Stand-by loss only 0.2 watt. With a load greater than 50% of the rated power and always with adjacent switching power supplies from 12 watts rated power and with dimmers, a 1/2 pitch unit ventilation distance is required on both sides with the DS12 spacers. Efficiency 83%. Stabilized output voltage ±1%, low ripple. Short circuit proof. Overload and overtemperature protection by switching off with automatic switching on after fault clearance (autorecovery function).
