Johnson Controls DCP-1.5-W Power Supply

The Johnson Controls DCP-1.5-W is a high-performance, regulated DC power supply engineered for demanding HVACR and building automation environments. Designed to convert a 24 Vac input into a steady 24 Vdc output, this unit provides a consistent 1.5 Amp current rating to ensure the reliable operation of sensitive controllers and sensors. This model, often cited as the DCP1.5W, features an adjustable output range from 1.5V to 27 Vdc, allowing for precise field tuning with a simple screwdriver. Built for durability, it operates efficiently within a 32?F to 130?F temperature range and includes integrated overcurrent protection via a 3-amp fuse (GF-3) to safeguard downstream components. The compact snap-track mounting design and pressure-plate screw terminals facilitate rapid installation in standard control panels, making it a staple for contractors requiring a 24VAC to 24VDC converter that maintains tight 1.5% regulation under full load.

Key Benefits

• High Precision Regulation: Maintains a 1.5% regulation rate at full rated current, ensuring stable voltage for sensitive electronic HVAC controls.
• Field Adjustable Output: Versatile voltage settings from 1.5V to 27 Vdc allow the DCP-1.5-W to adapt to specific peripheral requirements.
• Simplified Installation: Features a rugged snap-track mount and screw terminals with pressure plates for secure, fast wiring in the field.
• Thermal Resilience: Industrial-grade 32/130 degree temperature range ensures performance in non-conditioned mechanical rooms and enclosures.
• Enhanced Circuit Safety: Includes a replaceable 3-amp fuse to protect the 1.5 Amp power supply and connected devices from electrical faults.

Common Questions

How do I adjust the output voltage?
The output voltage is field-adjustable using the onboard potentiometer. Use a small screwdriver to dial in the exact Vdc required for your specific application, such as 12Vdc or 24Vdc.

Can I use a grounded transformer with this unit?
Caution is required; a grounded secondary on the 24 VAC input transformer can blow the unit's fuse. If grounding is necessary, consider using an isolation transformer or floating the transformer secondary to prevent short circuits.

What is the maximum load this power supply can handle?
The Johnson Controls DCP-1.5-W is rated for a 1.5 Amp continuous load. For full capacity, it is recommended to use a 75 VA transformer on the input side to account for power conversion overhead.
