Kstar YDC3310 Three In Three Out UPS Power Supply 10KVA/9KW 380V Stable Voltage Uninterruptible Power Supply Equipment

Description :

  YDC3310 UPS power supply is an uninterruptible power supply device designed specifically for critical loads, mainly solving the problem of damage to precision instruments and servers caused by power interruption and voltage fluctuations. This model adopts a three in three out topology structure, with a rated capacity of 10KVA/9KW, and both input and output are 380V three-phase electricity. It is suitable for typical working conditions such as data centers, medical imaging rooms, and industrial automation control centers that require extremely high power continuity. As an online UPS power supply under the Coaster brand, it can achieve zero time switching to battery power supply in case of grid abnormalities, ensuring uninterrupted operation of backend loads and effectively preventing data loss or hardware damage. It is the core infrastructure for ensuring business continuity.

  YDC3310 UPS power supply follows strict electrical safety and electromagnetic compatibility standards, and has a complete protection mechanism. Its input voltage range is wide, usually supporting three-phase input of 304V-478V (380V ± 20%), with a frequency synchronization range of 50Hz ± 5%, ensuring stable operation even in harsh power grid environments. The output power factor is 0.9, and the full load efficiency can reach over 90%. In terms of overload capacity, 105% -125% load can run for 10 minutes, 125% -150% load can run for 1 minute, and if it exceeds 150%, it will immediately switch to bypass or stop protection. The battery pack is usually equipped with 32 12V lead-acid batteries, with a DC bus voltage of 384V, and the charging current can be automatically adjusted according to the battery capacity. The overall protection level of the machine is usually IP20, with a working temperature of 0-40 ℃ and a humidity of 0-95% without condensation. It meets common certification requirements such as CE and ISO9001.

  When selecting YDC3310 UPS power supply, it is necessary to clarify the load nature and power requirements. This model is suitable for mixed loads of inductive, capacitive, and nonlinear loads, such as server clusters, network switches, monitoring hosts, etc. If the load is only a regular office computer and the power is small, a backup or online interactive low-power UPS can be selected to reduce costs; If the load is a high-power motor or equipment with extremely high instantaneous surge current, it is necessary to consider equipping isolation transformers or selecting a parallel system with higher redundancy. Compared with single-phase input UPS, the three in three out design of YDC3310 can better balance the load of the three-phase power grid, reduce harmonic pollution to the mains power grid, and is suitable for large and medium-sized computer rooms that already have three-phase power access conditions. When purchasing, it is necessary to confirm the backup time requirements in order to configure the corresponding number of external battery packs.

  The installation of YDC3310 UPS power supply needs to be operated by professional electricians to ensure correct input and output phase sequence, with a grounding resistance of less than 4 ohms, to ensure personal safety and equipment lightning protection effect. In daily maintenance, it is recommended to check the operation of the fan and the cleanliness of the filter every quarter, and conduct a battery internal resistance test or charging and discharging drill every six months to prevent power failure caused by battery aging. Common faults include flashing of the mains indicator light (input voltage exceeding limit), battery alarm (battery undervoltage or open circuit), etc. Specific error codes can be viewed through the LCD panel. When the battery is idle for a long time, it should be recharged every 3-6 months to avoid sulfation affecting its lifespan. Proper use and maintenance can significantly extend the service life of UPS power supply and battery pack, and reduce overall operation and maintenance costs.
