XT40.721 Puls AC/DC Power Supplies

Puls XT40.721 PULS XT40.721 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 (with nominal values of 380Vac, 400Vac, 415Vac; 47-63Hz), featuring a turn-ON voltage of 3 x 325Vac and a shutdown voltage of 3 x 295Vac. The unit is encased in an aluminium housing, measures W96mm x H124mm x D159mm, and uses screw-clamp connections for installation. It is rated for a current of 13.3A at 72Vdc and is designed for DIN rail mounting in a 3-phase (3AC) network. The XT40.721 can operate in ambient air temperatures ranging from -25 to +70°C. It has a peak inrush current consumption of 4A (at 3x400Vac input), a rated power of 24W/+60°C...+70°C (derating) to 960W (at 72Vdc) and 1200W for typical 15s. Protection features include output overvoltage protection (91.1Vdc max.), active input inrush current limiter, and overload/short-circuit current protection. It supports series operation but not parallel operation for increased output power, though 1+1 redundancy for higher system availability and reliability is possible. The unit is resistant to back-feeding loads up to 87.9V. It boasts an efficiency of 0.955 (with 3x400Vac input), a 400ms start-up delay, and a rise time of 40ms to 70ms depending on load capacitance. The output voltage is fixed at 72Vdc with a 1.4V turn-ON overshoot, a hold time of 3.6ms at 3x400Vdc input, power dissipation/losses of 45.2W (at 3x400Vdc input; full output load), an output stage capacitance of 4050 µF, and a ripple of 3000mVpp (20Hz...2KHz; 50Ω).
