The Altertek State of Charge Gauge is intended to be mounted behind a bulkhead that simply connects to the battery and load which through coulomb counting accurately calculates the State of Charge of the battery.
The Altertek SOC gauges has an onboard precision coulomb counter which integrates current through a sense resistor (or external shunt) between the battery’s positive terminal and the load or charger.
Measuring both current and voltage allows the state of charge to be accurately calculated, rather than estimated from the voltage alone. The SOC gauge can give an accurate reading down to 1% accuracy.
State of charge is displayed using 10 coloured LEDs for quick visual indication.
The SOC Gauge features programmable high and low thresholds and the capacity of the battery can be selected by the installer without any additional equipment.
If a programmed threshold is exceeded, the device communicates an alert using the on board LEDs and external alarm contacts so diagnosis of the problem is fast and easy.
The product can be set to be permanently on or display when the onboard button is pressed to save power.
The onboard current sensor can measure a maximum of 25A load or alternatively an external Shunt can be added to measure loads up to 500A.
