Procurement Notes

Verify that the specific terminal type matches the system requirements, as this model supports both quick connects and solder lugs. Confirm the primary voltage setting aligns with the available line voltage (115V or 230V) before installation. Ensure the chassis mounting holes correspond to the physical dimensions provided in the official datasheet. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this transformer when a 56 VA capacity is required for applications needing a 10 VCT output. The dual primary winding capability makes it suitable for global deployment across different mains voltage standards. Consider the chassis mount style and terminal options during mechanical integration planning. Verify thermal management requirements against the maximum operating temperature limit of +105°C.
