Voktta 100A DC Power Meter User Manual

1. Introdução

This manual provides detailed instructions for the installation, operation, and maintenance of your Voktta 100A DC Power Meter. This device is designed to accurately measure DC voltage, current, power, and energy consumption in various applications, including RVs, solar systems, and battery monitoring. Please read this manual thoroughly before use to ensure proper function and safety.

2. Informações de segurança

• Ensure all power is disconnected before installation or wiring to prevent electric shock.
• This device is intended for DC circuits only. Do not connect to AC power.
• Observe correct polarity (+/-) during wiring to avoid damage to the meter and connected equipment.
• Use appropriate wire gauges (30-12 AWG copper wires recommended) for connections to handle the expected current.
• Não exceda o vol máximotage (100V DC) or current (100A) ratings.
• Mantenha o dispositivo longe de umidade, poeira e temperaturas extremas.
• Do not attempt to disassemble or modify the meter. Refer all servicing to qualified personnel.

5.1 Basic Wiring Instruction

The meter requires a 100A/75mV shunt for current measurement. The shunt must be installed in series with the load. The meter itself connects with four wires (not included) to the shunt and the power source.

1. Etapa 1: Install the 100A/75mV shunt in series with the DC circuit, between the power source (e.g., battery) and the load. Ensure correct polarity.
2. Etapa 2: Connect the meter to the shunt and the power source using four wires. The meter's small wires are for its own power supply and voltage measurement, while the shunt handles the main current. Recommended wire gauge for connections to the meter is 30-12 AWG copper wires.

5.2 Solar System Wiring Instruction

This diagram illustrates wiring for a solar system where an inverter connects directly to the battery. The meter's four wires do not carry large current; they are for measurement and power. Any copper wire from 30 AWG to 12 AWG can be used for these connections.

You do not need to wire both meters if monitoring a solar system; just connect the voltmeter(s) to monitor the specific parameters you require.

6. Instruções de operação

• Ligar: Once correctly wired, the meter will power on and display real-time voltage, corrente, potência e energia acumulada.
• Controle de luz de fundo: The backlight can be manually toggled on or off using the button on the front panel.
• Over-threshold Indication: If the active power exceeds a predefined threshold, the backlight and power display will flash to alert the user.
• Energy Data Reset: To reset the accumulated energy (kWh) data, press and hold the button on the front panel for approximately 5 seconds until the energy reading resets to zero.
• Memória de desligamento: The meter automatically saves all settings and accumulated energy data when power is disconnected. This data will be restored upon power-up.

7. Manutenção

• Limpe a tela e casinLimpe com um pano macio e seco. Não utilize produtos de limpeza abrasivos ou solventes.
• Verifique regularmente todas as conexões da fiação para garantir que estejam seguras e livres de corrosão.
• Assegure-se de que o ambiente operacional esteja dentro das faixas de temperatura e umidade especificadas.

8. Solução De Problemas

• Nenhuma exibição:
  • Check if the power supply to the meter is connected correctly and within the 6.5-100V DC range.
  • Verifique se todas as conexões de fiação estão seguras.
• Leituras incorretas:
  • Ensure the shunt is correctly installed in series with the load and its connections are tight.
  • Check for correct polarity of all connections.
  • Verify that the current does not exceed the 100A rating of the shunt and meter.
• Backlight Flashing:
  • This indicates that the active power has exceeded the set threshold. This is a normal warning function.
• Energy Data Not Resetting:
  • Ensure you are pressing and holding the reset button for at least 5 seconds.
