Recently, Shenzhen SST Power Co.,Ltd has launched a new rack-mounted UPS that has made a striking entry into the market. This product offers more reliable power protection for the stable operation of critical equipment across various industries, quickly becoming a market focus with its outstanding performance and innovative design, and is expected to reshape the power protection landscape.The rack-mounted UPS adopts an advanced double-conversion online architecture, effectively blocking the impact of abnormal power supplies on loads and ensuring stable, precise, and reliable output power. When confronted with complex power issues such as mains power outages, voltage fluctuations, and frequency instability, it can achieve 0ms switching, providing uninterrupted and high-quality power supply to loads. With an output power factor of up to 1.0, its load-carrying capacity is significantly enhanced, enabling efficient matching with various IT equipment and reducing operational costs.The product features an ultra-wide input voltage range (110Vac - 300Vac), adapting to diverse harsh power grid environments. It operates stably whether in remote areas with unstable voltages or industrial scenarios with strong grid interference. The wide frequency range of 40 - 70Hz not only complies with power grid frequency standards in multiple regions but also efficiently collaborates with generators to ensure continuous and stable power supply. Additionally, the mains recovery delay startup time can be set to flexibly respond to grid fluctuations and reduce the impact on the power grid when equipment starts.In terms of intelligent management, this rack-mounted UPS supports multiple intelligent communication cards, allowing easy integration into existing monitoring and management systems for remote real-time monitoring and operation. Users can check the equipment's operating status and receive fault alarm information at any time via mobile APP or computer terminals, greatly improving operation and maintenance efficiency. Its intelligent charging function employs a three-stage charging mode combined with automatic temperature compensation, effectively extending battery life and increasing charging speed.In terms of size design, the product has a height of less than 2U and a width and depth of less than 500mm. Its compact size enables flexible adaptation to various installation environments with limited space, making it particularly suitable for scenarios with high space utilization requirements such as data centers, enterprise computer rooms, and communication base stations. Moreover, it boasts excellent mute performance, with automatically adjustable fan speed, and its minimum noise meets the first-class mute standard of libraries, offering an ideal choice for noise-sensitive environments.As the digitalization process accelerates, industries have increasingly stringent requirements for power protection. The rack-mounted UPS launched by Shenzhen SST Power Co.,Ltd accurately meets market demands, builds a solid defense for data security and continuous business operation, and is set to play a significant role in the power protection field, driving the industry to new heights.

Electrical equipment that requires stable voltage.

Generally, diesel generators distribute power to UPS systems, due to UPS interference such as harmonic feedback and sudden changes in load current, the ratio given by the design institute is 3:1, which means the capacity of the diesel generator needs to be 3 times the maximum load of the UPS.  But in fact, in GDS, CICC Data, and actual interconnected data centers, the optimal  ratio between diesel generators and UPS is 2 or 1.5:1, which not only reduces the cost but also improves energy utilization.When the UPS is used in conjunction with a generator, only a small amount of backup battery is needed for the UPS to prepare for switching.( Back-up time can be 5 to 15 minutes).  The conversion between the generator and the mains power can be done manually or with an automatic switching device (ATS). When the mains fails, the automatic switching device (ATS) will automatically switch to the generator, and the generator will automatically start after a certain time delay to provide power protection.In practical applications, different customers have different availability requirements for the power supply system, so the configuration methods of UPS and generators are also different. The following are the most common and economical options.As shown in the figure, the diesel generator is used as the backup power supply of the mains. When the mains power fails, since the generator takes a certain time to start and cannot provide instantaneous power, the UPS uses the battery to provide uninterrupted power supply. Shenzhen SST Power UPS is with ZERO Switch Time, it can play a very good role in protecting the user's load equipment. After the generator is running stably, the input of the UPS is switched from the mains to the generator to prevent the system power supply from being interrupted due to battery exhaustion. This solution can effectively solve the problem of instantaneous power outages and long-term power outages and ensure the continuity of equipment work. We have just shipped a 200KVA/160KW low frequency online UPS, equipped with a diesel generator, providing customers with a perfect solution and effectively protecting their load equipment.If you want to know more about UPS performance or supporting solutions, please contact our sales to learn more.

Uninterruptible power supply systems are used to provide backup power during power outages or fluctuations to ensure that hospitals can continue to operate normally in the event of power failures or other electrical problems. Many critical equipment and systems in hospitals, such as operating rooms, ICUs, emergency rooms, laboratories, etc., have high requirements on the reliability of power supply, because power interruptions may have a serious impact on patient safety and medical services. A hospital UPS system usually consists of one or more UPS hosts, batteries and battery cabinet, and power input and output wires connected to the hospital power system. Medical systems, especially equipment such as CT machines and X-ray machines, must be equipped with UPS power supplies.How to choose the right medical ups power supply?1. An online UPS uninterruptible power supply with zero switching time needs to be selected.2. When supplying power to capacitive loads such as computers, its rated output power should be greater than 1.5 times the sum of the rated power of each computer equipment, and when supplying power to other electrical equipment, it should be 1.3 times the maximum calculated load.3. The inrush current of the load shall not exceed 150% of the rated current of the UPS.How to choose the UPS power supply for the hospital-related equipment? The following equipment options are suggested for your reference.1. Color ultrasound, biochemical analyzer, blood cell analyzer, plasma collector, electrolyte analyzer, chemiluminescence immunoassay analyzer, CT and nuclear magnetic resonance workstation and other equipment, basically 3000VA UPS uninterruptible power supply is enough for a single instrument, For some higher power models, 6000VA is enough.2. CT and nuclear magnetic resonance machines need industrial low frequency on-line uninterruptible power supplies with three-phase four-wire isolation transformers. The power is basically between 80KVA and 160KVA, of which 120KVA is used for CT machines, and 100KVA and 160KVA are used for nuclear magnetic resonance machines.3. According to statistics, medical equipment in general villages and towns in China is disturbed by power supply more than 40 times a month, mainly including voltage changes, power outages (including short-term power outages measured in milliseconds), phase loss, and poor phase balance. Among these interferences, a large part is easy to be ignored because the naked eye cannot detect and distinguish them, but it usually affects the normal and safe use of the equipment.Shenzhen SST Power Co., Ltd.'s medical dedicated UPS power supply is of high quality, reasonable price and first-class service.
