING TO OPERATION MODE: (FOR 230VAC models)
LCD screens for 120V models are similar to screens described in this section for 230V.
