Watt/Amp Monitor 200A

This High Precision Watt/Amp meter and power analyzer allows you to clearly understand all aspects of current in Amp,Watt and Voltage etc that is being supplied to a battery or from a source such as Charger , Solar Panel or other DCDC charge sources. Do you really know the charge rate going into your power unit such as a Nomad. The biggest confusion people have when charging from a solar panel or charger is how much amp or current is actually going into the unit, and how the charge rate changes as the battery gets closer to charge, and also the elements that can effect the charge rate. This useful analytic tool helps you understand all your accessories and charge rates, so you can predict timelines for charge and discharge etc.

An inexpensive but very useful tool, especially if you have gone to the effort of elaborate camping or off-grid systems, If you want to understand your whole set up , you really should consider grabbing one of these. Comes all ready to go including the Anderson style connections. Available through us or National Partners contact@renewablebiz.com.au

Safety Precautions: Shorting a rechargeable batter or Watt Meter connected to a rechargeable battery can supply huge currents , potentially causing fire or Damage to equipment. Ensure that all wiring and connections are rated to handle the input or output currents, and are properly assembled in each application such as ACDC/DCDC/Solar Charging and so on. The responsibility is the user to ensure the ratings of all cabling and fusing is correct.
 
 
 
 
Input Voltage & Current Handling Limitations: The Watt Meter is designed to be safe in systems using less than 60 V and carrying currents up to 130 A. Caution: Exceeding these limits will damage the Watt Meter and may cause injury.

Wiring, Connections and Applying Power: Warning - Loose connections can cause component damage!only switch power between meter & Load when secure. The Red Source wire goes to the positive + battery or other device terminals and Black to Negative -. User is responsible for attaching connectors rated to handle the voltage and current expected in the application. Qualified Individuals should make sure if any high current applications are involved. Verify there are no exposed wire or connectors that may short circuit before connecting a battery or power source to the Watt Meter. By connecting an auxiliary battery (e.g. a receiver battery) of 4.8-60V to the Source 3-pin connector, the Watt Meter can measure down to 0V.

Display Screen: Startup Screen -  Each time power is applied across the Watt Meter, Leads or (Auxiliary power connector) a start up screen with Logo is briefly displayed and peaks, minimums. Ah & Wh are reset to 0. The display then changes to measurement screen.

Measurement Screen: The measurement screen continuously displays Amps, Volts and Watts. All the other measured values are presented sequentially, every 2 seconds, in the data queue position of the display. Data values are identified by their units (Ah, Wh, Ap, Vm, Wp). All measurement screen values are updated every 0.4 seconds.

The Measurement Screen Layout: Amp, Volts, Watts & Data Queue. The data queue shows AH, Wh, Ap, Vm, Wp in sequence.
(Current) Amps & Amps A, Ap: Only current from the SOURCE to Load is measured. Amps value displayed us the average current over the last screen update interval. Peak Amps value (AP) display is the Maximum current drawn from the LOAD side (Or Charge Rate) Since the Meters startup. Peaks lasting only a fraction of a second, can be captured. Supplying the auxiliary power with voltage greater than the meter is measuring, removes the Meters operation current form measurements. To reduce meter heating, measure currents over 65amps for reduced time and consider using connectors that can handle such larger currents. Please note the grey Anderson Type connectors are rated to 50 Amp.

(Voltage) Voltage & Minimum Volts, V, VM: The display volts value is the average voltage over the last screen update interval, The displayed minimum volts value (vm) is the Minimum voltage measured on the SOURCE side, since startup screen ended. The volts value is measured on the SOURCE side.

(Energy) Watt - Hours Ah: The displayed value is the total energy delivered in Watt-Hours since the startup screen ended. It is measured on the LOAD side. For accurate results, be careful not to interrupt the SOURCE connection to the Watt Meter during an energy measurement.

(Charge) Amp -Hours Ah : The display value is the total energy in Amp-hours (x1000=mAh) delivered since the startup screen ended. It is measured on the LOAD Side. For accurate results, be careful not to interrupt the SOURCE connection to the Watt Meter during a charge measurement.

(Power) Watts & Peak Watts W, Wp: The displayed value is the average power delivered in Watts (=Volts XAmps) over the last screen update interval. The displayed peak Watts value (Wp) is the maximum power drawn on the LOAD side, since the start up screen ended. Watts values are measured on the LOAD side.

BUSING Watt Meter: You can think of the Watt Meter as a set of jumper leads. Connect in the same way and you can measure what the jumper wires are connected to . Like jumper wires, the Watt Meter is essentially a direct connection between same coloured SOURCE and LOAD wires, i.e. Both the Source and Load leads are electrically hot when the battery is connected to either side. Current flows from SOURCE to Load, make sure connections are secure to prevent damage.
Example use : #1 Battery on Source side, connect to motor speed controller (ESC) and motor on load side, with ESC on, the Watt Meter shows the current in to the motor, voltage and power at the battery and accumulates the Ah and Wh while the motor is running. Example use:  #2With a battery charger on the Source side and a battery pack (Such as a Nomad )on the Load side, the Watt Meter shows the charging current into the Battery Pack, the voltage and charging power at the battery, and accumulates the charge (Ah) and energy (Wh) into the battery.

Functions: Watt Meter and Power Analyzer
Measures 8 Parameters key to electric power safety & performance. Use it to : Prevent peak currents damaging battery, Motor Controller, Motors, Wiring and Connectors. Verify sufficient operating voltage under load. Set cutoff voltages, check battery capacity & health. Balance Battery Cells. Confirm proper battery charger operation. Detect receivers and actual operating current so as to make sure whether an UBEC is needed.
