SDR-240-48 MEAN WELL AC/DC Power Supplies

CP20.241

PULS CP20.241 is a DIN rail mounting power supply unit with an aluminium housing. It operates within an ambient air temperature range of -25 to +70°C and has a net width of 48 mm. The unit features a current consumption of 5.5A peak max. inrush at 230Vac input and 12A peak max. inrush at 120Vac input. Its efficiency rates are 0.956 at 230Vac input, 0.942 at 120Vac input, and 0.936 at 100Vac input. The dimensions of the CP20.241 are W48mm x H124mm x D127mm. It has a 450ms start-up delay for 100-230Vac input, with rise times of 145ms and 160ms under nominal input conditions with 0mF and 20mF load capacitance, respectively. Protection functions include output overvoltage protection and overload/short-circuit protection, with the capability for series or parallel operation for increased output voltages or power. The unit is resistant to back-feeding loads up to 35V. Power dissipation/losses are 22.1 W at 230Vac input and 29.6 W at 120Vac input, with an output stage capacitance of 8500 µF. Electrical durability varies with conditions, offering up to 488000 hours of operation. The ripple is 50mVpp (20Hz...20MHz; 50Ω). This AC/DC power supply unit is part of the CP-series, designed with ATEX approval and a 20% power reserve, featuring a DC-OK relay contact output and screw-clamp connections. It supports a supply voltage range of 88Vdc-180Vdc and 85Vac-264Vac, with a rated current of 20A at 24Vdc, and provides a rated power of 480W. The output voltage is adjustable between 24Vdc and 28Vdc, with a 500mV turn-ON overshoot and a hold time of 32ms at 120/230Vac input.
