Precision DC Power Meter – Watt Meter and Power Analyzer with Powerpole Connectors

This easy-to-use DC power analyzer is designed to monitor the eight critical electrical parameters for system safety and performance: Amps, Volts, Watts, Amp-hours, Watt-hours, Peak Amps, Minimum Voltage (Sag), and Peak Watts. With a measuring capacity of up to 60V and 100A, a high-contrast green backlit LCD, and automatic reset at startup, this watt meter is an essential tool for anyone working with batteries, solar panels, chargers, or DC power systems.

Installation Setup & Wiring

• Red source wire (+): Connect to positive battery/source terminal
• Black source wire (–): Connect to negative battery/source terminal
• Output leads: Connect to the DC load
• Unit comes with Anderson Powerpole connectors pre-installed

Watt Meter Display

Startup Screen: Each time power is applied (or auxiliary input is used), the meter resets Amp-hours, Watt-hours, Peak Amps, Minimum Volts, and Peak Watts to zero.

Real-Time Parameters:

• Amps (A): Average current draw
• Peak Amps (Ap): Maximum current since startup
• Volts (V): Average system voltage
• Minimum Volts (Vm): Lowest voltage (sag) since startup
• Watts (W): Average power (Amps × Volts)
• Peak Watts (Wp): Maximum power draw since startup
• Amp-hours (Ah): Total charge delivered
• Watt-hours (Wh): Total energy delivered

Values are shown on the green LCD screen, with key data displayed continuously and others cycling every second.

Auxiliary Power Connector (Optional)

• Allows accurate measurement down to 0V by powering the meter externally
• Improves accuracy since the meter does not consume power from the source/load circuit
• Uses only 2 of the 3 included wires (see housing for (+) and (–) markings)

Typical Applications & Connection Examples

1. Load Testing: Connect between a DC source (battery, solar panel, or power supply 5–60V) and any DC load.
2. Low Voltage (<5V) Testing: Use the auxiliary connector for precise measurements below 5V.
3. Battery Charging: Place the battery on the load side when measuring charging current and capacity from a charger.

WARNING

High-power electrical systems can be dangerous. Always take proper precautions when working with batteries, chargers, or power supplies.

• Do not exceed rated specifications (60V / 100A)
• Avoid short circuits — risk of fire, explosion, or personal injury
• Ensure proper wire sizing for high current loads
• Misuse, overloading, or shorting the meter will cause damage and void the warranty
