Switchable dual input voltage: AC 110V/220V. Wide input voltage range, stable and accurate output voltage. Protection: short circuit, overload, overvoltage CE and RoHS compliant safety, high efficiency and stable performance. Widely used as a power adapter for LED strips, LED displays, display equipment, industrial equipment, etc. Due to the reactive power often present in LED lights, transformers should always be selected about 30-40% larger! Usually, the transformer always has a power loss of 20%. Never exceed the maximum connected load. Suitable for most DC 12V devices such as LED lights, LED strips Not waterproof Circuit protection: overvoltage and short circuit LED indicator for ignition Energy efficiency class A+ Operating temperature and humidity: -10°C to +60°C 20% to 90% relative humidity Material: aluminum
