CPS20.121

PULS CPS20.121 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 supports a net width of 65 mm. The unit consumes 1.8A, 3.3A, and 4A under 230Vac, 120Vac, and 100Vac input conditions respectively, with a peak inrush current of 13A at both 230Vac and 120Vac inputs. It boasts an efficiency of up to 0.926, 0.914, and 0.909 under 230Vac, 120Vac, and 100Vac inputs respectively. The dimensions are W65mm x H124mm x D127mm. It features a start-up delay of 700-900ms and rise times of 72ms and 120ms under nominal input conditions. The CPS20.121 includes protection functions such as output overvoltage protection and overload/short-circuit protection, with the capability for series or parallel operation to increase output power. It is designed to handle back-feeding loads up to 16V without malfunctioning. Power dissipation/losses are calculated at 28.8 W, with an output stage capacitance of 5600 µF. Its electrical durability ranges from 50,000 to 492,000 hours, depending on operating conditions. The ripple is maintained at 100mVpp. This AC/DC power supply unit offers a 20% power reserve, is part of the C-series, and includes ATEX approval, DC-OK relay contact output, and screw-clamp connections. It accepts a supply voltage range of 85Vac-264Vac, with specific shutdown voltages under varying loads. The rated current is 30A at 12Vdc, with a rated power of 405W at 15Vdc and 360W at 12Vdc. The output voltage is adjustable between 12Vdc and 15Vdc, featuring a 200mV turn-ON overshoot and a hold time of 35ms.
