This Kilowatt Hour Meter is used for private metering as it is not NMI-approved (billing applications)

The Tesla ADM100TC is a 3-phase kilowatt-hour meter designed for accurate energy tracking in high-load applications. Supporting up to 100A and operating on 230V/400V AC, this meter is ideal for commercial and industrial installations. It features DIN rail mounting for easy integration into electrical panels and has a precision class of 2 for reliable readings.

With an operational voltage range of 70-130%Ub and an internal power consumption of ≤2W/10VA, the ADM100TC ensures efficient energy measurement while minimizing power loss. It is built to withstand 2kV AC for one minute and operates within a frequency range of 50-60Hz ±10%, making it a durable and stable choice for energy monitoring.

• 3-phase kWh meter designed for measuring energy consumption in 230V/400V AC circuits.
• 20(100)A → Base: 20A, Max: 100A per Phase
• DIN rail mounting allows for quick and secure installation in electrical panels.
• Precision class 2 ensures accurate and consistent energy readings.
• Wide voltage range operates from 70% to 130% of nominal voltage.
• Overvoltage protection withstands 2kV AC for one minute for enhanced safety.

Q: What does Rated Current (A) 1.5(6)A/CT, 3(6)A/CT, 5(30)A, 10(60)A, 15(90)A, 20(100)A, mean?
A: Explanation of Each Format

1. 5A/CT

• CT stands for Current Transformer.
• This meter is designed to work with external current transformers and expects a 5 Amp secondary input from the CT.
• Commonly used in high-current installations (e.g. 200A, 400A) where it’s not practical to run full load current directly through the meter.

Examples: 5(30)A, 15(90)A, 20(100)A

This format shows both the base and maximum current ratings:

• x = base (nominal) current – the expected continuous load
• y = maximum current – the peak load the meter can safely handle

Examples:

• 5(30)A → Base: 5A, Max: 30A
• 10(60)A → Base: 10A, Max: 60A
• 15(90)A → Base: 15A, Max: 90A
• 20(100)A → Base: 20A, Max: 100A

Why So Many Options?

These options represent different variants of the ADM100TC meter, tailored to suit a range of installation needs:

• 5A/CT model – For high-current loads using external CTs
• Direct-connect models – For loads up to 15A, 30A, 90A, or 100A with no CTs required

What You Should Choose?

• If you’re metering a sub-board or circuit under 100A, go with a direct-connect model like 20(100)A
• If you’re metering a large service (e.g. 200A or more), use the 5A/CT model with CTs rated appropriately for the expected load.
