DEVICE Components/blockspure sinusoidal supply the energy and the Both filters work even if the unit is user can see the estimated battery CHARGER working in bypass by using the software or the The charger includes a temperature LCD which regulates the Operating modes charging process.

7 When the mains BYPASS MODESTART-UP SEQUENCE voltage is within tolerances, the charger In this case, the load is directly fed from When the unit is connected to the provides a nominal recharge current up the AC mains. It can be forced by the mains, it automatically starts to work in to to the batteries. This element is user or activated automatically by the bypass mode and thus powers current-limited; therefore, it can only UPS when detecting an overload or connected loads. To switch to line provide the nominal current, although other internal failure.

8 This is also the mode, the user must press the inverter batteries may demand more current. start-up button. After inverter Typical recharge time for internal disconnection through the On/Off ECO MODE batteries is 4 hours (for 90% recharge).button, the unit returns to bypass mode If this mode is enabled, the unit will whenever the mains is in automatic by-pass when mains INVERTERThis sequence allows the load to be fed The inverter consists of a half-bridge is within tolerances. Otherwise, it whenever which uses high frequency automatically switches to line mode (if switching , as the voltage input window is LINE MODEThe inverter is protected against output wider in line mode) or to battery mode.

9 In use, the input AC is converted to DC, short-circuits and is very high efficiency (up to 97%) is and converted back to a pure sinewave. achieved in this mode of prevents the load from suffering LOGIC CONTROL BASED ON DSPL ogic control provided by a powerful power line problems (including total FREQUENCY CONVERTER MODED igital Signal Processor (DSP) shall loss of input AC power) and corrects The unit operates as a frequency sample the output voltage, the load power , providing 50 or 60 Hz at The inverter is constantly synchronised immediately detecting abnormal output when the input frequency is with the input line, thus allowing load voltage conditions and then operating within 40-70 Hz.
