Switching power supply. Nominal power 48W. Stand-by loss only 0.2 watts. Modular devices for mounting on DIN-EN 60715 TH35 mounting rail. 2 division units = 36mm wide, 58mm deep. With a load greater than 50% of the nominal power and always with adjacent switching power supplies with a nominal power of 12 watts or more and with dimmers, 1/2 division unit ventilation clearance with the DS12 spacers is required on both sides. Wide range input voltage 88-264V AC (110V-20% to 240V +10%). Efficiency 92%. Stabilized output voltage ±1%, low residual ripple. Short-circuit proof. Overload and overtemperature protection by switching off with automatic switching on after the error has been eliminated (autorecovery function).
