Johnson Controls DCP-250-D Power Supply

The Johnson Controls DCP-250-D is a specialized regulated 24VDC power supply engineered specifically for integration within Building Automation Systems (BAS) and temperature control environments. This robust, enclosed DC power supply converts 110-125 VAC line voltage into a stabilized 24VDC output with a 250 mA maximum load, making it an ideal choice for powering 4-20mA transmitters, pressure transducers, and low-draw actuators. Designed for rapid deployment in high-density control panels, the DCP-250-D features 1/2" DIN rail mounting and 20-inch color-coded 18 AWG lead wires to streamline field wiring and reduce installation labor. Its transformer-isolated design and built-in LED indicator ensure consistent HVAC power supply performance across a wide operating temperature range of -22? to 104?F, providing the reliability demanded by veteran contractors managing critical commercial infrastructure and energy management systems.

• Regulated Output: Maintains a steady 23.5-24.5 VDC range to protect sensitive sensors and control boards from voltage fluctuations.
• Efficient Integration: Specifically designed for DIN rail mounting, allowing for clean, space-saving arrangement within electrical enclosures.
• Field-Ready Leads: Pre-stripped 20-inch leads facilitate easy connections to line voltage and low-voltage field devices without additional jumper wires.
• Contractor-Grade Durability: The fully enclosed housing protects internal components from dust and debris commonly found in mechanical rooms.

Is the DCP-250-D suitable for powering multiple HVAC controllers?
Provided the total current draw of all connected devices does not exceed the 250 mA maximum load, this unit can power multiple low-voltage components in a single loop.

Can I use this for 50/60 Hz applications?
Yes, the internal circuitry is designed to handle 50/60 Hz frequencies, making it compatible with various standard electrical service configurations.

Does it require a separate enclosure if mounted on a DIN rail?
While the unit is fully enclosed and safe for panel interior mounting, it should always be housed within a protected NEMA-rated enclosure or control cabinet to comply with local electrical codes.
