Title: PHOENIX QUINT-PS-3X400-500AC/24DC/20 QUINT POWER Supply - Robust 3-Phase Industrial PSU

Product Overview: The Phoenix Contact QUINT-PS-3X400 series (such as QUINT-PS-3X400-500AC/24DC/20) represents a family of powerful and highly reliable 3-phase primary-switched DIN rail power supply units. These units are designed for universal use in demanding industrial environments, providing a stable and regulated 24 V DC output from a wide-range 3-phase AC input (typically 400-500 V AC). A key feature is their "POWER BOOST" function, which allows them to reliably start heavy loads with high inrush currents, ensuring excellent system availability even in challenging conditions. With robust construction, comprehensive protection mechanisms (including overvoltage, overload, and short-circuit protection), and international approvals, QUINT POWER supplies minimize downtime and ensure consistent performance for critical control systems, PLCs, and various industrial machinery worldwide. They are ideal for applications where reliability, efficiency, and stable power are paramount.

Key Features & Benefits:

POWER BOOST Function: Provides a temporary power reserve (e.g., 150% of nominal current for 5 seconds or 200% for 3 seconds) to reliably start heavy loads with high inrush currents, preventing system outages.
Wide Input Voltage Range: Accepts a broad 3-phase AC input (typically 320-575 V AC), offering versatility for global applications and varying grid conditions.
High Efficiency: Achieves high efficiency (typically >91% at 400 V AC), leading to significant energy savings and reduced heat generation within the control cabinet.
Preventive Function Monitoring: Features active diagnostic outputs (e.g., DC OK signal via transistor output and floating relay contact) that report critical operating states before errors occur, minimizing unplanned downtimes.
Mains Buffering: Generously dimensioned capacitors ensure mains buffering of typically over 20 ms at full load, bridging short power failures.
Robust Industrial Design: Built with durable metal (AluNox) housing and IP20 protection, designed to withstand harsh industrial conditions including temperature fluctuations (-25 °C to +70 °C), vibration, and shock.
Parallel and Series Connection: Supports both parallel connection for redundancy or increased capacity, and series connection for higher output voltages.
Adjustable Output Voltage: The output voltage can be finely adjusted from 22.5 V to 28.5 V DC to suit specific application requirements.
Comprehensive Protection: Includes protection against overvoltage, overload, short-circuit, and thermal overload, safeguarding both the power supply and connected equipment.
International Approvals: Comes with a comprehensive package of international approvals (e.g., UL, CUL, CE), enabling worldwide application.
