Sub-distributions. It provides an output power of 10 to 100 W, meets the ErP efficiency guidelines, and is powered via a wide-range AC input (85-264 V). All four power classes are available with a nominal output voltage of 24 VDC, and there are also 12 V DC models with output powers of 10, 30, and 60 W. All models (except for the 10 W devices) have adjustable outputs. The DRL series features a Class II design (protective insulation) and therefore does not require a protective conductor. The test voltage between input and output is 3 kV AC. All models are convection-cooled and designed for operating temperatures between -20°C and +71°C. Additionally, the series is equipped with long-life electrolytic capacitors.
