Product Dimensions：

Phoenix Contact power supply boards and distribution modules feature compact, space-saving designs designed for standard DIN-rail mounting inside control cabinets. They convert standard alternating current or direct current input voltages into stable, low-ripple direct current output voltages, commonly standard industrial levels. Incorporating high-efficiency power electronics, these boards minimize heat dissipation, extend component lifespans, and ensure continuous operation in harsh industrial environments. Many models include integrated diagnostics, protective coatings for corrosive atmospheres, and modular expansion options to support tailored power distribution architectures.

Product Parameters

Input Voltage Range: Wide-range input supporting alternating current from 85 VAC to 264 VAC and direct current from 90 VDC to 350 VDC.
Nominal Output Voltage: Regulated 24 VDC output, with adjustable ranges between 22.5 VDC and 29.5 VDC on select models.
Output Current Rating: Rated continuously from 2.5 A up to 40 A, depending on specific module configuration and power density requirements.
Efficiency: High energy conversion efficiency typically ranging from 90 percent to 95 percent at full load.
Insulation Voltage: High electrical isolation rating of up to 4 kV AC between input and output circuits.
Operating Temperature: Extended industrial range from negative 25 degrees Celsius to positive 70 degrees Celsius, with derating starting above 60 degrees Celsius.
Electromagnetic Compatibility: Meets international immunity and emissions standards including EN 61000-6-2 and EN 61000-6-4.
Status Signaling: Integrated LED indicators and dry relay contact outputs for monitoring active power, preventive function monitoring, and fault states.

Product Advantages

Phoenix Contact power supply solutions deliver high operational reliability through advanced functional reserves, allowing systems to easily start up heavy inductive loads without voltage dips.

Their high energy efficiency reduces overall heat generation within control enclosures, allowing for higher packing density and reduced need for external cooling.

The integration of selective fuse breaking technology enables quick tripping of standard circuit breakers on fault, keeping essential system branches operational while isolating short-circuits.

Additionally, push-in or screw terminal connection options significantly streamline installation, reducing wiring time and maintenance effort during system assembly.

Important Considerations and Precautions

When installing and commissioning Phoenix Contact power boards, engineers must strictly adhere to maximum current density limits and recommended wire gauge sizes to prevent overheating at terminal connections.

Adequate clearance must be maintained above and below the module within the enclosure to ensure proper thermal convection and prevent thermal shutdown during continuous full-load operations.

Care must be taken to match incoming supply voltage ranges with the specified board parameters prior to energizing to prevent permanent damage to internal components.

For installations in hazardous locations or highly corrosive atmospheres, verify that the specific module carries appropriate certifications, such as ATEX or IECEx, and possesses protective conformal coating.

Always disconnect primary power before carrying out wiring modifications, fuse replacements, or physical installation to ensure operator safety.

Product Applications

Phoenix Contact power boards and supply systems are deployed across diverse industrial and infrastructure automation sectors.

Factory Automation: Providing stable power to PLC systems, I/O racks, human-machine interfaces, and field sensors in manufacturing facilities.
Control Cabinet Building: Serving as the central power distribution backbone inside primary and secondary control enclosures across all industrial sectors.
Energy and Power Utilities: Supplying continuous, isolated power to monitoring electronics, sub-station controllers, and renewable energy installations such as solar inverters and wind turbines.
Process Industry: Operating in chemical, petrochemical, and pharmaceutical plants where high reliability and explosive atmosphere certifications are required.
Traffic and Transportation Infrastructure: Delivering reliable power to intelligent transportation systems, signaling equipment, and railway wayside control systems.
