JLD404 Programmable Battery Meter


This Amphour Meter is new to our line of products, and fills an important niche. In addition to displaying volts, amps, amphours, this meter also can be programmed to switch two internal relays at different rates of current, voltage, or amphours. These could be used to sound an alarm at a low voltage for example, or to shut off a charger enable at a higher voltage.  Optional 500 amp shunt is available. These are not splash proof so they need to be mounted below deck if used on a boat. 

  • Size: 96mm x48mm x62mm
  • Output Relays: 3A@125VAC, 3A@14V DC
  • Metered DC input up to 500V
  • Power: Isolated 12-32V DC



If using your own shunt that is different than our 500amp/ 75mv, you will need to adjust the meter for an accurate current reading. To calibrate for a 50mv shunt you multiply the amp setting by 1.5. For example 500A@(50mv) X 1.5 = 750A@(75mv). So for a 1000A (50mv) shunt enter 1500 amps.
