QT20.481 Puls AC/DC Power Supplies

Puls QT20.481 PULS QT20.481 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 design that includes a DC-OK relay contact output. The unit provides a rated current of 10A at 48Vdc and 8.7A at 55Vdc, with a power derating applicable from 12W at +60°C to +70°C. Connection is facilitated through spring-clamp connections. It supports a wide range supply voltage from 323Vac to 576Vac across various nominal voltages (380Vac / 400Vac / 415Vac / 440Vac / 480Vac / 500Vac / 525Vac) at 47-63Hz, indicating a 3-phase input capability with specific turn-ON and shutdown voltages. The QT20.481, part of the Q-series, measures 65mm in width, 124mm in height, and 127mm in depth, housed in aluminium for durability. It is designed for a 3-phase network, with a rated power of 480W at both 48Vdc and 55Vdc, and can momentarily support up to 720W for short durations (4s). The output voltage is adjustable between 48Vdc and 55Vdc. Protection features include output overvoltage protection and active input inrush current limiting, with capabilities for overload/short-circuit protection, series/parallel operation, and back-feeding load resistance. Efficiency rates are high, at 0.95 for a 3x480Vac input and 0.954 for a 3x400Vac input. The unit exhibits a peak current consumption of 10A at both 3x400Vac and 3x480Vac inputs, with specific start-up delay and rise times. Hold time is consistent at 22ms for both 3x480Vac and 3x400Vac inputs. Power dissipation varies with input voltage, and the unit's electrical durability is rated in hours across different conditions. Ripple is maintained at 100mVpp across a 20Hz to 20MHz range, with an output stage capacitance of 250µF.
