German BEINING Power System | Reliable Power Support | Safeguarding Critical Equipment Operation
Reliable Power Protection for Critical Equipment
I. Product Overview
The German BEINING ENERTRONIC I series industrial uninterruptible power supply systems are a high-performance product line designed to meet the demands of the world's most challenging industrial environments. This series covers a complete power range from 1kVA to 500kVA, employing a true on-line double-conversion topology and strictly complying with the highest UPS classification VFI-SS-111 as defined in IEC/EN 62040-3 standards.
VFI stands for Voltage and Frequency Independent, meaning that the output voltage and frequency are completely regenerated by the inverter, independent of any disturbances on the input side. Whether the utility experiences voltage sags, voltage swells, harmonic distortion, frequency drift, or complete blackout, the connected load always receives clean, stable, regulated sine wave power.
II. Core Technical Advantages
True On-Line Double Conversion Topology
The ENERTRONIC I series employs a true on-line double conversion operating mode. During normal utility operation, the AC input passes sequentially through the rectifier and inverter stages before powering the load. During a utility failure, DC power from the battery is converted directly to AC by the inverter, with the transition occurring without any interruption. This topology ensures that the output voltage waveform is always actively generated by the inverter, completely unaffected by input power quality.
IGBT Power Semiconductor Technology
Both the rectifier and inverter stages utilize advanced IGBT transistors in conjunction with sinusoidal pulse width modulation control strategies. Compared to traditional thyristor technology, the IGBT solution achieves higher switching frequencies, lower conduction losses, and superior dynamic response characteristics. The combination of 16-bit microprocessors and advanced power electronics technology ensures highly reliable control and monitoring of the rectifier, inverter, and static bypass systems.
High Input Power Factor
Input power factor reaches above 0.99. This specification means that the UPS presents an almost purely resistive load characteristic to the upstream grid, significantly reducing the capacity requirements for front-end equipment such as input cables, transformers, and switchgear, while also reducing electricity costs associated with reactive power.
Low Input Current Harmonic Distortion
Input current total harmonic distortion is below five percent. Extremely low harmonic feedback means that the UPS does not cause harmonic pollution to other equipment on the same power distribution system, meeting the strictest grid harmonic regulations without the need for additional input filters.
III. Output Performance Specifications
Excellent Voltage Regulation Accuracy
Output voltage regulation accuracy under static conditions is better than plus or minus one percent. Even during one hundred percent load step changes, the inverter's dynamic output voltage deviation remains very small with extremely short recovery time.
Pure Output Waveform
Output voltage waveform is pure sine wave, with total harmonic distortion below two percent for linear loads and below five percent for non-linear loads. The system maintains good efficiency and low distortion factor even under partial load conditions.
Strong Overload Capacity
One hundred fifty percent of rated load can be sustained for ten minutes; one hundred twenty percent of rated load can be sustained for ten minutes; bypass overload capacity can reach five hundred percent.
High Short Circuit Current Capability
The ENERTRONIC I series offers excellent short circuit current output capability. Under three-phase configuration, short circuit current can reach three to four times rated current; under single-phase configuration, it can reach six to seven times rated current. This capability ensures that during downstream short circuit faults, the UPS can output sufficient current to reliably trip downstream circuit breakers, enabling selective protection coordination.
IV. Operating Modes
Normal Operating Mode: During normal utility operation, the rectifier converts AC to DC voltage, simultaneously powering the inverter and floating the battery. The inverter converts DC to pure AC to supply the load.
Battery Operating Mode: When utility voltage deviates outside specified limits or fails completely, the battery automatically cuts in to power the inverter without any interruption.
Bypass Operating Mode: When inverter output exceeds preset tolerance ranges or cannot supply power normally due to a fault, the static bypass switch automatically transfers the load to bypass utility power.
Auto Return Function: After a bypass transfer event caused by overload or short circuit is resolved, once the inverter output returns to normal, the system automatically transfers the load back to inverter power.
V. Parallel Operation Capability
Up to eight ENERTRONIC I series units can operate in parallel for redundant configurations or to increase total output power capacity. Parallel systems operate in active master/passive master mode, with load current shared equally among all parallel units, eliminating the single point of failure risk found in traditional master-slave parallel configurations.
VI. Monitoring and Communications
Human-Machine Interface: Equipped with membrane keyboard and LCD display, graphically displaying the current power flow path and system operating mode.
Event Logging: The system event logger can store a large number of events, each with date and time stamp, facilitating fault analysis and system status tracing.
Communication Interfaces: Standard RS232, RS485, and MODBUS RTU protocols are included, with optional Profibus DP, Ethernet, and other interfaces available for seamless integration into various industrial automation systems.
VII. Application Fields
The ENERTRONIC I series is widely used in petrochemical, power systems, rail transit, industrial automation, data centers, nuclear power plants, medical facilities, and other fields, providing reliable power protection for critical loads.
VIII. Quality and Service
All products are manufactured under ISO 9001 quality management system certification and undergo comprehensive functional testing and burn-in testing before leaving the factory. BEINING provides full lifecycle services from product selection, engineering design, installation and commissioning, to after-sales maintenance.
