Maximum battery care:
Battery deep discharge protection;
Temperature compensating charger;
Built-in automatic and manual battery test feature.

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.
