The Micrologic 5.0P is a high-performance control unit that provides advanced protection, monitoring, and measurement for electrical circuits in low voltage power distribution systems. It is engineered for applications where detailed knowledge of power consumption and electrical parameters is crucial for energy management and operational efficiency.
Key Features & Core Functionality
-
Comprehensive Protection:
-
Long-Time Delay:Â Protects against sustained overloads.
-
Short-Time Delay:Â Protects against medium-level short-circuit currents.
-
Instantaneous:Â Protects against high-level short-circuit currents.
-
Ground-Fault Protection (5.0P):Â This is the defining feature. It detects current leakage to ground, which is critical for protecting equipment and personnel from ground faults. The “G” setting is adjustable.
-
-
Power & Energy Monitoring (The “P” in 5.0P):
-
Measurement:Â Provides real-time measurement of key electrical parameters, including:
-
Current (A)
-
Voltage (V)
-
Power (kW, kVA)
-
Power Factor (PF)
-
Frequency (Hz)
-
Energy (kWh)
-
-
Display:Â Features a clear, backlit LCD screen to display all measured values, setpoints, and alarm information.
-
-
Communication Ready:
-
Comes equipped with a built-in communication port (typically for FDM121 display or a communication module).
-
Can be easily integrated into Building Management Systems (BMS) or SCADA systems using protocols like Modbus, Profibus, or Ethernet via Schneider Electric’s communication boards (e.g., COM-100, COM-150).
-
-
Event Recording & Logging:
-
Records the last several trips with detailed information (date, time, current value, type of fault), which is invaluable for troubleshooting and root cause analysis.
-
-
Load Shedding & Control:
-
Can be programmed to issue alarms or trip commands based on power thresholds, enabling demand control and load shedding to avoid peak demand charges.
-
