Engineering Advantages

  • Precision Phase Alignment: The 1402-LS51 utilizes 1-degree phase step resolution and 0.05% voltage steps. This granularity allows engineers to synchronize independent power sources with surgical precision, preventing torque spikes and equipment stress during transition.

  • High-Voltage Safety Margin: With a 2500V RMS dielectric withstand rating, the module provides a robust barrier between power circuits and sensitive control backplanes. This protects your logic hardware from catastrophic failure during line surges.

  • Exceptional Thermal Resilience: The open equipment design facilitates natural convection cooling, allowing the module to maintain steady-state accuracy across a full 0 to 60°C operating range without derating.

  • Low Burden Integration: The current input burden of only 0.05 VA ensures that the module monitors the system without parasitic interference, maintaining the accuracy of the overall power loop.

FAQs

  • What chassis is required for the 1402-LS51?

    This module installs specifically into a standard 1771 I/O chassis. Note that it requires two consecutive slots due to its solid-state architecture and cooling requirements.

  • How does the module handle high inrush currents?

    The 1402-LS51 manages a massive 200A RMS for up to one second. This capability ensures the module survives the transient spikes often encountered during large motor starts or grid fluctuations.

  • Is this unit a refurbished or surplus item?

    No. We guarantee that this 1402-LS51 is 100% Brand New. It arrives in original factory condition, ensuring all dielectric and frequency tolerances meet the manufacturer's strict specifications.

  • Does the module support 50Hz and 60Hz systems?

    Yes. The frequency range spans from 40 to 100 Hz, making it compatible with all global industrial power standards, including standard 50Hz and 60Hz grids.
