TOMZN 80A DIN Rail Digital Energy Meter (SDM220-ECL) - KWh/Volt/Amp Monitor
Want to know exactly how much power your AC unit, guest house, or high-power workshop is using? High electricity bills can be a mystery. At Abhir-Online, we believe in giving you the tools to see exactly where your money is going. This isn't a complex smart device; it's a professional, reliable tool for one simple, important job: accurate measurement.
Introducing the TOMZN 80A DIN Rail Digital Energy Meter (SDM220-ECL). This is a high-precision sub-meter designed to be installed directly in your distribution box. It monitors a single circuit and gives you a crystal-clear, real-time view of your energy consumption. The bright, backlit LCD cycles through total energy (KWh), real-time Voltage (V), Current (A), and Power (W).
Built with high-performance SMT chips for accuracy and a non-volatile memory that saves your KWh data during a power outage, this is a true "set it and forget it" solution. It's the perfect tool for landlords, homeowners, or anyone who wants to isolate and track the energy cost of a specific high-load circuit.
💡 The Technology Explained (in Simple Terms):
This is a digital sub-meter, not a smart switch.
- Monitoring Only: Its purpose is to measure and display energy consumption. It does not have Wi-Fi or an app, and it cannot be used to turn power on or off remotely.
- Tamper-Proof KWh: The total KWh (kilowatt-hour) reading is permanent and cannot be reset. This is an intentional feature (like a car's odometer) to ensure the consumption data is always accurate and cannot be tampered with.
Key Highlights:
- 📈 Track Your Energy (KWh): Accurately monitor the total energy consumption of a specific circuit.
- 🖥️ 4-in-1 Backlit Display: Automatically cycles to display KWh, Voltage, Amps, and Watts.
- 💪 High Capacity (80A): Perfect for high-power appliances like AC units, water heaters, or small sub-panels.
- 🔒 Tamper-Proof Memory: Non-volatile memory retains KWh readings during power failures. The KWh counter cannot be reset.
- 🛠️ Professional DIN Rail Install: Fits standard 35mm DIN rails (36mm width) for a clean, professional installation.
Product Features and Advantages:
The TOMZN SDM220-ECL is a commercial-grade meter designed for reliability. Its primary advantage is accuracy; built with high-performance, large-scale integrated SMT chips, it provides Class 1 accuracy for dependable readings. The clear, bright white backlit LCD ensures readability even in dark electrical cabinets. Unlike smart devices, its simplicity is its strength—there is no app to crash, no Wi-Fi to disconnect, and no complex setup. Its non-volatile memory and tamper-proof counter make it the most reliable solution for billing or long-term monitoring.
Applicable Applications and Practical Usage Scenarios:
- Sub-let & Tenant Billing: Install one on the circuit for a rental unit, guest house, or shared room to accurately bill tenants for their exact electricity usage.
- High-Power Appliance Monitoring: Find out the true monthly cost of running your most powerful appliances. Ideal for central AC units, water heaters, pool pumps, or EV chargers.
- Workshop & Garage Power: Keep track of electricity consumption from heavy-duty tools and machinery in your workshop or garage.
- Energy Audits: Use it as a tool to identify "energy vampires" and see which circuits are responsible for high electricity bills.

Frequently Asked Questions (FAQs):
- Q1: Is this a smart meter? Can I see the data on my phone?
- A1: No, this is a digital meter (monitor) only. It does not have Wi-Fi or Bluetooth and does not connect to any app. All readings are displayed on the built-in LCD screen.
- Q2: How do I reset the KWh (consumption) counter to zero?
- A2: You cannot. This meter is designed to be tamper-proof, just like your main utility meter. The KWh reading is cumulative and cannot be reset.
- Q3: How do I read my monthly consumption?
- A3: To track monthly usage, simply note the KWh value on the screen on the 1st of the month. On the 1st of the next month, note the new value. The difference between the two numbers is your total KWh consumption for that period.
- Q4: What does the "5(80)A" rating mean?
- A4: This is a standard for energy meters. "5A" is the base current for accuracy testing, and "80A" is the maximum continuous current the meter can safely handle.
- Q5: Will it lose my KWh reading if the power goes out?
- A5: No. The meter has a non-volatile memory that safely stores the total KWh reading indefinitely, even during a power outage.
Mounting: Mounts directly onto a standard 35mm DIN rail inside your electrical panel. It has a 36mm (2-Pole) width.
🛠️ Installation & Setup Insights:
- Electrical Connection / Wiring:
- ⚠️ Safety First: This device connects to mains electricity. Installation must be performed by a qualified electrician in accordance with local safety regulations.
- Wiring: The device is clearly marked for simple in-line installation. Wire the Main Live (L) and Neutral (N) to the top inputs, and connect the Load (your appliance/circuit) to the bottom outputs.
