QS5.241-A1

PULS QS5.241-A1 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 boasts ATEX approval, conformal coating, and a DC-OK relay contact output for enhanced functionality. The unit provides a rated current of 5A at 24Vdc and 4.5A at 28Vdc, with spring-clamp connections facilitating secure and reliable connectivity. It supports a wide supply voltage range from 85Vac to 264Vac for AC inputs and 88Vdc to 360Vdc for DC inputs, ensuring versatility across different power networks. The QS5.241-A1, part of the Q-series, measures 40mm in width, 124mm in height, and 117mm in depth, housed in a durable aluminium casing. It delivers a rated power of 120W at 24V and 126W at 28V, with a short-term capacity of 180W for up to 4 seconds. The output voltage is adjustable between 24Vdc and 28Vdc, and the unit includes comprehensive protection functions against overvoltage, overload, and short circuits. It is designed for single-phase or DC networks and demonstrates high efficiency rates up to 0.927, depending on the input voltage. The QS5.241-A1 also features a peak inrush current of 15A, a start-up delay between 85 to 120ms, and a hold time of up to 65ms, depending on the input voltage. Power dissipation is minimized to 9.4W at full output load with a 230Vac input. Its electrical durability is rated up to 252,000 hours at optimal conditions, with a ripple of 50mVpp and an output stage capacitance of 3500µF, ensuring stable and reliable operation over its lifespan.
