Minimum impact on supplies easy sources:
Input current distortion <4% for the ZGD330 with filter with sinusoidal absorption to remove the risk of resonance with other input supply users or phase shift capacitor sets. The absorbed current distortion is independent of input supply parameters such as impedance. This enable ZGD330 to deliver maximum performance levels regardless of the installation environment. With these input features ZGD330 can achieve significant savings in terms of sizing and power supply sources isolation transformers and generators over less sophisticated power systems.
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.
