Overview
The Sifam Tinsley Instrumentation Inc. model 19RL 501 is a current sense transformer designed for non-invasive AC current measurement. It features a primary current rating of 500 A and a secondary output of 500:5 ratio, supporting frequencies from 50 Hz to 400 Hz. The unit utilizes a free-hanging in-line mounting configuration with a solid core design. This component belongs to the Omega series, providing reliable electrical isolation and signal conversion for power monitoring systems without requiring conductor disconnection.
Feature Summary
- Non-invasive solid core construction enables current sensing without breaking the primary circuit
- Free-hanging in-line mounting provides flexible installation options for various panel layouts
- Operates within a frequency range of 50 Hz to 400 Hz for versatile power system compatibility
Applications
- Power monitoring applications requiring high accuracy and minimum phase angle error
- Industrial equipment current sensing where non-invasive measurement is required
- Electrical distribution panels utilizing free-hanging transformer configurations
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm the 500 A primary rating and 500:5 secondary ratio. Ensure the application environment supports the specified 50 Hz to 400 Hz frequency range. Confirm that the free-hanging in-line mechanical form factor aligns with the intended installation space and mounting requirements before finalizing procurement.
Selection Notes
Select this component when a non-invasive solution is necessary for measuring currents up to 500 A. The 500:5 secondary ratio is suitable for standard metering inputs. Consider the 50-400 Hz operational bandwidth to ensure compatibility with the source frequency. The in-line design requires adequate clearance for the solid core assembly during installation.
Part Context
This transformer is part of the Omega series by Sifam Tinsley, which specializes in split-core and solid-core current transformers. The 19RL designation indicates a specific variant within the ANSI Metering Class lineup, focusing on efficient current measurement capabilities for industrial and commercial power distribution networks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing metering infrastructure before considering alternative models.
