Key Features
• For single-, split- and 3-phase applications.
• Measures Active (W), Reactive (VAr) and Apparent (VA) power.
• Displays electrical parameters on large, backlit LCD display.
• Features two independent opto-isolated digital outputs plus one analog 4-20mA output.
• Includes MODBUS® RTU communication as standard.
• Provides clear indication of electrical circuit performance.
• User-programmable scale and custom alarm messages display critical parameters and immediately alerts operators
when a parameter is out of range.
• Programmable Current Transformer (CT) and Potential Transformer (PT) ratios.
