Industrial UPS 120KVA Low Frequency Ups 3 Phase Online UPS 380v/400v/415V

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 these from two separate sources, without Galvanic isolation (Necessary on UPS without an output transformer).

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.

Other characteristics
0.8 power factor make ZGD330 suitable for powering ICT and Industrial loads;
High level diagnostics: event log with 128 messages, states, measurements and alarms - available from the built-in LCD with several languages;

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).
