Single Phase Multifunction Meter SFM236 Series - Reliable Power Monitoring from China Suppliers and Factory
Calibrated for exceptional accuracy, the SFM236 series meter captures a complete set of critical single-phase power parameters to support comprehensive load analysis and energy auditing:
- Voltage: RMS line voltage (compatible with standard system voltages such as 100 V, 120 V, 220 V, 230 V, 240 V)
- Current: RMS load current (configurable for direct measurement or CT-connected applications with 1 A/5 A secondary ratings)
- Power: Active power (real power consumed/supplied), reactive power (power stored in inductive/capacitive loads), and apparent power
- Frequency: Grid frequency fluctuations (typically 50 Hz/60 Hz, with precise tracking of variations)
- Energy: Cumulative import energy (power drawn from the grid) and export energy (power fed back to the grid, suitable for distributed generation systems like rooftop solar)
Designed to meet diverse on-site monitoring needs, the SFM236 series meter supports two flexible operational modes:
The meter is equipped with an on-board digital display that presents real-time readings of all measured parameters. This allows field technicians and facility managers to perform quick spot checks, verify system performance, and troubleshoot issues without relying on external equipment.
Beyond local monitoring, the meter's detection data can be seamlessly transmitted to industrial control devices (including PLCs, RTUs, and energy management controllers) and host computers via industry-standard communication protocols. This integration enables the construction of a unified, centralized measurement and control system, supporting remote data logging, energy consumption trend analysis, load profiling, and automated power management.
