Front End/Rectifier Touts High Frequency at Light Loads
Cherokee International announced its 2,500W CAR2512 front end intended for low profile, 12V distributed power architecture applications such as high-performance enterprise and service-provider switches and routers, mid- to high-end servers and storage equipment. Packaged in a small, 1U-high footprint and measuring 1.6" × 4" × 14.88", the CAR2512 offers a power density of 25W per cubic inch. It provides 208A, supporting 12V bus architectures that power point-of-load (POL) converters. According to the company, it can achieve 90 percent efficiency at 20 percent of load, with a peak efficiency of 91.5 percent. Protection features on the rectifier include input over and under voltage, output over voltage, over temperature and over current. In addition, a microprocessor-based design allows for automatic fan speed control, which can be used to optimize noise levels of sensitive office-environment applications. This model is also available with full I2C communications, providing intelligent monitoring and control of critical parameters. The CAR2512 is priced at $395 in OEM quantities.
