Note	1. Unless otherwise specified, all specification parameters are measured under the input of 24VDC, rated load, and an ambient temperature of 25℃. 2. The power supply should be regarded as a part of the system components. All EMC tests will be conducted by installing the sample on a 1mm thick, 360mm long * 360mm wide metal iron plate. The power supply needs to be combined with the terminal equipment for relevant electromagnetic compatibility confirmation. 3. When the altitude exceeds 2000 meters (6500 feet), the ambient temperature of the fanless model decreases at a rate of 3.5℃ per 1000 meters, while the ambient temperature of the fan-equipped model decreases at a rate of 5℃ per 1000 meters.
