E7400.0010

The Littelfuse E7400.0010 Phase Comparator Unit is a critical component for ensuring the integrity and efficiency of industrial power systems. Engineered by Littelfuse, a trusted leader in circuit protection and power control, this unit provides precise phase angle measurement and monitoring, essential for a wide range of demanding applications. Designed for robust performance, the E7400.0010 operates reliably across a broad input voltage range, accommodating both AC (65-265 Vac, 30 VA) and DC (80-275 Vdc, 25 W) power sources. Its advanced AC measurement capabilities include True RMS and DFT (Discrete Fourier Transform) analysis, capturing peak values with 32 samples per cycle, and accurately determining the positive and negative sequences of the fundamental frequency. This comprehensive data acquisition ensures a deep understanding of system dynamics. Key features of the Littelfuse E7400.0010 include: * **Versatile Power Input:** Supports 65-265 Vac (30 VA) and 80-275 Vdc (25 W) for flexible integration. * **Advanced AC Measurements:** Utilizes True RMS and DFT, capturing peak values and fundamental sequences for detailed analysis. * **Fast Response Times:** Features a power-up time of 800 ms at 120 VAC and a minimum ride-through time of 100 ms, ensuring continuous operation. * **Multiple Output Contacts:** Equipped with three Form C output contacts for versatile control and signaling. * **Extensive Communication Options:** Standard TIA-232 interface, with optional TIA-485, DeviceNet™, and Ethernet for seamless integration into SCADA and automation networks. * **Programmable Analog Output:** Includes a 4-20 mA analog output, which is fully programmable for integration with other monitoring systems. * **Durable Construction:** Features a standard conformally coated design for enhanced protection in harsh industrial environments. * **Extended Warranty:** Backed by a 10-year warranty, reflecting Littelfuse's commitment to quality and reliability. The E7400.0010 is instrumental in applications such as overload protection (49, 51), phase sequence monitoring (46), unbalance detection (46), phase loss detection (46), definite-time and inverse-time overcurrent protection (50, 51), and ground fault detection (50G/N, 51G/N). It also supports RTD/PTC temperature monitoring (49) and is a core component in standard feeder protection schemes. Installation is flexible, with standard panel mounting for the control unit and DIN or surface mounting options for the current input module. The unit requires Phase Current Transformers (CTs) for phase current detection and can utilize a zero-sequence current transformer for ground-fault current detection, available in 5-A and 30-A primary ratings. Accessories like the MPU-32-SMK converter kit enable surface mounting of the control unit. With approvals including CSA certification, CE, C-Tick (Australian), and UL Recognition, the Littelfuse E7400.0010 meets stringent international standards, providing peace of mind for critical industrial operations. Its robust design, advanced features, and comprehensive support make it an indispensable tool for maintaining system stability, preventing equipment damage, and optimizing operational efficiency in power generation, distribution, and industrial automation.
