Phoenix Contact 2866705 QUINT-PS/ 3AC/24DC/10 power supply content_copy

The QUINT-PS/ 3AC/24DC/10 power supply from Phoenix Contact is a primary-switched, pluggable unit designed for use in industrial automation systems. It is intended for supplying control systems, sensors, actuators, and other electronic components with a constant direct voltage. The device delivers an output voltage of 24 V DC with a maximum output current of 10 A and draws power via a 3-phase alternating current input. The power supply is designed for use in enclosures and features a pluggable screw connection, enabling flexible and secure mounting.

Applications

The QUINT-PS/ 3AC/24DC/10 is suitable for applications in industrial automation, particularly in environments with high requirements for reliability and operational safety. It is commonly used in production plants, material handling systems, machine building, and packaging technology, where continuous and stable power supply for electronic control and regulation systems is required. The 3-phase input supply enables efficient use in installations equipped with a three-phase power supply.

Functions and Features in Detail

A central feature of the power supply is SFB Technology (Selective Fuse Breaking), which enables selective protection in the event of a short circuit or overload. This ensures that only the affected circuit is switched off, while the rest of the system continues to operate. This enhances operational safety and reduces downtime. The pluggable screw connection simplifies installation and maintenance, as the device can be mounted on standard DIN rails without tools.

Technology Explained Simply

The primary-switched circuit ensures high efficiency and low power loss. The input side is powered by a 3-phase alternating voltage, which is converted within the power supply into a regulated direct voltage of 24 V DC. The output current of 10 A allows simultaneous supply of multiple loads. The SFB technology operates with an integrated protection mechanism that selectively responds to overload or short circuit, protecting the entire system.

Compatibility and Accessories

The power supply can be combined with various accessories that extend its functionality. These include thermomagnetic device protection switches from the CB TM1 series in various rated currents (1 A, 2 A, 3 A, 4 A, 5 A), which can be used for additional protection. For redundant power supplies, redundancy modules such as the QUINT-ORING/24DC/2X10/1X20 or the TRIO-DIODE/12-24DC/2X10/1X20 are available. Diode modules such as the QUINT-DIODE/12-24DC/2X20/1X40 enable parallel supply of loads. For mounting on non-standard rails, adapters such as the UTA 107 or UWA 182/52 can be used. Surge protection devices of types PLT-SEC-T3-3S-230-FM and PLT-SEC-T3-24-FM-UT offer additional protection against transient voltage spikes. A fan module QUINT-PS/FAN/4 can be added for cooling under high load or in warm environments.

Mounting and Installation

The power supply is mounted on DIN rails, with the pluggable screw connection enabling easy and secure connection. Mounting is tool-free, which speeds up installation and maintenance. The unit is designed for use in enclosed enclosures, with environmental conditions meeting the requirements of industrial use.

Operational Advantages

The combination of primary-switched circuitry, SFB technology, and pluggable screw connection provides high operational safety, easy installation and maintenance, and efficient energy conversion. The 3-phase input supply enables stable power delivery even under fluctuating grid conditions. Compatibility with various accessories expands application possibilities and allows customized solutions for different applications.
