CD5.121

PULS CD5.121 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 current consumption of 4.6A with a 24Vdc input for a full 12Vdc output, and a peak inrush current of 1.6A. The unit boasts an efficiency of 0.882 under a 12Vdc 8A input and has dimensions of W32mm x H124mm x D102mm. It includes a 420ms start-up delay and a 210ms rise time under nominal input with a constant full current load. The CD5.121 offers protection functions such as output overvoltage protection, short-circuit current protection, and allows for series/parallel operation for increased output power or redundancy. It is resistant to back-feeding loads up to 16V and includes reverse polarity protection. Power dissipation/losses are 12.8W with a 24Vdc input and 12V output load at 8A, and the output stage capacitance is 6500µF. Its electrical durability is rated at 173000 hours at 40°C with a 4A output. The ripple is 75mVpp, and it features screw-clamp connections. The supply voltage ranges from 18Vdc to 32.4Vdc, with a rated current of 9.6A at 12Vdc up to 45°C and 8A at 12Vdc up to 60°C, including a derating above 60°C. The rated power is 116W in ambient temperatures less than 45°C and 96W in temperatures less than 60°C. The output voltage is adjustable between 12Vdc and 15Vdc, with a 500mV turn-ON overshoot and a hold time of 7ms.
