SPDE484801R is a high-efficiency DIN-rail mounted power supply delivering 480 W of output power at 48 VDC with a rated output current of 10 A. It accepts single-phase AC input from 100 VAC to 240 VAC (47–63 Hz) and features built-in active power factor correction (PFC) with a power factor of 0.99 at both 115 VAC and 230 VAC. The unit achieves 94% efficiency at full load and includes comprehensive protection functions: output short circuit, over-current, over-voltage, and over-temperature protection, plus a DC OK relay output (30 VDC / 1 A max.) that closes when output voltage reaches 90% of rated value. With an output voltage regulation span of 48 V to 56 V, voltage accuracy of ±1%, and ripple/noise specifications of 60–120 mV (20 MHz bandwidth), this supply is designed for industrial equipment and machinery installations where space is limited and reliable power delivery is essential.
