Panel-mounted | Digital 380V power network analyzer three-phase | with current transformers (CT) 3x250A | RS485 Modbus RTU

Technical Specifications
Supply Voltage (Un): 85V–240V AC

Current Measurement Range: 10A–250A (with included transformers)

Voltage Measurement Range: 5V–330V AC (L-N)

Accuracy: Voltage/Current: ±0.5%; Active Power: ±1%; Reactive Power: ±2%

Communication Protocol: RS485 Modbus RTU (1200 – 38400 bps)

Connection: 3-phase, 4-wire (3P4W)

Protection Class: IP41 (front panel), IP20 (casing)

Mounting: Panel door (91x91 mm cutout)

Operating Temperature: -20°C to +55°C

Key Features and Functions
Comprehensive Measurement: Monitors voltage, current, cosϕ, active, reactive, and apparent power for each phase individually.

Energy Metering: Measures imported/exported active energy and inductive/capacitive reactive energy.

Data Logging: Records events (over/under voltage, current imbalance, THD-I distortion) and minimum/maximum values.

Control: Features one programmable relay output for automatic load shedding or alarms.

Interface: Bright 4x4 digit LED display and an intuitive, password-protected menu.

Application
For the Electrician: Easy installation thanks to plug-in terminal connectors and included current transformers. No need to worry about component compatibility – everything is ready for quick installation into a standard 91x91 mm panel door cutout.

For the Engineer and Energy Specialist: For industrial energy efficiency analysis. The RS485 connection allows integration into a Building Management System (BMS). THD-I (Total Harmonic Distortion) monitoring helps identify network interference that could damage sensitive equipment.

For the Home User: If you want to monitor your home solar power generation, heat pump consumption, or general grid quality in detail, this analyzer provides significantly more data than a standard meter. The relay output allows you to create scenarios, such as turning off non-essential appliances when a certain power limit is reached.

Pros & Cons
Pros:

All-in-one: Current transformers are included in the set.

Remote Monitoring: Modbus RTU support for data transmission to a computer or controller.

Diagnostics: Records not only consumption but also grid quality parameters (harmonics, voltage sags).

Security: Password-protected menu prevents unauthorized changes to settings.

Cons:

Mounting Type: Designed for panel door mounting, not for DIN rail.
