    JET-AG 48B30 DC load bank tester


    What items should Lead-acid batteries be checked frequently?
    1, the floating voltage
    2, if there is looseness, heat generation and corrosion in the connection. Must be cleaned in time and anti-rust. Loose connection will cause burning.
    3, if there is leakage and deformation of the battery shell, and if there is heating.
    4. if there is acid mist escaping around the pole and safety valve (frost phenomenon).


    JET-AG 48B30 DC Load Bank Tester, is for 48V battery bank, and discharge current is max 300A. It performs constant current and constant power discharging to help us know batteries’ capacity exactly, and real-time display the parameters during testing. Load Bank is widely used in telecommunication station, data center, UPS system and etc.


    People also called them as:

    DC load bank,

    Constant current load bank,

    48V load bank,

    DC capacity tester,

    Constant Current discharger,

    Portable load bank,

    Battery capacity tester,

    Battery discharger.


    Two Key Functions:

    1, On-line monitoring function: include pack voltage, cell voltage, pack charge/discharge current, pack charge/discharge capacity, pack monitoring time, and etc.

    2, Discharge function: constant current discharge. Discharging can be stopped by the set parameters or artificially.


    Key Features:

    1, Users can setup four parameters to stop discharge: pack voltage, cell voltage, discharge time, discharge capacity. It can be also stopped artificially.

    2, No need correcting voltage manually.

    3, 100 groups of on-line monitoring data and 100 groups of discharge data can be saved.

    4, It can be controlled and real-time monitored by computer via RS232, meanwhile performs pattern analysis in computer.

    5, Export data via RS232 or U disk.

    6, It cannot be started if the voltage is inconsistent.

    7, When it is abnormal, it stops testing automatically.

    8, 5.7-inch color touch TFT screen with high performance.

    9, Powerful analysis software can generate voltage/current histogram, curve chart and test report automatically.
