Product Description

The Phoenix Contact QUINT-PS-120AC/24DC/2.5 is a primary switched-mode power supply unit designed to convert 120 V AC input to a stable 24 V DC output at 2.5 A, suitable for powering industrial control systems and peripheral devices. It features a wide input voltage range of 90 V AC to 132 V AC, ensuring reliable operation across varying power conditions. The unit's high efficiency, exceeding 83%, minimizes energy loss and heat generation. Connections are facilitated through pluggable screw terminals, accommodating conductor cross-sections from 0.2 mm² to 2.5 mm². While the QUINT-PS-120AC/24DC/2.5 is no longer in production, its specifications align closely with the current QUINT-PS-120AC/24DC/2.5/F model, which includes additional filtering features.
