General Description
Thanks for choosing TBB product.
The BM series battery monitor features microprocessor controlled combined with high resolution
measuring system for Lead Acid battery voltage and charge/discharge current. With built in
software, BM series can calculated consumed AH/KWH and remaining AH/KWH, and display
battery voltage and battery current as well.
BM could record all battery activities since the first installation (max 200 records). Apart from
discharging and charging, multiple other factors are considered including battery size, age ratio
of battery etc. With shunt, even the smallest leakage current can be detected and recorded to
guarantee the accuracy.
Compared with conventional indicating meters, small current can be measured and read exactly
with this device. With this feature, latent consumers (insulation fault, wrong connections,
standby unit etc) can be recognized immediately. Meantime, through additional sensor second
battery voltage can be measured and displayed.
With the optional DOD protection unit, battery low voltage protection level can be programmed
and alarm cam will be sent once reaching the limit to avoid battery damage due to deep
discharge. In the meantime, it can be used to drive the battery protection device to shut off the
battery against further discharge.
