Description
HIGH INTELLIGENCE AND RELIABLE POWER SUPPLYIGBT Technology
Full microprocessor control with no-break static and manual bypasses.
Online double conversion technology (VFl) with isolation transformer on theinverter output.
Extremely high short-circuit current to ensure compatibility with the most diffificult transformer applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output.
Compatibled with Watch & Save 3000 software as standard and can be remotely monitored using the Power NetGuard system from anywhere in the world.
SIMPLE TO INSTALL
Capability to install the UPS into any distribution system(neutral not required on rectifier input).
Capability to separate the rectifier/bypass power networks and to power them from two separate sources, without Galvanic isolation(Necessary on UPS without an output transformer
MAXIMUM BATTERY CARE
Battery deep discharge protection;
Temperature compensating charger;
Built-in automatic and manual battery test feature.
OTHER CHARACTERISTICS
0.8/0.9 power factor suitable for powering ICT and lndustrial loads.
BACK FEED protection: to avoid energy feeding back into the mains supply cause a fault occur.
MAXIMUM RELIABILITY AND AVAILABILITY
Connect up to 6 units in parallel or N+1 redundancy, even of different power ratings.
The UPS continue to work in parallel even if one of theinterconnecting communication cables is disconnected(CLOSED LOOP)
LOW CONSUMPTION LEVELS
LF31 Series UPS can achieve efficiencies >98% thanks to selectable Economy Mode which can be used in stable electrical environments to provide power supply continuity when the mains fail.
