QUINT-PS-3X400-500AC/24DC/40
Three-phase, primary-switched DIN rail power supply delivering 24 V DC at 40 A for plant engineering and special-purpose machinery.
Order number 2938646 combines a wide AC/DC input, POWER BOOST reserve, adjustable output voltage and two DC OK interfaces for remote diagnostics.
High-current 24 V DC supply for industrial loads
QUINT-PS-3X400-500AC/24DC/40 converts a three-phase industrial supply into regulated 24 V DC. Its POWER BOOST reserve supports loads with demanding starting current, while the output can be adjusted from 22.5 V to 28.5 V.
The device accepts all three phases from 320 V AC to 575 V AC and can also operate from 450 V DC to 800 V DC. A DC OK active output and floating relay contact allow operating status to be transferred to a control or monitoring circuit.
POWER BOOST
45 A is available continuously from −25°C to +40°C.
Remote diagnostics
Active DC OK output and floating relay contact report output status.
Flexible operation
