Monitor Two Battery Banks
Link 20 is a battery monitor that provides complete battery status information for two battery banks simultaneously. A simple and easy-to-use interface displays volts, amps, amp hours, or operating time remaining. Link 20 allows you to select Automatic, Sleep and Scanning modes. Link 20 also measures and reports kilowatt hours and historical battery information such as number of cycles, deepest discharge, and average depth of discharge. It automatically calculates and displays charging efficiency. Since each battery bank has its own battery state LED bar graph, the status of either battery bank can be monitored at a glance. Monitor a house bank and starting bank or two house bank batteries at the same time. Link 20 can be used with 12 or 24-volt systems.
Link 20 Features
User Interface with Graphic and Digital Displays
Link 20's splash-proof front panel allows for hands free operation and performs over 50 different functions. Major functions include:
1. Four multi-colored LED Bar Graph displays battery state-of-charge at a glance for a single battery.
2. A DC Volt display shows specific battery voltage information on the battery bank.
3. A DC Amp display shows the present flow of current in or out of the battery. It displays net amps drawn from the battery for various loads and the charge rate from the charging source.
4. An Amp Hour display shows amp hours consumed. This represents the amount of energy removed from the battery. During battery charging Link 20 compensates for charging efficiency of the battery as it counts back towards 0. Range + 0-1,999.
5. A Time Remaining display provides an estimate of how long a battery can be operated at present load until Link 20 indicates the battery is completely discharged. This is based on a selectable, time-averaged rate of discharge. Range + 0-255.
6. A Select (SEL) button changes a numeric display from volts, to amps to amp hours to time remaining.
7. A Set (SET) button provides entry to the Set Up and Advanced Functions modes.Programmable Advanced Functions
Customize Link 20 to perform specialized functions such as setting Alternative Energy, Sleep and Kilowatt Hour display modes.Easy Installation
Link's patented ratchet ring mounting hardware makes installation easy and fast. The gasket around Link 20 ensures a rattle-free installation. Complete installation instructions come with each Link 20 including instructions for high voltage systems found in electric vehicles.Historical Data Display
Link 20 displays key historical battery information such as charge efficiency, deepest discharge, and average discharge.Front Panel Software Lock
Link 20's Front Panel Software Lock prevents other users from changing set up parameters.Custom Dual Shunt (included)
A dual precision shunt comes with each Link 20. The shunt is a one hundred micro ohm resistor wired into the negative terminal of both batteries. Link 20 senses very small voltage measurements across the shunt one thousand times second in order to calculate average current. Heavy-duty shunts are available for currents that exceed 500 Amps.
