Energy meter

Product catalog summary

Product Description: The document describes the PEM series energy meters, which measure energy and power values. These meters are suitable for billing purposes when they meet the Measurement Instrument Directive (MID) conformity mark requirements.

Standards: The energy meters comply with accuracy class B according to EN 50470-3 and accuracy class 1 according to IEC 62053-21.

Device Features: Key features include a Modbus RTU interface, MID approval, a 7-digit display, automatic bus transmission rate and parity recognition, optional lead sealing, resettable partial readings, and additional measurements such as current, voltage, power, and cos(phi). The meters are designed for DIN rail mounting.

Technical Data:

ALD1: Operates at AC 230 V, 50 Hz with a tolerance of -20%/+15%. Reference current is 5 A, maximum current is 32 A, and power consumption is 0.4 W. The counting range is from 00,000.00 to 999,999.9 with 2000 impulses per kWh.
ALE3: Operates at 3 x AC 230/400 V, 50 Hz with similar tolerance. Reference current is 10 A, maximum current is 65 A, and power consumption is 0.4 W per phase. The counting range is similar to ALD1 with 1000 impulses per kWh.
AWD3: Operates at 3 x AC 230/400 V, 50 Hz with transformer measurement from 5 to 1500 A. Reference current is 5 A, maximum current is 6 A, and power consumption is 0.4 W per phase. The counting range extends to 9,999,999 with similar display features.

Ordering Information: The document lists various energy meters and accessories with their respective article numbers, including sealable covers for different models.

Wiring Diagrams: Detailed wiring diagrams for ALD1, ALE3, and AWD3 models are provided, illustrating connections for Modbus RTU interfaces and energy/pulse counters.

Additional Information: The document includes dimension diagrams and notes on the connection of secondary current transformers, emphasizing that they must not be earthed.

Energy meter Energy meter AWD3 Product description Along with numerous measuring values, all PEM series devices can measure energy and power values. If, however, a measuring point is used for billing purposes, special requirements must to be met (subject to obligatory calibration). Energy meters with the Measurement Instrument Directive (MID) conformity mark meet these requirements. The energy meters have been developed in accordance with the following standards: Accuracy class B acc. to EN 50470-3, accuracy class 1 acc. to IEC 62053-21.
