OVERVIEW AND FEATURES
The SP-AVR series inverters are advanced and user-friendly power supply units designed to
provide pure sine-wave uninterruptible power to your connected equipment; besides the
big charger capable of charging batteries with up to 35A current (depending on model), the
inverter unlike the traditional ones, also provides a very short transference when blackouts
happen; thus, you may apply it as a UPS, too.
Further, it is also made with Wide Range AVR, offering an output as narrow as ±10% from
the nominal power, while the input power range can vary as large as 140V ~ 310V in the
rated 230V areas; or 70V ~ 155V in the 110V areas. With the wide AVR, you won't need to
use the valuable battery energy during over- and under-voltages. The SP-AVR series
provide the efficiency of over 97% under normal power conditions, and of 86% when
working in the inverter mode. Two charge modes, quick and trickle charge, are applied in
the charger, so as to maintain the batteries in the best condition.
With outstanding performance and reliability, the unique benefits of the inverter include
the following:
Pure sine wave output.
Microprocessor based design with true Line-Interactive structure, DC/AC Isolation.
Remaining Estimated On-Battery Backup Time indication (EBT system on LCD version).
Wide input range 140V~310V for 230V areas; and 70V~155V for 110V areas.
Adjustable charging voltage & voltage-transfer points.
Smart battery management with intelligent double stage charging control.
Adjustable charging current by DIP switch for different types of batteries.
Real time auto-detection of battery condition.
Automatic restart after Inverter shutdown, when the AC power comes back.
Smart AVR function (two buck and two boost modes).
Generator compatible.
Start on Batteries (cold-start) in the absence of AC mains power.
“Green Power” design with auto on/off function and adjustable levels.
Network manageable (optional SNMP support).
Optional RS-232/USB interface for communication, compatible with all major
operating systems, including Microsoft Windows, Linux, SCO UNIX and DOS.
Protection for overload, short circuit and overheat; thermal controlled cooling fan.
Supports solar panel input for charger (Optional)
