Cherokee International Unveils Its Ultra-High-Density CAR1248 Front End / Rectifier
1200-Watt front end / rectifier packs 19 watts per cubic inch
Tustin, Calif., September 30, 2004 - Continuing its innovation in power density, Cherokee International, a leading manufacturer of power supplies, today announced its CAR1248 front end / rectifier intended for low profile, distributed power architecture applications. Packaged in a small, 1U-high footprint and measuring 1.65 by 3.44 by 11.2 inches, the CAR1248 front end / rectifier provides best-in-class power density of 19 watts (W) per cubic inch. The CAR1248 delivers a 48 volt (V) single output at 25 amps (A) intended to be used as a regulated bus along with a 5V standby voltage to power external housekeeping and monitoring circuitry. With leading edge power density, the CAR front end / rectifier is narrow enough to fit up to five units in a power shelf - supplying up to 4800W N+1 redundant or 6000W.
The CAR1248 is ideal for design engineers faced with high power requirements in constrained spaces such as low to mid servers, enterprise networking, power over Ethernet (POE), and automatic test equipment applications.
"As our customers' end equipment becomes more sophisticated with greater performance and features, the power demanded from internal microprocessors within the equipment is increasing at the expense of available room for power," said Mike Wagner, vice president of marketing for Cherokee International. "Our 1U CAR1248 illustrates an example of our execution from our product road map demonstrating Cherokee International's commitment to providing best-in-class power densities with competitive value."
The wide-range, universal-input CAR1248 comes with integrated redundant diodes and a thermally controlled fan enabling -25 degrees Celsius (C) to +70C operation and -40C startup capability - ideal for 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.
An accompanying racking system, the ACE125, offers system scalability accommodating up to five modules (6000W) or 4800W in a redundant, hot-swap configuration. The full featured ACE125 rack, providing 4800W, comes equipped with a low voltage disconnect (LVD) and controller with universal power-monitoring functions and a comprehensive set of alarms and status indicators for the exchange of system-monitoring data with the end user. The basic version of the rack is offered without the monitoring control and LVD features, which allows room for an additional CAR1248 module for a total of 6000W. The CAR1248 also comes with an I2C serial interface, which enables monitoring of various operating parameters within the unit. Digital features include voltage programming, current limit adjustment, thermal warning, remote on/off, and AC/DC good and fault signals. Later this year, a 12V / 1250W rectifier model is expected to follow the release of the 48V version.
Pricing and Availability
The CAR1248 modules are priced at $250 in OEM quantities. Samples and low order quantities are available from stock.
