Voltage and Current Data Logger for Power Monitoring

The AIOTHUB Voltage and Current Data Logger measures electrical parameters in real time. It helps you detect fluctuations, prevent overloads, improve energy efficiency, and keep your equipment safe — all from one dependable device.

What Is a Voltage and Current Data Logger?

This logger continuously records voltage and current so you can monitor equipment health, power usage, and electrical performance over time. By studying these trends, you can spot problems early and avoid costly breakdowns.

Calculate Power and Energy

Beyond basic readings, the system calculates power (kW), energy (kWh), peak demand, and load trends. This makes it ideal for energy audits, cost reduction, ISO 50001 compliance, and preventive maintenance.

Detect Problems Early

By analyzing current and voltage trends, you can identify overloaded motors, failing power supplies, loose connections, and abnormal consumption before they cause major failures. Early detection helps you plan maintenance and avoid unplanned downtime.

Real-Time Alerts

Set alerts for over-voltage, under-voltage, over-current, and load imbalance. When limits are crossed, you receive an instant warning by SMS, email, or WhatsApp, so you can respond before equipment is damaged.

Safe and Accurate

Isolated inputs, current transformers, and protective circuits keep operators and equipment safe, even on high-voltage systems. Industrial-grade measurement circuits deliver stable, high-accuracy readings suitable for energy audits and equipment monitoring.

Works for AC and DC Systems

The logger supports both AC and DC electrical systems, making it suitable for factories, solar plants, batteries, and UPS systems. You can install several units across machines and monitor them all from one central dashboard.

Reliable Reporting

View real-time voltage, current, and power on the AIOTHUB web dashboard from anywhere. Export voltage and current logs, power and energy reports, and peak load history in Excel or PDF. Data is stored locally and syncs automatically when connectivity returns, so no reading is lost. The AIOTHUB Voltage and Current Data Logger is designed and made in India with local service and support.

Buyer's guide

How to choose the right voltage & current data logger

Six factors separate a logger that safely protects your machinery and monitors power audit details from one that creates a hazard.

Parameter & range

Ensure the logger supports your electrical values (e.g. 0-10 V for control loops or heavy AC/DC current using external Current Transformers).

Sampling rate

For power trends and load profiles, minutes work. To detect transient electrical spikes or voltage sags, you need sub-second sampling.

Connectivity

Choose a communication model (Wi-Fi, 4G, Ethernet) to stream alerts instantly. Modbus RTU/TCP or MQTT drops into building energy management tools.

Storage & backup

Local flash and SD backup keep your energy audit data continuous through local power grid blackouts.

Compliance

Essential for ISO 50001 energy audits, factory machinery health validation, and building utility reporting.

Power & environment

Use isolated inputs, protective shunts, and high-impedance circuits to ensure safety on active high-voltage panels.

Parameters

One Logger. Complete power metrics.

The AIOTHUB Voltage & Current Data Logger tracks all essential electrical variables to audit consumption and evaluate machinery health.

AC/DC Voltage
