Product description

480W, 48V, 10A 3-phase DIN rail power supply from PULS' Q-Series, featuring wide-range 3AC 380-480V input, 95.4% efficiency, and 50% BonusPower®.

The PULS QT20.481 is a Q-Series AC/DC DIN rail power supply designed for 3-phase systems. It provides a continuous output power of 480W with an adjustable output voltage from 48V DC to 55V DC, delivering 10A at 48V DC and 8.7A at 55V DC. The unit accepts a wide-range 3-phase AC input of 380-480V (±15%) or 323-576Vac, suitable for 380Vac / 400Vac / 415Vac / 440Vac / 480Vac / 500Vac / 525Vac nominal systems with a frequency range of 47-63Hz. It boasts a high full-load efficiency of 95.4% and includes active Power Factor Correction (PFC). A key feature is 50% BonusPower®, providing up to 720W (150% of rated power) for up to 4 seconds, supporting short-term peak loads. The power supply also incorporates an active input inrush current limitation and a potential-free DC-OK relay contact for signaling. It is housed in a compact 65mm wide enclosure for DIN rail mounting and utilizes spring-clamp connections.
