PULS DIN RAIL POWER SUPPLY 3 PHASE 24VDC 20A 480W QT20.241

Product Code: QT20.241

The 3AC power supply is designed for a wide range of inputVoltages, specifically 380-480V. It can also be used for 2-phase operation. With an extra long lifetime, this power supply offers excellent efficiency at both full load and partial load, achieving up to 95%. Despite its powerful performance, it has a compact design with a width of only 65mm and weighs just 870g. Additionally, it provides a bonus power of 50%, allowing for a maximum output of 720W for up to 4 seconds. The power supply features active power factor correction (PFC) and active filtering of input transients. It operates at full power within a temperature range of -25°C to +60°C. Furthermore, this power supply has an extremely low input inrush current surge and includes a DC-OK relay contact. It is equipped with quick-connect spring-clamp terminals for easy installation and connection.
