5. OPERATION
This is UPS is ONLINE DOUBLE CONVERSION type and it has been designed to offer the most clear power
without switching transitions or dead times. In that way your hardware but also your valuable data will be safe when
your PC related equipment is connected to OPTIMA series UPS.
Power output is sine-wave type same as supplied by AC main source.
Depending of AC input source, this UPS can work under one of two following modes:
Normal AC Mode: It is the default mode when AC input source is OK. Under this mode power output is generated
by UPS inverter. Inverter takes power from AC/DC converter feed by AC input source. AC input source is only used
under this mode to recharging batteries when necessary.
Battery Mode: Also known as Inverter Mode. It is the mode when AC input source is out of range or black-out is
detected by the UPS. Under this mode power output is generated by UPS inverter that takes power from batteries.
There is no dead time (transition time is ZERO ms) related to switching from normal mode to battery mode since
load is always powered from inverter. This is main characteristic of an ONLINE UPS.
ECO Mode: This UPS also offer a third operation mode name ECO MODE. Under this mode (selectable by LCD
configuration menu) UPS works as OFF-LINE UPS. Load is powered from AC input and UPS only switch to battery
mode when input is out of range or in black-out status. Transition time from ECO mode to Battery mode is not zero.
Typically is about 4ms that is why ECO Mode is not recommended for critical applications.
