Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm exact electrical ratings and physical dimensions. Ensure the procurement specification matches the required 75 VA power rating and 25 VAC center-tapped secondary configuration. Confirm compliance with relevant environmental standards such as RoHS before finalizing orders.
Selection Notes
Select this component when a 75 VA enclosed transformer with a 115 VAC primary and 25 VAC CT secondary is required. Consider the chassis mounting style and wire lead termination type for integration into existing enclosures. Verify that the 2000 Vrms isolation voltage meets system safety requirements.
Part Context
This model belongs to the Hammond 167 series of low voltage power transformers. These units are characterized by their enclosed design and chassis mounting capabilities, intended for use in industrial environments requiring reliable step-down voltage conversion from standard line voltages to lower control or filament levels.
