DSP fully digital control technology

Pure online dual transformation architecture with strong load capacity

Dual input power distribution method, higher system availability

Three in and three out, supporting 380/400/415Vac, 50/60Hz power grid

Input power factor of over 0.99, low harmonic current, green and environmentally friendly, efficient and energy-saving

Lightweight and efficient, with a maximum load efficiency of up to 96% in online mode

500kVA occupies an area of only 1.02 square meters, with higher power density

Online mode has a maximum efficiency of 96%, while ECO mode has a maximum efficiency of 99%, significantly reducing customer operating costs

Wide input voltage range, 50Hz/60Hz power grid system adaptive, suitable for various environmental power grids

Supports 50Hz input/60Hz output and 60Hz input/50Hz output frequency conversion modes to meet the special needs of users

Adopting a forward and backward airflow heat dissipation method, with a unique air duct heat dissipation design, it quickly dissipates heat and maintains the stable operation of core components

Advanced multi machine parallel technology, high parallel reliability, and low circulating current

Parallel machines can share battery packs, saving users battery investment

Flexible charging parameter settings and battery configuration, with 30-46 batteries to choose from

Advanced battery intelligent management technology (intelligent charge and discharge management and float charge voltage temperature compensation) effectively extends battery life

Advanced charger management technology. The voltage input range of the battery charger is the same as that of the UPS input range. The newly added battery charger can be included in the system management control to achieve automatic management of battery pack charging and discharging, with RS485 standard communication interface to meet remote monitoring and management.

Support battery cold start and mains power self start functions to meet users' usage needs

Modular design, high reliability, and easy maintenance; Support full positive maintenance

Self aging function, convenient for on-site debugging and testing

Low voltage shutdown (EOD) self recovery function of the battery. The system's mains power is abnormal and converted to battery inverter power supply. When the battery shuts down due to low voltage, the entire system output loses power, and the input returns to normal, the system can decide whether to allow the system output based on monitoring settings

Comprehensive software and hardware protection functions, powerful self diagnostic capabilities, and rich historical record queries

7-inch ultra large LCD touch screen display, user-friendly human-machine interface

Telemetry and remote signaling performance: Standard SNMP card, supports RS485 and dry contacts. Equipped with remote signaling and telemetry functions, the accuracy of switch remote signaling reaches 100%; The accuracy of analog telemetry reaches: DC voltage error ≤± 0.5%, and other electrical errors ≤± 2%

The equipment casing frame adopts a combination of cold-rolled sheet and galvanized sheet profiles, which are hard and sturdy, with a protection level of IP20
