Johnson Controls PSM19A24DAS Power Supply

Johnson Controls PSM19A24DAS Power Supply

The Johnson Controls PSM19A24DAS is a heavy-duty linear DC power supply engineered specifically for technical professionals managing building automation and HVAC control systems. This track-mount isolated power supply accepts a standard 120 VAC input and delivers a highly stable, adjustable DC output ranging from 1.5 to 28 VDC. For contractors working with sensitive microprocessors or control boards, the isolated design prevents electrical noise and ground loops from compromising downstream equipment performance. The 300 mA output current capacity makes it an ideal solution for low-draw applications requiring precision voltage regulation. Built on a physical MT212 track mount for fast installation into control cabinets, the unit includes a physical 2-position on/off switch and an integrated LED status indicator for immediate field diagnostics. Whether you are powering 24 VDC actuators or custom sensor arrays, this Class 2 power supply provides the reliable, full-wave rectified 120V to 24V conversion demanded by rigid industrial standards.

Key Benefits
  • Precision Voltage Control: Fully adjustable 1.5 to 28 VDC output allows for fine-tuning based on specific controller requirements.
  • Enhanced Circuit Protection: Features internal electrical and thermal protection with automatic reset to safeguard your HVAC control power supply.
  • Versatile Mounting: Designed for efficiency with 2.75" and 4.00" track mounting options, fitting industry-standard control panels perfectly.
  • Isolated Linear Output: The isolated DC power supply architecture minimizes interference, ensuring clean power for sensitive electronics.
  • Field Readiness: Equipped with a dedicated 2-position on/off switch for safe servicing and an LED for rapid power status verification.
Common Questions

Can I use this to replace a standard 24VAC transformer?
Yes, provided your end devices require DC voltage. This unit converts 120VAC line voltage into a regulated DC output, which is often required for high-end thermostats and digital controllers that cannot run on raw AC power.

Does this unit require a specific mounting enclosure?
The PSM19A24DAS is open-board and intended for installation within a UL-approved control cabinet using the provided MT212 track. Its compact 1.6" x 2.7" x 4" footprint is optimized for high-density panel layouts.

Is the output current enough for multiple actuators?
With a maximum output of 300 mA, this supply is intended for low-power control circuits. Always calculate the total milliamperage draw of your connected sensors or actuators to ensure it remains below the 300 mA threshold.
