Over-Current Disconnect
OCD Trip Threshold: The current in amperes above which the power relay disengages.
OCD Filter (ms): The duration of time the current has to be above the trip value in order to disengage
the relay. In order to function as a circuit breaker this should be set to a very low value between 0ms ..
20ms. Larger values will slow down the reaction to over-current. In some instances, this could be useful.
Auto-Off Timer: If enabled the power will turn off automatically after the specified time since it was turned on
has passed. This effectively becomes a turn-off timer.
Battery Fuel Gauge
Battery Chemistry: The chemistry of the battery used.
Number of Cells: Number of cells of the battery. 12V Lead Acid batteries have 6 cells. 12V LiFePO
4
have
4 cells. If you have batteries connected in series, add the number of cells in each of them. If batteries are
connected in parallel the number of series cells does not change.
Battery Capacity: Battery capacity in Ah. If batteries are connected in parallel, add up their capacities. If
batteries are connected in series the capacity does not change. (only the number of cells in series does)
Disconnect on Fuel Gauge: The device will disconnect power (turn the relay off) when the battery state
of charge becomes lower than this threshold (in percentage). The “Invert RELAY logic” option can invert
this behavior.
Connect on Fuel Gauge: The device will re-connect power (turn the relay ON) when the battery state of
charge becomes higher than this threshold (in percentage). The “Invert RELAY logic” option can invert
this behavior.
Default Factory Settings. The device can always be reset to the default configuration using the
PowerMon app. To do this, connect to a device, tap the right corner menu (iOS) or right corner menu and then
About (for Android). Tap on Factory Reset.
WARNING: When resetting to the factory defaults, all custom settings and timers will be erased,
including the device calibration and the battery fuel gauge internal state. The device Bluetooth name will not
be changed.
