QUINT-PS/3AC/24DC/40

This listing is for a used and fully tested QUINT-PS/3AC/24DC/40 industrial DIN rail power supply (order no. 2866802), a primary-switched unit from the QUINT POWER series designed for demanding three-phase automation environments. The unit accepts a wide three-phase AC input range of 320–575 V AC and delivers a stable, regulated 24 V DC output at 40 amps — totaling 960 watts of continuous output power. Its output voltage is also field-adjustable from 18 V DC to 29.5 V DC, giving engineers the flexibility to fine-tune the supply to match exact system requirements.QUINT-PS/3AC/24DC/40

One of the standout features of this power supply is its SFB (Selective Fuse Breaking) Technology, which delivers up to six times the nominal current for 12 milliseconds to reliably and quickly trip standard circuit breakers on faulty branches — isolating faults without taking down the rest of the system. Complementing this is built-in preventive function monitoring, which continuously tracks output voltage and current and signals critical operating conditions before actual failures occur. The POWER BOOST static reserve also ensures reliable startup of heavy loads. Together, these capabilities make this supply a strong choice for high-availability machine control panels, process automation cabinets, and factory infrastructure.

Every unit in this listing has been inspected and operationally tested prior to sale, offering a cost-effective path to sourcing proven industrial hardware. The efficiency rating exceeds 94% at 400 V AC nominal load, with an MTBF exceeding 501,000 hours per IEC 61709/SN 29500 — figures that reflect the long-term reliability this platform is known for in the field. The operating temperature range of -25 °C to +70 °C and a -40 °C cold-start capability make it suitable for a broad range of installation environments.QUINT-PS/3AC/24DC/40

The supply mounts horizontally on a standard NS 35 DIN rail and uses screw-type connections for both input and output wiring. It weighs approximately 2.5 kg and carries the protections and certifications expected for industrial-grade equipment, including transient surge protection via varistor and gas-filled surge arrester. Whether you are repairing a panel, expanding capacity, or stocking a spare, this is a field-proven component ready to go back to work.QUINT-PS/3AC/24DC/40

SFB Technology: Selective Fuse Breaking delivers up to six times nominal current for 12 ms, reliably tripping standard circuit breakers on faulty branches without affecting the rest of the system.
