Sub-distributions. It delivers an output power of 10-100 W, complies with ErP efficiency guidelines, and is powered via a wide-range input (85-264 V AC). 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 the 10 W devices) feature adjustable outputs. The DRL series has a Class II construction (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.
