Overview
The Hammond Manufacturing 165M75 is a dry-type transformer designed for general-purpose applications. It features a 225VA power rating with a primary voltage of 115V and a secondary configuration providing 75V center-tapped (CT). The unit delivers a current capacity of 3A on the secondary side. Constructed as a standard dry transformer, it operates at 60Hz and utilizes Class A insulation. The component is engineered for chassis or panel mounting, offering a compact form factor suitable for integration into various electronic systems requiring reliable voltage transformation.
Feature Summary
- Provides 225VA power handling capability for stable electrical operation
- Features a 115V primary input with a 75V center-tapped secondary output
- Utilizes Class A insulation for thermal management in dry-type construction
- Designed for secure chassis or panel mounting in industrial environments
Applications
- General-purpose voltage transformation in electronic equipment
- Power supply units requiring 75V center-tapped outputs
- Industrial control panels and machinery
- Audio amplifier power stages
- Test and measurement instrument power systems
Procurement Notes
Verify the specific voltage configuration and physical mounting requirements against your system design before ordering. Confirm that the 225VA rating and 3A current capacity meet the load demands of your application. Ensure compatibility with the 115V primary supply voltage available in your operational environment. Check local shipping restrictions regarding product size or weight if applicable to your region.
Selection Notes
Select this model when a 225VA dry transformer with a 75V CT secondary is required. Compare against other Hammond models like the 165L50 for different VA ratings or voltages. Consider the physical dimensions and mounting style to ensure fit within the enclosure. Evaluate the operating frequency and insulation class to match environmental conditions.
Part Context
This component belongs to the series of dry transformers manufactured by Hammond Manufacturing. These transformers are widely used in industrial and commercial applications for stepping down or isolating voltages. The 165M75 specifically addresses needs for moderate power levels with a center-tapped secondary, common in rectifier circuits and audio applications.
Replacement Considerations
For direct replacements, consider Hammond part numbers with identical VA ratings and voltage configurations, such as those in the 165 series. Verify that any substitute matches the 75V CT secondary specification and 115V primary requirement. Ensure physical dimensions and mounting hole patterns are compatible to avoid enclosure modifications.
