500kva modular ups power supply high frequency and parallel ups power 25kva intelligent power module

Product Description: 

applying power. With the large touch screen LCD panel, the user can easily access to the information of the power module and the system.

Intelligent Battery Management

Each UPS module builds in with super charger and the power reaches 3200W. With 10 installed UPS modules, the total charging power rating is up to 32KW. The charger is controlled by DSP with intelligent digital arithmetic thus to prolong the life time of the battery.

Intelligent Protection System

All the power modules and the system are protected simultaneously by the hardware and the software. All kinds of protection functions are realized, including current and voltage abnormal, thermal abnormal, short circuit, etc. The reliability of the power module and the system reaches an incredible high level through all of these technologies.

Additional Outstanding Features

u  High input power factor (>0.99), low input THDi (<3%).

u  Strong load adaptability for linear and nonlinear load.

u  Intelligent module and system protection design.

u  Incredible low noise system design.

u  Double DSP controller for individual power module.

u  Digital control for the whole parts including rectifier, inverter, charger and discharger.

High reliability design

Integrated IGBT modules are used in the power module. Comparing to discrete chips, system reliability and manufacturing consistency are much improved. Low-loss integrated three-level IGBT modules help to increase system efficiency. Meanwhile reliability is increased due to lower temperature rising on IGBTs and heatsink. More chips need to be paralleled to realize high current rating if using discrete IGBT chips. Clamped Diodes should be placed around IGBTs which brings risk for voltage/current stress issues and manufacturing process.
