For Proteus | Zmpt101b Library

A: Some libraries are backward-compatible, but Proteus 7 has limited SPICE features. Search for legacy-specific ZMPT101B models.

If you are looking for a drag-and-drop component in Proteus, you will be disappointed. However, if you build the simple circuit using a Transformer and Resistor, the simulation is highly effective for code logic testing.

Final Recommendation: Don't waste time hunting for a .LIB file. Build the equivalent circuit: zmpt101b library for proteus

The ZMPT101B module essentially consists of a Voltage Transformer and a Burden Resistor. It steps down high voltage (up to 250V AC) to a low, measurable AC voltage (usually around 2.5V AC riding on a DC offset).

To build this in Proteus, follow these steps: A: Some libraries are backward-compatible, but Proteus 7

Pros:

Cons:

Here’s a simple simulation setup:

Note: The model outputs a scaled AC waveform centered around 2.5V (for single-supply operation). You’ll need to sample it and compute RMS in your firmware. Cons: Here’s a simple simulation setup:
