The fixed output voltage is 36Vdc with a 700mV turn-ON overshoot, and it offers a hold time of 2.6ms (buffer time at 3x400Vdc input). Power dissipation/losses are calculated at 45.2 W (3x400Vdc input; full output load), and the electrical durability is rated at 55000 hours (at 40°C; 26.6A output; 3AC 400Vdc input) to 156000 hours (at 25°C; 26.6A output; 3AC 400Vdc input). The output stage capacitance is 11100 µF, with a ripple of 2000mVpp (20Hz...2KHz; 50Ω).

PULS XT40.481 is a power supply unit part of the X-series, designed to function as an AC/DC PSU/converter with a semi-regulated 25% power reserve and a DC-OK relay contact output. It operates on a supply voltage of 3x360-440Vac (380Vac / 400Vac / 415Vac nominal; 47-63Hz), with a turn-ON voltage of 3 x 325Vac and a shutdown voltage of 3 x 295Vac. The unit is housed in aluminium, featuring screw-clamp connections for secure installation and is designed for DIN rail mounting. It supports a 3-phase (3AC) network type and can operate within an ambient air temperature range of -25 to +70°C. The XT40.481 has a net width of 96mm and dimensions of W96mm x H124mm x D159mm. It is rated for a current of 20A at 48Vdc, with a peak inrush current consumption of 4A (at 3x400Vac input). The rated power is 960W at 48Vdc, with a derating to 24W between +60°C and +70°C, and can momentarily support up to 1200W for approximately 15 seconds. Protection features include output overvoltage protection (57.2Vdc max.), active input inrush current limiter, and overload/short-circuit current protection, typically 90A at load impedance. It is not designed for series or parallel operation to increase output power but supports 1+1 redundancy for higher system reliability. The unit is resistant to back-feeding loads up to 55.1V. It boasts an efficiency of 0.96 (at 3x400Vac input), with a 400ms start-up delay, a rise time of 40ms (at nominal input with 0mF load capacitance) to 70ms (with 20mF load capacitance), and a fixed output voltage of 48Vdc with a 1V turn-ON overshoot. The hold time is 3.1ms at 3x400Vdc input, with power dissipation/losses at 40W (full output load). Its electrical durability is rated at 77000 hours (at 40°C; 20A output; 3AC 400Vdc input) to 15 years / 131400 hours (at 25°C; 20A output; 3AC 400Vdc input). The output stage capacitance is 7600µF, with a ripple of 2500mVpp (20Hz...2KHz; 50Ω).
