2900274

Overview

Phoenix Contact part number 2900274 is a QUINT series regulated AC/DC switched-mode power supply unit. It features a single-phase input voltage range of 100 to 240 VAC and provides a stable 28 VDC output at a rated current of 8.5 A, delivering a total power capacity of 240 W. The device utilizes screw-clamp connections for secure wiring and is designed for DIN rail mounting in industrial control cabinets. It includes remote signaling capabilities for DC-OK status monitoring.

Feature Summary

• Provides regulated 28 VDC output with high current capacity
• Features wide-range AC input compatibility
• Includes remote DC-OK signal contact for system monitoring

Applications

• Industrial automation control panels
• Process control systems requiring 28V DC logic power
• Machine building electrical enclosures

Procurement Notes

Verify the specific catalog designation QUINT-PS-100-240AC/28DC/8.5 GE when ordering to ensure correct output voltage and current ratings. Confirm that the application requires a 28 VDC supply rather than the more common 24 VDC variant. Check for regional availability as distribution may vary by location.

Selection Notes

Select this model specifically for applications demanding 28 VDC logic levels. Ensure the load current does not exceed 8.5 A continuous operation. Verify that the enclosure supports DIN rail mounting and allows for adequate ventilation given the 240 W power dissipation characteristics.

Part Context

This component belongs to the Phoenix Contact QUINT series of power supplies, known for compact design and high reliability in industrial environments. It serves as a critical interface between mains AC power and low-voltage DC control circuits within automated machinery and infrastructure systems.

Replacement Considerations

Direct substitutes must match the 28 VDC / 8.5 A specification. Generic 24 VDC replacements are incompatible due to voltage mismatch. Verify pinout and mounting dimensions if cross-referencing with other manufacturers' DIN rail units.
