FOTEK LCR-40 Solid State Relays Three-Phase Power Regulator with Enhanced Heat Sink High Surge Voltage Sustenance

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Three-Phase Power Regulation: The FOTEK LCR-40 is designed to manage and regulate three-phase power with a contact and load current rating of 40A, ensuring stable operation in high-demand environments.
  • Enhanced Safety & Performance: Equipped with an advanced heat sink and surge voltage sustenance capabilities, it safeguards against overcurrent and short circuits while maintaining optimal thermal efficiency.

Key features

  • 1. Enhanced Heat Sink and Corrosion-Resistant Construction

    • With a robust aluminum heat sink and corrosion-resistant casing, the FOTEK LCR-40 ensures sustained performance under high surge voltages and prolonged operation. This design outperforms standard relays in harsh industrial environments, reducing overheating risks by up to 30%*.

  • 2. User-Friendly Digital Interface with Programmable Controls

    • With a clear digital display and programmable "SET" button, you can easily monitor real-time voltage/current data and customize settings for precise power regulation. This interactive design simplifies setup compared to non-programmable legacy relays.

  • 3. High-Capacity Power Handling for Industrial Demands

    • Supporting a 40A load current and a wide voltage range (180-440VAC), the LCR-40 handles heavy-duty applications 20% more efficiently than conventional relays*. Ideal for three-phase systems in factories or commercial facilities.

  • 4. Transparent Front Panel for Real-Time Monitoring

    • The transparent front panel allows direct visibility of internal components like fuses and wiring, enabling quick troubleshooting and maintenance without disassembly. This feature reduces downtime by up to 15% compared to opaque models*.

  • 5. RoHS Compliance for Eco-Friendly and Safe Operation

    • Certified to RoHS standards, the LOTEK LCR-40 uses environmentally responsible materials and ensures safety compliance for industrial use. This meets stricter regulatory requirements than non-certified alternatives.
