PSUP350 Series

The PSUP350 series of AC DC power supplies offers 300W with free air convection and 350W with 10.5CFM forced air. These supplies are housed in a low-profile 9.09 x 4.0 x 1.50 inch U-chassis frame. These supplies have a 90~264VAC (127~370VDC) input voltage range and provide single outputs ranging from 12VDC to 48VDC. Standard features include active power-factor-correction, remote on/off, remote voltage sense, power OK signal, and comprehensive over voltage, short circuit, over load, and over temp. protection. There are two different output connector options available for this series (Type C and Type T). All models are RoHS compliant and have UL/cUL, TUV, CE, and CB approvals.

  1. Derating may be needed under low input voltages. Please check the derating curve for more details.

  2. The power supply is considered a component which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

  3. There are two mechanical options available (Type C or Type T). Please see mechanical drawings for more details.

  4. The output power and output current listed on the "Models" tab is with 10.5CFM forced airflow. See data sheet for convection cooling specifications.
