Adjustable Battery Gauge/Hour Meter 12/24 volts DC is a great product and we recommend it to you. The customers who have tried the product out have nothing but excellent things to say about Adjustable Battery Gauge/Hour Meter 12/24 volts DC.
- Adjustable lower voltage range to match gauge to the battery pack.
- Hour meter for monitoring hours of operation.
- Separate connection to illuminate the display. Prevents drawing down battery.
- Internal relay for powering auxillary equipment.
- The relay will open at ~20% charge left on the battery to save battery.
Product Description
A lot of engineering packaged in a small gauge.
This series of battery gauges are multi-functioning devices ... adjustable voltage range, separate controls for turning on the display and hour meter and an internal relay for powering auxiliary devices.
The battery gauge "empty" voltage reading can be adjusted to closely match the gauge to the actual battery level of charge. Seven battery voltage ranges can be selected for for each voltage range; 12, 24, 36 and 48 volt operation. See bottom of listing for range specifics
The gauge can be connected directly to the battery but no display will show until a separate lead wire is taken to plus volts. The gauge is monitoring the battery all of the time. By having a separate connection to illuminate the display, it stops the battery from discharging if left for extended periods not connected to a battery charger.
Another connection is used to enable the hour meter. Therefore it is possible to view the battery state of charge, but not accumulated hours until it is desired to do so.
An internal relay allows powering auxiliary devices consuming up to 1 Amp. The relay is normally closed and opens to turn off the device being operated when the gauge displays ~30% power remaining. This is done in an attempt to prevent the battery from becoming completely discharged.
