Johnson Controls DCPA-1.2 Power Supply

The Johnson Controls DCPA-1.2 is a light-duty, regulated power supply designed to provide stable 24 VAC/VDC power for HVACR controllers and field devices. Built for consistency in building automation systems, this unit accepts a 120 VAC input and maintains a precise 1% temperature stability, ensuring terminal equipment receives clean power regardless of environmental fluctuations. It is rated for an operating temperature range of 32 to 130°F (0 to 54°C), making it suitable for standard mechanical rooms or control cabinets. With a 95% noncondensing relative humidity rating, the DCPA-1.2 handles moisture-prone environments where lesser power supplies might suffer from internal corrosion or shorting. The compact form factor allows for efficient integration into 24V control circuits, providing a necessary bridge between line voltage and low-voltage electronic components. For technicians requiring a reliable AC/DC power converter for intermittent or continuous duty, this unit delivers predictable results with minimal thermal dissipation.

• Ensures stable voltage output with 1% temperature stability to prevent controller reboots or communication errors.
• Provides flexible 24 VAC/VDC output suitable for a wide variety of Johnson Controls hardware and third-party sensors.
• Rugged construction rated for 95% RH noncondensing, ensuring performance in high-humidity mechanical environments.
• Fixed 120 VAC input streamlines installation within standard electrical panels and control enclosures.

Can the DCPA-1.2 be used in outdoor-rated enclosures?
Yes, provided the enclosure is properly sealed to prevent direct moisture contact, as the unit is rated for up to 95% noncondensing humidity and temperatures up to 130°F.

What happens if the input voltage fluctuates?
The DCPA-1.2 is designed with high stability ratings to maintain a consistent output voltage, protecting sensitive downstream electronic components from surges or dips.

Is this unit compatible with non-Johnson Controls equipment?
As long as the field device requires a 24 VAC or VDC supply and stays within the unit’s amperage rating, it will function as a standard industrial power supply.
