Low Frequency UPS 10-500kVA (3/3 PF:0.8)

Uranus Series Low Frequency Online UPS | Capacity: 10kVA-500kVA | Power Factor: 0.8 | Phase: 3/3 | Input/Output Voltage: 380VAC/400VAC | Frequency: 50Hz/60Hz

Uranus series low frequency online UPS adopts advanced DSP digital control technology and IGBT high-frequency Pulse Width Modulation (PWM) technique, making it a reliable and stable power supply solution. The double-conversion online topology design produces a pure sine wave power supply, which effectively filters out noise, interference from power grid fluctuations, and tracks, phase-locks, and regulates voltage to provide comprehensive protection for users. After more than 10 years of elaborative design by Prostar R&D center, the modular structure of the UPS is 5 times more reliable and stable than regular UPS, with an MTBF of over 300,000 hours.

Uranus series low frequency online UPS is equipped with standard-built output isolation transformers, a static bypass switch, and a manual maintain switch, making it highly capable of engaging in short-circuit and suitable for use in the worst environments. It also has perfect protection functions and combines AC input, over-voltage, under-voltage, output over-voltage, short-circuit protection, inverter, rectifier over-temperature protection, voltage under-voltage warning, battery overcharging protection, and other protections to ensure stable and reliable system operation.

Uranus series low frequency online UPS includes 3-phase ins and 3-phase outs from 10kva-500kva, which can be directly paralleled with 8 units UPS conveniently and quickly using flexible parallel technology for different loads and systems. According to the needs of customers, it can be configured for N+1 or N+X construction, and depending on the different capacity needs of customers, it can be randomly paralleled with 8 units UPS. All the load will be evenly distributed across all 8 units of the parallel redundant UPS system, and in case of any UPS failure in the parallel redundant system, the UPS will immediately share its load to ensure normal system operation. During the parallel UPS process, it does not set the host and the standby unit but allows customers to select them flexibly. The first turned-on UPS is automatically set to the host, and when the host system fails, the host identity is immediately transferred to another UPS, ensuring the supply of electricity for clients during the usage process, making it a true uninterruptible power supply.
