Circuit-level power meter
Power Meter
A CT current node that clamps onto circuits in the panel and reports over RS485 Modbus into Power Management. The gateway also reads 3-phase Modbus meters on the main board.
Power Management- 30 A split-core CT — no wires cut
- RS485 Modbus RTU, many nodes on one bus
- Reads 3-phase Modbus meters (e.g. Schneider PM2230) via the gateway
- Data lands on the Power Management dashboard immediately
Capabilities
No power cut to install
A 30 A split-core CT clamps onto existing circuits in the panel.
Many nodes, one cable
RS485 Modbus RTU with 30 addresses (170–199) on a single bus.
Calibratable
Tune readings to the site over the serial port.
Reads the main meter
The gateway reads 3-phase Modbus meters such as Schneider PM2230 — voltage, current, power, kWh.
Straight into Power Management
Each circuit appears on the dashboard in its site › building › floor › room place.
Clear about what it measures
CT nodes measure current; power is computed from configured voltage and PF. Use the main meter for billing-grade values.
Connections
The device reads the field, drives equipment, and sends data to the cloud.
