- Provides isolated 24 VAC output from standard 120 VAC input
- Includes integrated circuit breaker for overcurrent protection
- UL Class 2 listed for enhanced safety compliance
- Features single hub design with foot mount for secure installation
Current Sense Transformers Applications
- Industrial control panel power distribution
- HVAC system component powering
- Low voltage isolation for sensitive instrumentation
Current Sense Transformers Procurement Notes
Verify the specific model suffix to confirm the hub configuration and mounting style matches your enclosure requirements. Ensure the 75 VA rating meets the total load demand of connected devices. Confirm that the 120 VAC input voltage aligns with your facility's supply. Check for any regional certification requirements beyond UL listing before finalizing procurement.
Current Sense Transformers Selection Notes
Select this model when a 75 VA capacity is required for 24 VAC loads. The single hub design suits panels with limited knockout space compared to dual hub variants. Consider the integrated circuit breaker as a key differentiator for simplified protection schemes without external fuses. Verify physical dimensions against available panel space.
Current Sense Transformers Part Context
This component belongs to the Dwyer APT Series of AC power transformers. The series offers various VA ratings including 20, 40, 50, 96, and 150 VA options. The APT-75-1SB specifically denotes the 75 VA variant with single hub mounting. Other models in the line may differ in hub count or mounting hardware while maintaining similar electrical characteristics.
Current Sense Transformers Replacement Considerations
Direct substitutes include other Dwyer APT series models with identical 75 VA ratings but different hub configurations, such as the APT-75-1DB which features dual hubs. Cross-brand replacements must match the 120 VAC input, 24 VAC output, and 75 VA capacity while verifying physical footprint compatibility.
