The MDR-60-24 (Planet PWR-60-24) DC Single Output Industrial DIN Rail Power Supply Unit provides short circuit/overload/over voltage and over temperature protections for the stable operation of Industrial Ethernet equipment. As they adopt the free air convection cooling system, they are able to operate under the temperature ranging from -20 to 70 degrees C (maximum). Thus, the DC single output industrial DIN rail power supply units can be placed in almost any difficult environments.
