Compact Size with more Practicability and Convenience The PWR series for industrial Ethernet devices is specially designed for the harsh working environment where sometimes it is hard to find suitable DC voltage power source. The PWR series are DC single output industrial DIN rail power supply units, which accept universal 85-264 AC input voltage (277VAC operational) and provides 12VDC power output with 15 watts. The compact size design can be installed on DIN rail TS-35 / 7.5 or 15. It is an ideal and convenient DC power feeding solution for industrial equipment under heavy conditions. Stable Performance under Difficult Environments The DC Single Output Industrial DIN Rail Power Supply Units provides various models with 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 rang of -30 to 70 degrees C (maximum). Thus, the DC single output industrial DIN rail power supply units can be placed in almost any environment.
