Lead-Acid Battery Backup System DC load bank tester 48V string
voltage 300A Current
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
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,
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.
1, Users can setup four parameters to stop discharge: pack voltage,
cell voltage, discharge time, discharge capacity. It can be also
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.
