Dual 100 Amp Digital DC Meter Pre-wired Board

Comes pre-wired with 5 foot power-up wires for the digital meter! No other wires are supplied.

Our pre-wired Dual 100 Amp Digital Meter Board allows you to see amperage from two separate components in a system! Typically, two charging or discharging sources cannot be combined into one meter either by electrical or mechanical interference or interruptions.

See your solar panel amperage, hydroelectric amperage, wind turbine amperage, or battery draw amperage. Any two components combined under 100 amps! Pre-wired to a galvanized steel mounting plate, our Dual 100 Amp Digital Meter Board gives you the convenience of not having to find a non-conductive shunt bar mount and takes a lot of the work out of your next project!

Digital Amp Panel Meter Features:

• Two gang switch box and shunt
  
• 100 Amp DC Digital Blue LED Display
  
• With On/Off switch
  
• This meter does not need a separate power supply
  

A highly-efficient yet flexible amp meter which can be used to measure the charge or discharge current in 12, 24 and 48 volt alternate energy systems or other energy sources or loads. No separate power supply is needed! This meter has been designed specifically for alternate energy systems; yet, it also perfect for measuring vehicle, yacht, electric toy, tool or motorcycles having a 12V, 24V or 48V storage batteries.

Advantage over other panel meters by competitors:

• Compared with LCD panel meters, this LED panel meter has a high contrast display with super clear numbers and wide viewing angle.
• Measures Amps to or from a battery bank, energy source or load. (Both positive or negative flow)
• Super convenient operation (DOES NOT need an additional power supply.) Hook up the leads and you are set.
• On/Off Switch -- This meter uses only 30ma to 60ma ( .03 to .06 amps) at 24 volts, or approx. 10ma at 48 volts. If you are like many of us who simply do not like wasted energy, regardless of how small it is, then you will love this meter, as you can simply shut if off when you are not using it.
• Good looking, black matte solid metal face plate
• Shunt is remotely located for direct sensing. This allows the current carrying wires to take a more direct path to the batteries and alleviates the need to route them through the meter case.

Features:

• Large (0.56 inch/14.2mm) easy-to-read blue LED display.
• Wide application range. Can be used to measure the voltage of various batteries ranging from 7.5 to 100VDC.
• Successive approximation-based AD conversion, which is fast and accurate.
• Highly-efficient DC-DC converter, with very low temp rise.
• Completely isolated, super efficient, custom made switch mode power supply.
• Reverse polarity protection..

Specifications:

• Min Input voltage : 8.5 VDC
• Max Input voltage: 100 Volts
• Max Amperage: 100 Amps DC
• Meter Dimensions: 4.2 x 4.2 x 2.2 inches
• Board Dimensions: 11 x 8 x 3.5 inches

Hook up four wires and you are ready to go. Push the switch to turn the meter on. Push again to shut if off.

Tips & Things to Remember in DC Amp Meter Wiring:

• Use a DC amp meter for amp readings
• Don't allow incoming power to exceed the rated amperage (or voltage) of your meter - it may break the unit
• Match the amp rating of the meter to the amp rating of the shunt bar
• Match the millivolts (mv) of the meter to the millivolt (mv) rating of the shunt bar
• The two wires between the meter and shunt bar need to be the same length
• A wind turbine should be connected to a separate meter than the solar panel(s)
• To test the amps or volts of your wind turbine or solar panel system with a handheld clamp on meter, you must use a DC model

Troubleshooting your DC Meter Issues:

• If the needle on the meter is a negative reading, switch the sense wires between the meter and shunt bar
• If the needle on your analog meter is not at zero when there isn't incoming power, you can calibrate it by turning the screw on the front of the meter
• If your digital handheld DC meter isn't giving you an accurate reading, check the batteries in the unit

About DC Volt Meters:

• The positive and negative inputs are typically not marked on the DC Volt Meter. If you connect them to your battery and get a negative reading, simply swap the wires.
• 12 Volt battery systems should use a 15 Volt meter; 48 Volt systems should use a 70-75 Volt meter.
