Power frequency UPS uninterruptible power supply

Power frequency UPS uninterruptible power supplySUG 3/3 series,It consists of a thyristor (SCR) rectifier, an IGBT (Insulated Gate Bipolar Transistor) inverter, a bypass, and a boost isolation transformer. As the rectifier and transformer work at a frequency of 50Hz, it is called a power frequency UPS. With an isolation transformer, it has good resistance to load impact and can withstand motor type impact loads and short-circuit current impacts.

Power frequency UPS uninterruptible power supplySUG 3/3 seriesTechnical features:

1. Adopting thyristor rectification technology, the system has high reliability.

2. Output configuration isolation transformer, zero ground voltage increment is zero, more reliable to ensure load operation.

3. The short circuit impedance of the output isolation transformer and its high-frequency attenuation isolation characteristics enable the power frequency equipment to have good resistance to load impact, reducing the impact of load transients and short circuits on UPS.

4. By redistributing the load through transformers, the ability of UPS to handle unbalanced loads has been improved.

5. Even in the event of UPS failure, there is no risk of outputting DC voltage, making the load safer and more reliable.

6. It can implement configuration schemes for different input sources in the main bypass to meet the distribution requirements of high reliability sites.

7. The battery is directly connected to the busbar, and when the load is not fully loaded, the remaining rectifier capacity can be used for charging, which is particularly suitable for the demand of configuring backup batteries with long delays.

8. Adopting high-power module packaging devices, it can withstand motor type impact loads and short-circuit current impacts.

9. Extremely wide input voltage range, no switching time, and stable output voltage with high accuracy, suitable for harsh power grid environments.
