Functional Devices PSM19A24DAS Power Supply
The Functional Devices PSM19A24DAS is a professional-grade, track mount power supply engineered for contractors requiring a stable 120VAC to 24VDC conversion in building automation and HVAC control systems. This isolated linear power supply provides an adjustable output range of 1.5 to 28 VDC, making it highly versatile for various low-voltage field devices. Built with a linear transformer design, it offers significantly lower ripple and noise compared to switching alternatives, which is critical for sensitive HVACR equipment and electronic controllers. The unit features built-in electrical and thermal overload protection with an auto-reset function to prevent field failures during transient spikes. A dedicated 2-position ON/OFF switch and a power status LED allow for immediate visual diagnostics and safe maintenance. The inclusion of the MT212-4 mounting track ensures a standard 4-inch footprint for seamless integration into existing control panels and electrical enclosures.
Key Benefits:- Provides a stable 24 VDC output with adjustable precision from 1.5 to 28 VDC for customized HVAC voltage regulation.
- Features high-tier isolated power architecture to protect downstream controllers from input line noise and 120V power supply fluctuations.
- Includes an integrated auto-reset thermal protection mechanism to safeguard the circuit board against overheating and short circuits.
- Comes standard with MT212-4 track mount hardware for rapid installation in industrial control cabinets.
- Equipped with a primary ON/OFF switch and LED indicator for simplified HVAC troubleshooting and power verification.
Can I use this power supply for sensitive digital controllers?
Yes, the linear power supply design is specifically intended for applications where low electrical noise is required, providing a cleaner signal than most switching power supplies.
What happens if the unit overloads?
The PSM19A24DAS is equipped with internal overload protection. If the current or temperature exceeds safe limits, the unit will trip and then automatically reset once the fault condition is cleared and the unit cools down.
Is the output voltage fixed at 24V?
No, while commonly used as a 24VDC power supply, the output is fully adjustable between 1.5 and 28 VDC using the on-board potentiometer to meet specific HVAC component requirements.
