Product QUINT-PS-3X400-500AC/24DC/40 2938646

QUINT-PS-3X400-500AC/24DC/40 (Part Number: 2938646) is a powerful 960 W DC power supply unit from the QUINT POWER series, designed for universal use. With its wide-range input, three-phase version, and international approval package, this solution is unrivalled. QUINT POWER provides reliable power supply: generously dimensioned capacitors ensure mains buffering of over 20 ms at full load. Full output power is provided even in the event of a permanent phase failure. The Power Boost power reserve easily starts loads with high inrush currents and ensures that fuses are reliably tripped. Preventive function monitoring diagnoses impermissible operating states and minimizes downtimes in your system. Remote monitoring is provided by an active transistor switching output and a floating relay contact. This device delivers a regulated and adjustable 24 V DC output voltage with a 40 A output current. It is idling-proof and short-circuit-proof, and is suitable for use in Ex zone 2 applications.

Technical Specifications

Features

➟Power Boost for Heavy Load Start-up: The integrated Power Boost provides up to 45 A output current (at -25°C to +40°C) to reliably start loads with high inrush currents and ensure that connected fuses are tripped without issues .

➟Superior Mains Buffering: Generously dimensioned capacitors guarantee a mains buffering time of > 20 ms at full load (400 V AC / 480 V AC), protecting the system from power fluctuations and momentary interruptions .

➟Robust and Protection Features: The unit is idling-proof and short-circuit-proof, featuring active current limitation (approx. 45 A) and protection against overvoltage at the output (≤ 35 V DC) . It also includes transient surge protection via a varistor .

➟Flexible Parallel and Series Connection: Devices can be connected in parallel for redundancy or increased capacity, or in series for higher voltages, offering flexible system design options .
