Din-Rail Digital AC Energy Meter (Voltage, Current, kWh Monitor)

1. Product Overview

This highly efficient Din-Rail AC Digital Meter is engineered for precise 3-in-1 electrical monitoring. It accurately measures and displays AC Voltage, Current, and Active Energy (kWh) in real-time. Designed to meet diverse project requirements, it is available in two display versions: a high-brightness LED model and a crisp LCD model. With a compact 36mm width (2-module size) and up to 100A direct measurement capacity, it is the perfect cost-effective solution for industrial sub-metering, residential distribution boxes, and building automation.

2. Six Key Features

• 3-in-1 Core Measurement: Streamlines your panel by combining a voltmeter, ammeter, and energy meter into one single, compact device.

• Dual Display Options (LED/LCD): Choose the bright LED version for excellent visibility in dark environments, or the LCD version for crisp readouts in well-lit conditions.

• Smart Auto-Cycling Display (LED Model): The LED version features an intelligent auto-cycle function that alternates between the high and low digits of the energy (kWh) reading, ensuring complete data visibility.

• High Capacity & Precision: Measures up to 100A directly without an external Current Transformer (CT), maintaining a strict high accuracy of ±1%.

• Optional RS485 Interface: Easily upgradeable with an RS485 communication port, allowing seamless integration into remote monitoring systems and SCADA networks.

• Standard 35mm DIN-Rail Mount: The 36mm-wide housing easily snaps onto any standard 35mm DIN rail, saving valuable space inside distribution cabinets.

4. Application Scenarios

• Residential Sub-Metering: Ideal for monitoring electricity usage in rental apartments, dormitories, or tenant spaces.

• Industrial Equipment Monitoring: Track the power consumption and operating voltage of specific machines on the factory floor.

• Commercial Distribution Panels: Perfect for office buildings and retail stores requiring basic yet reliable power tracking.

5. Frequently Asked Questions

Q1: What is the main difference between the LED and LCD versions? A: Both versions offer the same ±1% measurement accuracy. The LED version features bright red glowing digits, making it perfect for dimly lit industrial environments or dark distribution boxes. The LCD version provides a traditional, crisp black-on-green digital readout, which is highly readable in well-lit areas.

Q2: How do I read the energy (kWh) on the LED version since the screen is compact? A: The LED model uses a smart auto-cycling feature for the energy reading. Because the energy value can reach up to 99999.9 kWh, the display will automatically alternate between showing the “high digits” and “low digits” of your total energy consumption, ensuring you get the complete reading easily.

Q3: Do I need to purchase a separate Current Transformer (CT) for this meter? A: No, you do not need an external CT. This meter is designed with an internal pass-through structure that can safely measure currents up to 100A directly. You just need to pass the live wire through the designated hole on the meter.

Q4: Can I use this meter on a 110V power system? A: Yes, but you must select the correct voltage version. We offer three voltage ranges: AC 70~150V (for 110V/120V systems), AC 160V~270V (for 220V/240V systems), and a wider range of AC 80~270V. Please specify your grid voltage when inquiring.

Q5: How can I reset the energy (kWh) data back to zero? A: Resetting the data is quick and secure. Simply press and hold the “CLR” (Clear) button on the front of the device for 10 seconds. This long-press requirement prevents accidental resets.
