Energy Audit & SCADA
RS485 Modbus integration feeds live DC energy data into SCADA systems for trend analysis.
FAQ
Frequently Asked Questions
Three options: Shunt-based (direct in-line), Hall Effect Sensor (non-contact), and Split Core Hall Effect (clamp-on). The choice depends on your installation constraints and whether you can break the circuit for installation.
The device communicates via 2-wire optically isolated RS-485 using Modbus RTU slave protocol. It integrates with SCADA systems, PLCs, or Spaceage's Remote Energy Monitoring Solution for centralised energy tracking.
The meter achieves ±1% of range accuracy for voltage (20–70V DC), current (0–99.9A DC), and cumulative energy. Resolution is 2 decimal places for voltage and energy, and 1 decimal place for current.
