Wide-range switching power supply unit. Rated capacity 24W. Standby loss 0.2 watt only. Modular devices for DIN 60715 TH35 rail mounting. 2 modules = 36mm wide, 58mm deep. At a load of more than 50% of the rated capacity and always if there are adjacent switching power supply units from 12W rated capacity and if there are dimmers a ventilation clearance of 1/2 module must be maintained with the spacers DS12 on both sides. Wide-range input voltage 88-264V AC (110V -20% up to 240V +10%). Efficiency 24V DC 87%. Stabilised output voltage ±1%, low residual ripple. Short-circuit proof. Overload protection and over-temperature switch-off by means of switching off with automatic switching-on after fault clearance (autorecovery function).
