Functional Devices PSP24DA Power Supply

The Functional Devices PSP24DA is a rugged, regulated power supply designed for critical BAS and HVAC control applications where precise DC voltage is non-negotiable. This 24VAC to 24VDC converter handles high-demand peripherals by providing a stable 1.5 Amp output from a standard 24VAC input. Engineered for DIN rail mounting, the PSP24DA features an adjustable output ranging from 1.5VDC to 28VDC, allowing technicians to fine-tune voltage levels to compensate for long wire runs or sensitive field controllers. The inclusion of a 10 Amp P1 (Auto-Reset) fuse ensures circuit protection during overcurrent events, eliminating the need for constant fuse replacements in the field. This unit is essential for powering low voltage control circuits, modular controllers, and auxiliary sensors that require clean DC power without the ripple issues common in lower-tier power modules. For contractors installing sophisticated automation hardware, the PSP24DA provides the reliability needed for 24/7 operation in commercial environments.

• Adjustable DC Output: Field-adjustable potentiometer allows for a precise 1.5 to 28VDC range to match specific load requirements.
• Automatic Circuit Protection: Features a 10 Amp internal auto-reset fuse, preserving the integrity of the stepped-down power supply.
• Universal DIN Rail Mounting: Comes equipped with standard DIN rail clips for fast, secure installation in control cabinets.
• LED Diagnostic Indicator: Integrated status light provides immediate visual confirmation of power output for faster troubleshooting.
• High Current Capacity: Delivers a consistent 1.5 Amp output, supporting multiple sensors or a single high-draw controller.

What is the maximum input voltage for the PSP24DA?
This module is designed to accept a nominal 24VAC input, typically sourced from a Class 2 transformer, making it compatible with most standard HVAC control systems.

Can I use this to power 12VDC devices?
Yes, because the output is adjustable down to 1.5VDC, you can tune the potentiometer to deliver a steady 12VDC for specific relays or specialty hardware.

How does the auto-resetting fuse behave during a short?
The internal P1 fuse will trip and open the circuit upon detecting an overload. Once the fault is cleared and the component cools, it resets automatically, minimizing downtime and maintenance calls.
