QS5.241

PULS QS5.241 is a power supply unit designed for AC/DC conversion with a 50% power reserve, suitable for DIN rail mounting. It operates within an ambient air temperature range of -25 to +70°C and features a DC-OK relay contact output for enhanced monitoring. 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 across various nominal values and from 88Vdc to 360Vdc, ensuring flexibility across different power networks. The QS5.241, part of the Q-series, is housed in an aluminium casing, measuring 40mm in width, 124mm in height, and 117mm in depth. 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, with comprehensive protection functions including output overvoltage protection and overload/short-circuit protection. It allows for series or parallel operation to increase output power and is designed to handle back-feeding loads without malfunctioning. The unit boasts high efficiency rates up to 0.927 depending on the input voltage and has a peak current consumption of 15A. It features a start-up delay of 85-120ms, with a rise time of 18ms to 38ms depending on load capacitance, and a hold time of 34ms to 65ms. Power dissipation is minimized, and the unit demonstrates exceptional electrical durability, with operational lifespans ranging up to 252000 hours under optimal conditions. The output stage capacitance is 3500µF, and ripple is maintained at 50mVpp, ensuring stable power delivery.
