CD5.242

PULS CD5.242 is a power supply unit designed for DIN rail mounting, featuring an aluminium housing. It operates within an ambient air temperature range of -25 to +70°C and has a net width of 32 mm. The unit consumes 2.75A current at a 48Vdc input to deliver a full 24Vdc output at 5A, with a peak inrush current of 0.8A. It boasts an efficiency of 0.903 at a 24Vdc, 5A input. The dimensions are W32mm x H124mm x D102mm. It includes a 670ms start-up delay and an 80ms rise time under nominal input with a constant full current load. The CD5.242 offers protection against output overvoltage, short circuits, and allows for series or parallel operation for increased output power or redundancy. It is resistant to back-feeding loads up to 30V and includes reverse polarity protection. Power dissipation losses are 12.9W at a 48Vdc input with a 24V output load at 5A. The output stage capacitance is 2200 µF. Its electrical durability ranges from 39,000 to 181,000 hours depending on conditions. The ripple is 50mVpp from 20Hz to 20MHz. This PSU/DC/DC-Converter supports a 20% power reserve and is designed with ATEX approval for galvanic isolation. It features screw-clamp connections and accepts a supply voltage of 39Vdc-57Vdc (48Vdc nominal), with a short-term tolerance down to 30.5-36Vdc for up to 60 seconds. The rated current is 6A at 24Vdc in temperatures up to 45°C, with derating applied up to +70°C. The rated power is 144W in ambient temperatures less than 45°C and 120W below 60°C. The output voltage is adjustable between 23-28Vdc, with a 500mV turn-ON overshoot, and it has a hold time of 5.6ms at a 48Vdc input.
