SCHNEIDER LC1-D38M7 Actuator module

1. Product Detailed Description

A Schneider Electric Power Timer is an electrical device designed to measure, record, and display electrical parameters such as voltage, current, power (active, reactive, apparent), energy (kWh, kVArh), power factor, and frequency. It often includes specific timing functions, such as recording power consumption over set intervals, event logging, and providing time-based control or alarms. These devices are typically DIN rail mountable and are used to provide detailed insights into energy usage patterns and power quality over time. They are integral components in energy management systems, helping users understand when and how energy is consumed.

2. Product Parameters (Typical - Varies by Model)

• Voltage Measurement: AC, typically up to 600V or higher depending on the model and current transformer (CT) configuration (e.g., 600V AC, 1000V AC).

• Current Measurement: AC, wide range, often up to 5A direct or higher via external CTs (e.g., 5A direct, 100A/5A CT ratio).

• Power Measurement: Active (kW), Reactive (kVAr), Apparent (kVA).

• Energy Measurement: Active (kWh), Reactive (kVArh), often with peak demand recording (kW).

• Power Factor: Displayed and often recorded.

• Frequency: Typically 50/60 Hz.

• Accuracy Class: Often Class 0.5 or 1 for energy measurement.

• Communication Protocols: Ethernet (Modbus TCP/IP), RS485 (Modbus RTU), often optional protocols like BACnet IP/MS/TP, SNMP.

• Timing Functions: Interval logging (e.g., 15-minute intervals), event timestamping, alarm time recording.

• Display: LED or LCD display showing real-time values and historical data.

• Inputs/Outputs: Potential for alarm relays, digital inputs for external events.

• Operating Temperature: Typically -10°C to +55°C.

• Storage Temperature: Wider range, e.g., -25°C to +70°C.

• Power Supply: Often 85-265 VAC or 100-300 VDC.

3. Product Advantages

• Comprehensive Power Monitoring: Provides detailed insight into all key electrical parameters.

• Energy Cost Reduction: Identifies peak usage times and inefficient operations, enabling targeted energy-saving measures.

• Power Quality Analysis: Helps detect issues like harmonics, voltage sags/swells, and unbalance that can affect equipment and efficiency.

• Fault Detection and Diagnostics: Records events and alarms, aiding in troubleshooting and preventing downtime.

• Integration Capability: Communicates via standard protocols (Modbus, BACnet) for easy integration into existing SCADA, BMS, or energy management systems.

• Data Logging and Reporting: Stores historical data for analysis, reporting, and compliance.

• Space-Saving Design: DIN rail mountable, ideal for panel installations.

• User-Friendly Interface: Typically features an intuitive display and navigation for easy configuration and viewing of data.

4. Precautions

• Correct Wiring: Ensure proper connection to phase and neutral/ground according to the installation manual. Incorrect wiring can lead to inaccurate measurements or damage the device.

• Current Transformer (CT) Installation: If using CTs, ensure they are correctly sized, installed (observe polarity), and terminated. Never open the CT secondary circuit while energized.

• Power Supply: Verify the power supply voltage matches the device requirements before applying power.

• Electrical Safety: Observe all electrical safety precautions when installing or servicing the device. De-energize circuits before working on them.

• Environmental Conditions: Install the device in an environment within its specified operating temperature and humidity limits. Protect from direct sunlight, excessive dust, and moisture.

• Communication Setup: Configure communication settings (IP address, baud rate, etc.) correctly to ensure connectivity with the host system.

• Firmware Updates: Follow Schneider Electric’s guidelines if updating firmware to avoid issues.

5. Product Applications

• Commercial Buildings: Monitoring main feeders, subpanels, HVAC systems (chillers, pumps, fans), lighting, and tenant metering for energy management and cost allocation.

• Industrial Facilities: Tracking energy usage of production lines, motors, conveyors, and process equipment in factories, plants, and warehouses.

• Data Centers: Monitoring power distribution units (PDUs), UPS systems, and cooling equipment for efficiency and capacity planning.

• Utilities: Substation monitoring, distribution network analysis, and load profiling.

• Water and Wastewater Treatment Plants: Monitoring pumps, blowers, and motors for energy efficiency and operational optimization.

• Hospitals and Healthcare: Ensuring power quality and monitoring energy consumption in critical care areas, operating rooms, and building systems.

• Energy Audits and Management: As key sensors in energy monitoring systems to identify waste and implement conservation strategies.
