Introduction

The CPKM3000Meter is an active energy measurement device which can measures active energy being delivered from the grid. It has been designed to fit and be installed within a custom made AC EVClosed Electric Vehicle charger which shall provide a sealed and controlled environment (at least IP54).

Voltage Configurations

  • 230/400 V, 50 Hz, 3p+N meter, which can work as a 3ph or 1ph meter.

  • 230 V, 50 Hz, 1ph + N meter, which works as a 1ph meter.

The meter can be powered up from any L1, L2 and L3 phase. However, for the practical application of our product, the meter shall always be connected to L1. Without L1, the entire device (meter + EVSEClosed Electric Vehicle Supply Equipment) won’t work. A configuration where L1 is not connected, but L2 and L3 is, is not valid.

Wiring Systems

Supports TT, TNS, TNC-S, and IT systems. Neutral is mandatory. In IT systems without a neutral, L2 may serve as neutral (max 230 VAC).

LCD Display

The backlit LCD shows cumulative active energy.
