This transformer may not be suitable for high-voltage applications exceeding its rated insulation levels or for environments with extreme electromagnetic interference that could compromise signal integrity. It is also not intended for use in circuits where the primary current exceeds the specified measurement range of the device.
Key specifications
Type: Single-phase split-core current transformer
Design: Openable core for non-invasive installation
Application: Current measurement and monitoring
Compatibility: Suitable for existing electrical cabling
To use the FF TO-1250, simply open the split-core housing, place it around the conductor carrying the primary current, and securely snap the core shut. Ensure the orientation follows the manufacturer's markings for proper polarity. Connect the secondary output terminals to your measuring device, such as a power meter or data logger, using appropriate wiring to ensure accurate signal transmission.
What to consider before purchase
Verify the primary current range of your circuit matches the transformer specifications
Ensure there is sufficient physical space around the cable for the split-core housing
Check the compatibility of the secondary output with your existing monitoring equipment
Usage recommendations: Always ensure the circuit is de-energized during the physical installation of the transformer for safety. Periodically inspect the snap-lock mechanism to ensure the core remains tightly closed for optimal measurement accuracy.
