Product Description
Part of the QUINT POWER family, it combines SFB (Selective Fuse Breaking) technology, which supplies brief high-current pulses to trip downstream circuit breakers selectively, with a static POWER BOOST reserve for starting heavy loads. Wide-range 85-264 V AC input, high efficiency and integrated diagnostics make it a dependable 24 V DC source for control cabinets and process automation. The Phoenix Contact 2866789 is the QUINT-PS/1AC/24DC/40 primary-switched DIN rail power supply, delivering a regulated 24 V DC output at up to 40 A (960 W) from a single-phase AC input.
Basic Product Information
- Regulated 24 V DC output, adjustable 18-29.5 V DC, rated 40 A / 960 W
- SFB (Selective Fuse Breaking) technology delivers up to about 215 A for 12 ms to trip standard breakers
- POWER BOOST reserve (45 A) for starting capacitive and inductive loads
- Fanless convection cooling in a metal housing, IP20, DIN rail mounting
- DC OK signalling contact and LED status indicators for system monitoring
- Single-phase AC input 85-264 V AC with wide-range automatic adjustment
Technical Specifications
Version & Model Difference
