CPS20.481

PULS CPS20.481 is a DIN rail mounting power supply unit with an aluminium housing designed for a wide range of industrial applications. It operates within an ambient air temperature range of -25 to +70°C and offers a net width of 65mm. The unit consumes 2.33A with a 230Vac input for full 48Vdc output, 4.36A with a 120Vac input, and 5.25A with a 100Vac input, with a peak inrush current of 13A at both 230Vac and 120Vac inputs. It features an IP20 degree of protection and achieves efficiencies of 0.939, 0.926, and 0.92 at 230Vac, 120Vac, and 100Vac inputs respectively. The dimensions of the CPS20.481 are W65mm x H124mm x D127mm. It has a start-up delay of 850ms and rise times of 90ms and 230ms under specified conditions. The unit is equipped with protection functions including output overvoltage protection and overload/short-circuit protection, and supports series/parallel operation for increased output power. It can handle back-feeding loads up to 63V without malfunctioning. Power dissipation/losses are rated at 31.2W, and the output stage capacitance is 2450µF. Electrical durability varies with conditions, reaching up to 475000 hours. The ripple is specified at 50mVpp. This AC/DC power supply unit offers a 20% power reserve, is part of the C-series, and comes with ATEX approval and a DC-OK relay contact output. Connection is made via screw-clamp connections. It accepts a supply voltage range of 85Vac-264Vac, with specific shutdown voltages under varying loads. The rated current is 10A at 48Vdc with derating above 60°C. Designed for single-phase networks, it provides a rated power of 576W with PowerBoost below 45°C and 480W below 60°C. The output voltage is adjustable between 48Vdc and 56Vdc, with a 200mV turn-ON overshoot and a hold time of 26ms.
