Amp-hour meters


These digital meters measure Ampere hours (Ah) or energy used or generated in a system, so giving an accurate indication of the battery state of charge at any given time. Useful for assessing stored battery power, spare capacity, performance or fault detection.

Starting at zero for a fully charged battery Ah consumed are shown as a negative display, charging Ah are added until the reading is back to zero.

Measurement is via an external current shunt which is usually sited in the main negative feed to/from the battery. Signal cables are then taken to the remotely mounted display.

They act like a battery ' fuel gauge '!

Using one of these meters increases awareness of battery state of charge and electrical usage, translating into longer battery life and smarter use of your power resource, - every battery system should have one! For optimum use:

  • Locate where easily seen eg. in a living area rather than the battery room.

  • Educate yourself about how much each appliance uses by observing amps reading with appliance off and then on.

  • Check Amp-hours reading daily to see that you are keeping within your energy budget.

Battery charge indicators


These are included in many charge controllers and give an easy to understand indication of how full batteries are, whether they need to be charged, and whether to turn off your charging source. While in no way as useful or accurate as proper metering they give a simple measure of system performance.

Link 10 Meter


Link 10 MeterThis small digital state-of-charge meter displays Volts, net amps charging or consumption, net Amp-Hours & Kilowatt hours consumed and how much operating time remains. Time-Remaining is based on your choice of present consumption, average consumption in last 6 minutes, 30 minutes or 24 hours.

Four multi-colour LED Bar Graph acts as an at-a-glance ‘fuel gauge’. Indication of low battery and that the battery has reached the charged parameters.



DATA mode displays charging efficiency, number of recharge cycles, average depth and greatest depth of discharge.

Options:
RS-232 computer output for data logging;
Relay output for generator starting;
temperature sensing for temperature compensation. For 12 or 24 V systems. Prescaler allows use in systems up to 100VDC.

Consumes 150mA (20mA in bar graph only sleep mode)
Mounts in 2" (52mm) diameter hole, 2.9" (75mm) deep.
500A shunt included. Accuracy +/- 0.5%.
