Battery monitor for 12V Lead Acid

nnnn

Lead acid batteries can be damaged if the voltage

nnnn

is too low for a long time. To know when the

nnnn

batteries needs charging, you can use a battery

nnnn

monitor. The Battery Monitor is designed for 12V

nnnn

battery voltage, and the device is sensing the

nnnn

battery voltage via the input cables. Green LED

nnnn

means that the battery voltage is normal.

nnnn

The Battery Monitor can also control external

nnnn

devices / indicators (eg. Relay) which can display

nnnn

the battery level. When everything is OK, the battery

nnnn

monitor drives current through the external equip-

nnnn

ment, (sink, via Out4 and / or Out3).

nnnn

When the battery voltage decreases, LED goes

nnnn

from Green to Orange. Out4 goes from Low (sink,

nnnn

means conducting current) to "Open Collector",

nnnn

(not conducting current). When the battery volt-

nnnn

age decreases even more, LED goes from Orange

nnnn

to Red. Out3 goes from Low (sink) to "Open

nnnn

Collector". When the battery voltage rises again,

nnnn

the LED goes from Red to Orange and finally to

nnnn

Green. Out3 and Out4 go from "Open Collector"

nnnn

to Low (sink) again, but it is a hysteresis at

nnnn

ca. 0.2 V.
