High reliability:
Extremely high short-circuit current to ensure compatibility with the most difficult transformer applications (lighting, drives and industrial processes) and an isolation transformer on the inverter output;
Full microprocessor control with no-break static and manual bypasses;
IGBT technology.
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 the interconnecting communication cables is disconnected (CLOOSED LOOP).
Low consumption level:
ZGD330 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.
Advance communication
Compatible with TeleNetGuard for remote maintenance; Advanced, multi-platform communication for all operation systems and network environments: Watch & Save 3000 monitoring and shut-down software included, with SNMP agent, for Windows 2008, Vista,2003, XP; Mac OS X, Linux, Novell and most popular Unix operating systems;
The UPS is supplied with a cable for direct connection to the PC(Plug and Play); RS232 double Serial port; Installation slot for an Emergency Power Off (EPO) interface to allow the UPS to be switched off remotely in an emergency; Generator interface: enables resynchronization of the UPS output from a generator supply which may be subject to phase and frequency variations. The interface also enables more economic use of the battery charge.
