Product Description

CL1131

CL1131 is a high-performance, high-reliability electronic transformer specifically designed for applications requiring extreme safety and signal integrity. Developed by Beijing CoreLogic Communication Co., Ltd., this model features a robust encapsulated design and provides superior electrical isolation of up to 4000V AC. It is an ideal solution for power line communication (PLC), industrial control systems, and medical-grade equipment isolation.

Key Features & Advantages

      Superior 4kV Isolation: Tested at AC 4000V 1mA for 60s, ensuring the highest level of safety for sensitive circuits and operators.

Encapsulated Potting Process: The V2.0 upgrade includes a specialized epoxy resin potting process, providing excellent moisture resistance, vibration protection, and enhanced dielectric strength.

      Triple Insulated Wire (TIW): All windings (N1-N6) utilize high-quality triple-insulated wires to guarantee reliable performance under high-voltage stress.

      High-Precision Toroidal Core: Built with a P47 CUT23*11 magnetic ring for high efficiency and minimal electromagnetic interference (EMI).

      Compact Low-Profile Design: With a maximum height of only 15mm, it is perfect for space-constrained PCB layouts.

      Low Parasitic Parameters: Features a low distributed capacitance (10pF Max) and low leakage inductance (1uH Max) for high-speed signal clarity.
