PIC240.241D

PULS PIC240.241D is a power supply unit designed for DIN rail mounting, featuring AC/DC conversion capabilities. It operates within an ambient air temperature range of -25 to +70°C and includes a DC-OK relay contact output. The unit provides a rated current of 20A at 24Vdc, with screw-clamp connections for secure installation. It supports a supply voltage range of 85Vac to 264Vac across various nominal voltages from 100Vac to 240Vac at a frequency of 47-63Hz, featuring a 150Vac turn-ON voltage and a 130Vac shutdown voltage. The PIC-series part measures 59mm in width, 124mm in height, and 127mm in depth, housed in a polycarbonate casing. It is suitable for single-phase networks and offers a rated power of 480W, with an adjustable output voltage range of 24Vdc to 28Vdc. Protection functions include output overvoltage protection, NTC for input inrush current limiting, and overload/short-circuit protection. The unit allows for series or parallel operation for increased output ampacity or redundancy, with a resistance to back-feeding loads up to 35V. Efficiency rates vary by input voltage, achieving up to 0.953 at 230Vac. It features a peak inrush current consumption of 48A at 230Vac, with a start-up delay of 420ms and a hold time of 27ms at both 230Vac and 120Vac inputs. Power dissipation losses are noted at 23.7W for 230Vac input under full load. The electrical durability spans up to 557,000 hours at 25°C with a 10A load on a 1AC 230Vac input. Ripple is maintained at 100mVpp across a 20Hz to 20MHz frequency range, with an output stage capacitance of 4300µF.
