Stand-by loss only 0.2 watts. 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 is 86%. Stabilized output voltage is ±1% with low ripple. It is short circuit proof and has overload and overtemperature protection by switching off with automatic switching on after fault clearance (autorecovery function).
