PHOENIX PS/1AC/24DC/20/CO 20A Switching Power Supply Module

Product Dimensions：

The Phoenix Contact QUINT-PS/1AC/24DC/20/CO is a high-performance, industrial-grade power supply unit. The “CO” designation indicates that the printed circuit boards are Conformal Coated, making it specifically designed for use in harsh environments with high humidity, dust, or corrosive gases.

Product Detailed Description

The QUINT-PS/1AC/24DC/20/CO is a primary-switched power supply that converts a single-phase AC input into a stabilized 24 V DC output. It belongs to the QUINT POWER family, which is famous for its SFB (Selective Fuse Breaking) Technology. This technology allows standard circuit breakers to trip magnetically and quickly, preventing a localized fault from shutting down the entire system.

Technical Parameters

Product Advantages

• Conformal Coating (CO): Provides superior protection against salt spray, moisture, and corrosive atmospheric pollutants (meeting ISA-S71.04-1985 G3 harsh environment standards).
• SFB Technology: Supplies up to 6 times the nominal current for 12 milliseconds, allowing individual downstream breakers to trip while the rest of the system remains powered.
• Preventive Function Monitoring: Comprehensive diagnostics via a “DC OK” signaling output and dry contact to warn the control system before a failure occurs.
• Static Power Boost: Provides up to 125% of the nominal current continuously, allowing for easy expansion or high-startup loads.
• NFC Interface: Some versions allow for wireless configuration of signaling thresholds and output voltage via a smartphone.

Important Considerations (Precautions)

• Ventilation: Maintain a minimum clearance of 50 mm above and below the unit to ensure proper convective cooling, especially when operating at full load.
• Parallel Connection: For increased power or redundancy, multiple units can be connected in parallel. However, ensure the output voltages are set to within 100 mV of each other to balance the load.
• Input Protection: Although it has internal surge protection, an external fuse or circuit breaker (typically 10 A to 16 A, B or C characteristic) is required for the input side.
• Mounting: Ensure the DIN rail is securely grounded to provide a low-impedance path for the internal EMI filter.

Product Applications

Due to the “CO” coating and high power density, this unit is ideal for:

• Oil & Gas / Offshore: Pumping stations and platforms where salt air and humidity are prevalent.
• Chemical & Petrochemical: Environments with potentially corrosive chemical vapors.
• Water & Wastewater: Treatment plants where high reliability and moisture resistance are required.
• Renewable Energy: Control cabinets for wind turbines or solar trackers in extreme outdoor climates.
• Heavy Industry: Steel mills or pulp and paper plants with significant dust and vibration.
