The Schneider Electric EM3460 is an advanced, solid-state energy monitoring and demand controller designed to help commercial and industrial facilities reduce their electricity costs by actively managing and limiting their peak power demand.

Product Overview

The Conzerv EM3460 is a key component in any energy management strategy. Its primary function is to prevent a facility’s electrical demand from exceeding a pre-set limit (in kW or kVA), thereby avoiding costly demand charges from utility companies. It achieves this by intelligently shedding and restoring non-essential loads in a prioritized sequence.

The model number EM3460 1A0.2 RS 240AX provides specific details about the unit’s configuration:

• EM3460: Base model series for the Smart Demand Controller.

• 1A0.2: Specific hardware/firmware version.

• RS: Indicates it is equipped with a RS-485 communication port for integration with Building Management Systems (BMS) or data loggers.

• 240AX: Specifies the voltage input (240V AC) and the current transformer (CT) input type.

Key Features & Capabilities

1. Peak Demand Management:

   • Core Function: Continuously monitors total facility power and predicts future demand based on current consumption trends.

   • Load Shedding: Automatically turns off pre-programmed, non-essential loads (e.g., water heaters, AC units, exhaust fans) when the demand approaches the setpoint.

   • Load Restoration: Staggeredly restores loads when the demand threat has passed, preventing a new peak upon restoration.

2. Advanced Metering & Monitoring:

   • Measures key electrical parameters including kWh, kW/kVA Demand, V, A, PF (Power Factor), and Frequency.

   • Provides data logging capabilities for historical analysis and reporting.

3. Flexible & Intelligent Control:

   • 4 or 8 Relay Outputs: Depending on the variant, it provides multiple dry contact relays to control contactors or relays for load switching.

   • Priority Programming: Allows users to assign a priority level (1 through 8) to each connected load. Lower priority loads are shed first and restored last.

   • Multiple Control Strategies: Offers options like “Continuous Duty,” “Duty Cycle,” and “Temperature Control” for flexible load management.

4. User Interface & Communication:

   • Front Display: A backlit LCD screen provides real-time data on demand, current, voltage, and system status.

   • Keypad Interface: Allows for easy configuration of setpoints, priorities, and system parameters.

   • RS-485 Communication (as per model): Enables integration with SCADA, BMS, or energy management software using protocols like Modbus RTU.

5. Robust Design & Safety:

   • Designed for reliable operation in harsh electrical environments.

   • Typically housed in a DIN-rail mountable enclosure for easy installation in electrical panels.

Technical Specifications (Summary)

Primary Applications

The Conzerv EM3460 is ideal for any facility with significant demand charges on its utility bill, including:

• Commercial Buildings: Office buildings, shopping malls, retail stores.

• Industrial Facilities: Manufacturing plants, warehouses, workshops.

• Institutional Buildings: Schools, hospitals, government buildings.

• Hospitality Sector: Hotels and resorts.

Benefits

• Cost Savings: Directly reduces peak demand charges, leading to lower electricity bills.

• Increased Energy Awareness: Provides valuable data to identify energy waste and inefficiencies.

• Prevents Utility Penalties: Helps avoid exceeding contract demand limits set by the utility.

• Improved Load Management: Automates the control of non-critical loads without disrupting core operations.
