Power supply for 24 V actuators. 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 division unit ventilation distance with the spacers DS12 is required. Efficiency: 86%. Stabilised output voltage ±1%, low ripple. Short circuit proof Overload and overtemperature protection by switching off with automatic switch-on after the fault removal (autorecovery function). The 24 V DC output of these switching power supplies is located below so that the busbars SAS - a quick connection to the actuators FAE14LPR for 24 V DC actuators can be established. The SNT14 is always mounted to the right of the last actuator FAE14LPR as there is no jumper available.
