Multifunctional measuring instrument Selectric SMP-53A-LM96

SMP-53A-LM96 is a compact, multifunctional industrial‑grade measuring device for monitoring power grid parameters, measuring energy consumption, and integrating into dispatch and automation systems. The device is based on a high‑performance industrial microprocessor and is designed for use in distribution cabinets with limited mounting space.

The device ensures high‑precision real‑time data processing and supports monitoring of three‑phase network parameters. Thanks to the choice of form factors 96×96 or 72×72 mm, the device is ideally suited for low‑voltage cabinets, floor distribution panels, and building automation systems.

Main functions:

• Measurement of three‑phase voltage and current;
• Measurement of active, reactive, and apparent power;
• Power factor measurement;
• Grid frequency monitoring;
• Analysis of harmonics from the 2nd to the 31st;
• Accounting for active and reactive energy;
• Neutral current monitoring;
• Alarm for exceeding setpoints;
• Event log;
• Pulse output;
• Support for digital inputs and relay outputs;
• RS-485 interface with Modbus RTU support;
