Meatest M133C Power & Energy Calibrator

The Meatest M133C is a high-precision AC/DC power and energy calibrator designed for the calibration of power meters, energy meters, transducers and power quality analysers. With a wide frequency range from 15 Hz to 1000 Hz, simulated power up to 3× 18 kVA (AC) and 25.2 kW (DC), and support for both single- and three-phase configurations, the M133C offers a versatile and powerful solution for laboratories and industrial test environments.

Two versions: single-phase and three-phase

The M133C is available in two variants:

> M133C 1F (single phase): Ideal for applications requiring a compact but powerful calibration solution.
> M133C 3F (three-phase): Suitable for the calibration of dynamic 3-phase power meters and mains analysers.

Both models offer precision, fast setting and a wide range of test capabilities, making them applicable in R&D laboratories, industrial quality control and metrology institutes alike.

Striking accuracy and versatility

The M133C offers a phase angle accuracy of 0.01°, contributing to accurate precision calibrations even with complex loads. Harmonic and inter-harmonic simulation up to 63rd order enables detailed analysis on power quality instruments. The three-phase variant can emulate different measurement configurations, such as 3-wire and 4-wire systems, allowing testing of network configurations such as Y (star), Δ (delta) and split phase networks. Floating current outputs allow users to calibrate 3-wire power meters directly without an external reference connection. The optional current coil allows testing of current clamps up to 2250 A, which is a crucial feature for industrial applications and smart-grid components.

Integrated transducer calibration and built-in multimeter

One of the key features of the M133C is the built-in process multimeter, which allows measurement of both the input and output of transducers including electricity meters, grid analysers and smart metering systems in modern power systems. This saves time and minimises the need for additional measurement equipment, making the calibration process more efficient.

Comprehensive functionalities and test capabilities

With its broad functionality and high accuracy, the M133C is ideal for:

> Calibration of power and energy meters (up to 18 kVA per phase).
> Power quality tests including voltage dips, swells and flicker simulation.
> Emulation of mains disturbances to test the stability of metering systems.
> Transducer calibration with simultaneous measurement of input and output.
> Calibration of current clamps up to 2250 A with optional coil.
> Testing of industrial power and energy storage systems.
