QS20.361

PULS QS20.361 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 monitoring purposes. The unit provides a rated current of 13.3A at 36Vdc and 11.4A at 42Vdc, 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 188Vdc, ensuring flexibility across different power networks. The QS20.361, part of the Q-series, measures 82mm in width, 124mm in height, and 127mm in depth, housed in a durable aluminium casing. It delivers a rated power of 480W, with a short-term capacity of 720W for up to 4 seconds, and an adjustable output voltage between 36Vdc and 42Vdc. Protection features include output overvoltage protection and active input inrush current limiting, alongside capabilities for overload and short-circuit management. The unit is designed for both single-phase AC or DC networks and offers high efficiency rates up to 0.94 depending on the input voltage. It also allows for series or parallel operation to increase output power, with specific attention to maintaining uniform output voltage across paralleled units. The QS20.361 exhibits a low power dissipation, high electrical durability across various conditions, and minimal ripple, alongside a significant output capacitance of 8500µF, ensuring stable and consistent power supply performance.
