QUINT-PS/1AC/24DC/40 Phoenix Contact 2866789 Manual

Phoenix Contact QUINT-PS/1AC/24DC/40 DIN-Rail Power Supply

The Phoenix Contact QUINT-PS/1AC/24DC/40, also cataloged as the 2866789 Industrial DIN-rail power supply, operates as a dedicated hardware component for AC-to-DC and DC-to-DC power conversion within automated control panels. It delivers regulated DC electrical power to active electronic loads from a single-phase AC or high-voltage DC primary source link.

Hardware Specifications

Industrial Network and Power Infrastructure Attributes

The electrical topology incorporates intrinsic safety and transient suppression configurations, limiting voltage fluctuations via integrated surge voltage protection limits. The power supply utilizing Selective Fuse Breaking (SFB) technology provides a dynamic power reserve capable of generating 6x nominal current for a 12 ms window to trigger downstream standard circuit breakers during a short-circuit fault condition. Continuous operations are supported by a permanent static POWER BOOST reserve of 1.5x nominal current, while maintaining physical DIN-rail mounting stability under heavy structural loads.

Frequently Asked Questions

Q: What are the functional switching parameters governing the hot-swap or active maintenance of this power supply unit?

A: The QUINT-PS/1AC/24DC/40 does not feature modular hot-swap capabilities on its base frame. Complete isolation of the primary 85-264 VAC input line and wait times for internal capacitor discharge must be enforced before removing the hardware from the DIN-rail interface.

Q: How does the power supply maintain output stabilization when transient dropouts occur on the primary network grid?

A: The internal storage capacitance matrix establishes an electrical hold-up time metric exceeding 35 ms when operating at nominal 120/230 VAC input thresholds, maintaining 24 VDC output regulation during brief supply micro-interruptions.

Q: What protocol conversion latencies or monitoring signaling states are integrated into the hardware?

A: The unit features a localized analog diagnostic matrix and preventive monitoring outputs that flag active status variables before critical low-voltage or thermal faults drop out the main DC bus bar.

Field Installation Guidelines

• DIN-Rail Seating and Orientation: Hook the upper alignment tab of the power supply housing onto the standard NS 35 DIN-rail. Snap the lower section downward until the internal steel locking latch clicks into place to secure formal physical mounting stability.
• Convection and Air Clearance Paths: Ensure the module is mounted exclusively in a vertical orientation to accommodate passive convection cooling. Maintain a minimum clear physical buffer zone of 50 mm above and below the chassis to prevent thermal load accumulation.
• Shielding and Structural Earth Grounding: Connect a low-impedance copper grounding conductor directly from the primary PE wire terminal to the main equipment enclosure ground bar. This connection path routes common-mode noise and satisfies internal surge voltage protection limits.
• Termination Torque and Separation Rules: Tighten all input and output screw clamps to the manufacturer's specified tightening torque parameters. Separate high-voltage AC source cables from low-voltage 24 VDC output lines within the wiring paths to eliminate EMI induction.
