CT10.481

PULS CT10.481 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 62mm. The unit consumes 0.6A with a 3 x 480Vac input and 0.7A with a 3 x 400Vac input, both at full 48Vdc output, with a peak inrush current of 10A. It boasts an efficiency of 0.929 for 3x480Vac input and 0.928 for 3x400Vac input. The dimensions are W62mm x H124mm x D117mm. It includes a 90ms start-up delay, a 55ms rise time at nominal input with a constant full current load and 0mF load capacitance, and a 140ms rise time with 5mF load capacitance. The unit features output overvoltage protection, an active input inrush current limiter, and supports series/parallel operation for increased output power. It is resistant to back-feeding loads up to 63V. Power dissipation/losses are 18.3W for 3x480Vac input and 18.6W for 3x400Vac input at full output load. The output stage capacitance is 2400µF. Electrical durability ranges from 78,000 to 704,000 hours depending on the operating conditions. The ripple is 100mVpp (20Hz...20MHz; 50Ω). This AC/DC power supply unit/converter offers a 20% power reserve and includes a DC-OK relay contact output. It features screw-clamp connections and supports a supply voltage of 323Vac-576Vac (wide range; 3-phase input) with a rated current of 6A at 48Vdc from -25 to +45°C and 3.75A at 48Vdc from -25 to +70°C. The output voltage is adjustable between 48Vdc and 56Vdc, with a hold time of 54ms at 3x480Vac input and 34ms at 3x400Vac input.
