The unit supports a maximum output current of 15A, ensuring reliable operation for connected instrumentation. Its compact physical dimensions include an overall height of approximately 2-19/64 inches and a width of 1-15/16 inches, facilitating integration into standard control panels.

Feature Summary

• Converts 24 VAC input to a regulated DC power source suitable for sensitive electronic components
• Features an adjustable output voltage range allowing customization between 1.5 and 27 VDC
• Designed specifically for powering transmitters with 4 to 20 mA output signals

Applications

• Powering transmitters with 4 to 20 mA outputs in building automation systems
• Providing regulated DC power for industrial and commercial control applications
• Integration into HVAC control panels requiring stable low-voltage DC sources

Procurement Notes

Verify the specific part number suffix against official Dwyer documentation to ensure compatibility with your system requirements. Confirm that the 15A current rating meets the load demands of all connected devices. Check for any regional certification marks required for installation in your facility. Ensure the input voltage matches the available 24 VAC supply before procurement.

Selection Notes

Select this model when a regulated DC source is needed for 4-20 mA transmitters in building automation environments. Consider the adjustable voltage range if precise calibration is required for specific sensor types. Evaluate the 15A capacity against total system load to prevent overload. Compare physical dimensions against panel space constraints to ensure proper fit during installation.

Part Context

The BPS-015 belongs to Dwyer Instruments' line of low-cost DC power supplies intended for building automation. It serves as a critical interface component, transforming AC mains-derived voltage into stable DC for field instruments. This series is commonly specified in commercial HVAC and facility management systems where reliable transmitter power is essential for accurate data acquisition and control.

Replacement Considerations

Consult official Dwyer cross-reference lists for verified substitutes. Generic replacements may lack the specific regulatory compliance or mounting specifications required for existing installations. Verify that any alternative unit maintains the same input/output characteristics and physical footprint to ensure seamless integration without modifying existing wiring or enclosures.
