ACREL Three Phase DIN Rail Multifunction Energy Meter with RS485 Modbus
Three Phase DIN Rail Multifunction Energy Meter with RS485 Modbus (ADL3000-E-A/KC & ADL3000-E-B/KC) is a three-phase CT-connected energy meter for electrical measurement and power management. It measures key electrical parameters, active and reactive energy, harmonic content and supports RS485 Modbus-RTU communication. Its DIN rail format makes it suitable for integration into electrical distribution, energy monitoring and SCADA systems.
Key Differences: -E-A vs -E-B
Current Ratings:
Variant models generally map to either direct access configurations (e.g., 3 × 10(80)A) or Current Transformer (CT) operated configurations (e.g., 3 × 1(6)A or 5A CT input).
The -E-B variants (such as ADL3000-E-B/KC) are frequently highlighted with UL certification for North America or specific solar inverter and SCADA applications using 5A CT connections.
The Three Phase DIN Rail Multifunction Energy Meter with RS485 Modbus provides electrical measurement and energy management for three-phase systems. The CT-connected design allows the meter to measure circuits using current transformers rather than direct high-current connection.
The meter measures electrical parameters including voltage, current, active power, reactive power, apparent power, power factor and frequency. It also supports active and reactive energy measurement and harmonic analysis.
For system integration, the meter provides an RS485 communication interface using Modbus-RTU. This allows measured data to be collected by compatible monitoring systems, SCADA platforms and energy management systems.
How it works
- The meter connects to a three-phase, four-wire system through current transformers.
- It measures the voltage and CT-derived current signals from the three phases.
- The meter calculates electrical parameters such as power, power factor, frequency and energy.
- Measured information can be viewed locally and transferred through RS485 using Modbus-RTU.
- Harmonic measurement can be used to monitor harmonic content within the electrical system.
