Three-phase electric energy meter EM619002

DIN railRS-485programmable

Product overview
EM619002 is a DIN-rail DC energy meter for measurement and monitoring of DC systems. It records voltage, current, power and energy, supports bidirectional active energy measurement and multi-tariff recording. Data is available via RS485 (Modbus RTU/DLT645). Typical applications: DC panels, photovoltaic strings, battery energy storage, EV charging piles and telecom base stations.

Applications

• Photovoltaic (solar) string monitoring
• Battery energy storage systems (BESS)
• EV charging stations
• Telecom base stations and data centers

Other models in EM series
Series includes EM613001 (40–400V), EM613005 (8–48V), EM619001, EM619002 (5–1000V) and MID-compliant shunt meters EM619025, EM619026, EM619027.
