LED Indicators show current UPS status.
LCD Control Panel (240x120 graphic) displays UPS and power parameters as well as hundreds of useful information in multi-language.
Small dimensions - requires small area for unit operation.
High efficiency (>96% from 20% load) reduces heat dissipation and limits power consumption costs.
ECO-Mode gives possibility of significant cost reducing and in practice stops the heat emission.
Backup-time extension possibility provides exact fitting for required autonomy time.
Very high input power factor reduces the value of current gathering from mains.
Very high output power factor allows load of versatile characteristics to be powered.
Wide input voltage range for normal mode causes, that the batteries are used only if necessary - in fact, only when the input voltage is completely lost.
Wide input frequency range for normal mode gives possibility for seamless operation with different power sources - as mains or the generating set.
Simple maintenance - microprocessor control and 24h/7 operation mode means that the unit doesn't require any user handling.
Automatic startup ensures maintenance-free operating even after the unit was switched-off after long time mains failure.
Advanced Battery Management gives reliability of optimal charging and using batteries, elongates its lifetime and reduces operation costs.
Excellent voltage quality is provided by IGBT inverter and high-frequency SPWM modulation method; the output voltage has always stable parameters, independent of input noises and the load characteristics.
High overload capacity indicates power reliability during transient conditions and high resistance on handling faults.
Advanced software provides full control over the unit and the load.
User configurable settings - nominal voltages, frequencies, preferred operating modes, way of communication much widens range of possibly applications.
Manual Bypass (uninterruptible) enables startup of load with exceptionally heavy start without exposing unit output circuits.
