AILI DC 0-90V 0-30A Voltage Current Energy Power Watt Meter HHO EV Car Motor Boat Solar Wind

The unit is designed to monitor performance most kind of battery systems, it continuously monitors voltage, discharge current, number of power, consumed amp hours, these information leads to more efficient use of the battery, which can enhance battery life and reduce the risk of failure.

Combines many functions in one, Dual display.
*Voltage (V), Power (W), Current (A), Ampere-hour (Ah), Working Hours (H).

Equipped with programmable alarm, to run a generator when needed or to turn off devices when the reading reaches a set threshold (relay required).
An alarm is acknowledged when a button is pressed.
On most of the DCM9040's readings an alarm can be triggered when the value reaches a set threshold.
