QS40.241

PULS QS40.241 is a power supply unit designed for DIN rail mounting, featuring AC/DC conversion with a 50% power reserve. It operates within an ambient air temperature range of -25 to +70°C and has ATEX approval. The unit provides a rated current of 40A at 24Vdc and 34.3A at 28Vdc, with screw-clamp connections for installation. It supports a supply voltage range of 85Vac-264Vac across various nominal voltages and frequencies, with specific turn-ON and shutdown voltages. Part of the Q-series, it measures 125mm in width, 124mm in height, and 127mm in depth, housed in aluminium. Designed for single-phase networks, it offers a rated power of 960W, extendable to 1440W for short-term applications, and an adjustable output voltage between 24Vdc and 28Vdc. The unit includes protection against overvoltage, with active input inrush current limitation and overload/short-circuit protection. It allows for series or parallel operation for increased output power, with specific conditions for back-feeding loads. The efficiency rates vary with input voltage, and it features specific current consumption, time delay, and hold time values. Power dissipation/losses are detailed alongside electrical durability metrics under various conditions. The output ripple is specified at 100mVpp, with an output stage capacitance of 10200µF.
