Original Press Release:
Cherokee Intl Intros First to Market 1U 2500 Watt Front End Rectifier
2500-Watt front end / rectifier packs 27 watts per cubic inch, customizable power platform design, and microprocessor control for powering datacom, telecom and industrial applications
Tustin, Calif., January 4, 2007 - Cherokee International (NASDAQ: CHRK), a leading manufacturer of power supplies, today announced its CAR2500 series of front end / rectifiers for network routers and switches, enterprise servers, telecommunications equipment, and industrial ATE applications. The CAR2500 is the only 1U, 2500 watt (W) power supply on the market with twice the power of 1U competitive units. The CAR2500 is designed as a customizable power platform--a flexible building block to satisfy specific OEM power applications. With an unprecedented power density of 27W per cubic inch and an efficiency of 92 percent, the new CAR2500 series is an unparalleled distributed-power-architecture solution.
This new platform is feature rich with more built-in intelligence and flexibility. An onboard microcontroller, equipped with a 10 bit analog-to-digital converter, allows for a far more accurate temperature, current, and voltage sensing capability. An automatic fan speed control regulates the internal supply temperature for increased reliability and audible noise control. The CAR2500 also offers greater flexibility by supporting many interfaces such as I2C, PMBus, and Ethernet protocols.
Measuring 1.61 by 4.00 by 14.25 inches, the CAR2500 front end / rectifier series delivers -54 volt direct current (VDC) at 46.3 amps (A) for high-line operations of 230 volt alternate current (VAC) with standby voltage of either 3.3V or 5V at 1A to power external housekeeping and monitoring circuitry. Narrow enough to fit up to four units side-by-side in a 1U power shelf, the CAR2500 series can supply up to 10,000W or 7,500W N+1 redundant power.
A thermally controlled fan enables -10 degrees Celsius (C) to +70C operation and also a -40C startup capability-ideal for uncontrolled environmental conditions such as outdoor telecom equipment, radio frequency (RF) amplifiers, and wireless applications. Additional features include hot-swap and fault redundancy, active single-wire load sharing, output voltage programming, current readout, remote on/off and front plate LEDs. Protection features on the rectifier include input over and under voltage, output over voltage, over temperature and over current.
The CAR2500 Series is currently offered in two models, the +48 volt output (CAR2548FP) and the -54 volt output (CAR2548TN) to support the most common DPA architectures, isolated and non-isolated. The +12 volt output (CAR2512FP) will be available soon.
A supporting system shelf, ACE254, is also available and fits in standard 19-inch telecom cabinets. The ACE254 rack comes in a 4-bay redundant, hot swap configuration offering scalability up to 10,000W. The universal rack supports the CAR2500 family of +48V and -54V output versions.
Pricing and Availability
The CAR2500 series is priced at $399 in OEM volumes. The ACE254 universal rack, which supports the 48V and -54V versions, is priced at $255 in OEM volumes. Samples are available now through Cherokee International.
