Coaster YDC3310 rack mounted UPS external battery pack stabilized emergency backup power supply

Description :

  The Kodc3310 UPS external battery pack is an energy storage expansion unit designed specifically for uninterruptible power supply systems, mainly to solve the problem of continuous power supply to critical loads during power outages or voltage fluctuations. The device is connected to the host through a DC bus and seamlessly switches to battery powered mode in the event of a power outage, ensuring that sensitive loads such as servers, network equipment, medical instruments, etc. do not crash and data is not lost. As the core component of a stable emergency backup power supply, it is suitable for working conditions that require long delay backup time, making up for the shortcomings of insufficient built-in battery capacity in the host and ensuring business continuity.

  The Coaster YDC3310 model typically adopts a standard rack mounted design, suitable for installation in 19 inch standard cabinets, saving room space and facilitating unified cabling management. The shell is mostly made of high-strength cold-rolled steel plate or flame-retardant ABS engineering plastic, which has good heat dissipation structure and protection level. Internally connected multiple high-performance valve regulated lead-acid batteries (VRLA) with low self discharge rate and high energy density characteristics. The execution standard complies with GB/T 7260.3 and YD/T related communication power specifications, and has passed ISO quality system certification. The typical working temperature range is 0-40 ℃, supporting wide voltage input to adapt to complex power grid environments, ensuring stable output of DC power even under harsh working conditions.

  When selecting, it is necessary to clarify the compatibility of the host model. The Coaster YDC3310 external battery pack is specifically designed for online UPS hosts in specific power ranges and cannot be mixed with other brands or incompatible series. If a longer backup time is required, expansion can be achieved by connecting multiple battery packs in parallel, but it is necessary to confirm whether the charging current of the host meets the requirements. Not suitable for high temperature, high humidity, strong corrosion or severe vibration environments. Compared with built-in batteries, the advantages of external battery packs are convenient maintenance and replacement, as well as flexible expansion; Compared with ordinary lead-acid batteries, its supporting BMS management system is more complete, which can monitor the cell voltage and internal resistance in real time, avoiding the risk of overcharging and overdischarging. When purchasing, it is necessary to verify that the DC voltage level is consistent with the host.

  When installing the Keda YDC3310 external battery pack, be sure to disconnect the host from the mains first and use insulated tools to prevent DC arc short circuits. It is recommended to install it at the bottom of a well ventilated and load-bearing cabinet to maintain front and rear maintenance space. Daily maintenance requires checking the terminal fastening situation every quarter and conducting a charge and discharge test every six months to activate battery activity and prevent sulfurization failure. The typical service life is 3-5 years. When the backup time is significantly shortened or the battery bulges and leaks, the entire set should be replaced in a timely manner. Common faults include uneven individual voltage and poor oxidation contact of the connecting strip. The fault point can be quickly located through the monitoring panel alarm information. Regular cleaning of dust can help extend the service life of the equipment.
