inside them but with a reinforced battery charger. These models are normally used for high backups and they are
accompanied by battery cabinets.
Main characteristics
• Low distortion sinusoidal output voltage: a modern inverter with modulation control of the pulse width
(PWM) generates a sinusoidal output with minimum distortion, allowing power to be supplied to sensitive
apparatus.
• High input power factor and low distortion sinusoidal of input current: the high frequency rectifier
or corrector (PFC) which allows the UPS consumes power with a power
factor near to unity and with a low distortion sinusoidal of input current, no matter what type of connected
load to the equipment.
• Microprocessor control: All the power conversions are controlled by totally digital signal. Excellent
performance and reliability are realized together with all kinds of protection functions.
• Instantaneous transition from normal to battery mode operation and vice versa: as this is a double
conversion model, there is no failure in the output voltage in transitions between mains and battery.
• High input voltage range: The rectifier works at mains of low voltages at full load, which prevents energy
from being extracted from the battery even at these voltages.
• High efficiency: this UPS range has a high efficiency up to 92%.
• Protected against overloads and short-circuits: are fitted with protection circuits that
prevent the device from being damaged by short-circuit or excess load.
• Front control panel: in the front of UPS there are LED indicators, a LCD display and a keypad which
indicate the operation mode, mimic diagram, warning and failure information, and allow browsing through
the display to monitor UPS data and necessary settings.
• Monitoring software: included RS232 and USB type connections which, by means of software, allows
you to save files, run programmes, turn off the PC, etc., as well as monitoring in real-time the status of the
UPS.
• Self-Battery and UPS test: also is included a function that performs a battery and UPS test in order to
check status of them.
• Battery test: this series has an option that performs a battery test in order to check the battery status.
• 3-level intelligent charger: UPS of this series has an intelligent charger of three optimized battery charge
levels to enlarge the lifetime of the batteries.
