PRO PM335

 

PRO EM235

The PRO series is SATEC’s newest, cost-effective line of  ultra-compact power meters for advanced power applications.
 

The Digital Substation

Today's world of power metering and telemetry requires full connectivity, relying on advanced communication protocols and enveloping cyber-security. Featuring a comprehensive communication platform, including Dual Port Ethernet, IEC 61850 communication protocol, DNP3 and IEC 60870-5101/104 the PRO meter is designed to answer the needs of the modern digital substation.
 

DC metering and Renewable energy

Direct Current systems are on the rise in applications such as solar farms, energy storage and data centers. The efficiency of these systems is crucial and the metering of the actual DC circuits before inversion to AC gives an important health-check of these facilities. The PRO series introduces rare capabilities and precision in this new field of DC metering.
 

Industrial Energy Management

A variety of attachable digital I/O modules, combined with the measured electrical parameters and the ability to program the meters with PLC logic setpoints enables versatile control functionalities. This way a meter does not only monitor the energy consumed in an industrial process but also measures its efficiency, alerting of irregularities and taking needed action such as shutting down power or a critically failing process via relay outputs.
With AC and DC metering combined it is an extremely powerful tool for a wide variety of energy-consuming industrial processes.
