Keywords:RCL175? AC/DC switching power supply? XP Power?

XP Power has announced an AC/DC switching power supply that is said to enable users to specify any voltage level up to the maximum rating of each output. The RCL175 is available with one to four outputs: 3V to 60V on output one, 5V to 60V on output two, and 5V to 30V on outputs three and four. Outputs three and four are isolated, allowing parallel or series connection for further flexibility. Output one is user-adjustable by 10 percent and the other outputs track this by the same percentage. The compact power supply is approved for industrial, IT and medical applications, and is suited to both Class I and Class II use (with or without a ground connection).

The RCL175 is rated at up to 120W with convection cooling, 175W with 12cfm of forced-air cooling, and has a peak rating of 200W. Efficiencies range from 84-90 percent depending on output configuration.

The range is based on 18 standard models that can be modified, both electrically and mechanically, for individual applications. Mechanical options include open frame, U-channel, U-channel with cover and U-channel with fan cover. Molex or terminal block connectors can be provided. Open frame models measure 140-by-94.1-by-32.6mm) and 500g.

The product uses a silicon carbide diode to maximize efficiency and minimize component count in the power-factor-correction boost converter. Fractional turn technology in the transformer is also said to enhance efficiency and reduce component count, allowing combinations of outputs such as 3.3V and 5V without the need for post-regulation. The topology facilitates the use of low voltage Schottky rectifiers in the output stages.

The product is available now priced from $155 each for 100+ quantities.
