New Products Dec 04, 2003 by Jeff Shepard

Cherokee International LLC (Tustin, CA), a manufacturer of switch-mode power supplies, announced a low-profile, 1U version of its CAR rectifier series for telecom and networking devices. The new CAR0548 rectifier delivers 500W and is designed to deliver bulk power to distributed power architectures and dc/dc systems used in optical routing equipment, enterprise networks and wireless applications.

Measuring 1.59in x 3.38in x 10.19in, the CAR0548 provides 9W/in³ at a typical efficiency of 85%. The new CAR rectifier comes in two versions: offering 10.4A at +48V as a front-end power supply, or 9.25A at -54V when used for telecom and battery-charging applications. The wide-range, universal-input CAR0548 comes with integrated redundant diodes and a thermally controlled fan enabling operation from -40°C to +70°C, suitable for uncontrolled environments such as wireless applications.

Additional features include hot-swap capability; fault redundancy; active load sharing; output-voltage programming; current readout; remote on/off; front-plate LEDs; and input over-voltage and under-voltage, output over-voltage, over-temperature, and over-current protection. Additionally, an accompanying racking system, the ACE05 rack, comes in a four-module, redundant, hot-swap configuration offering flexibility and scalability to 2,000W.

The CAR0548 modules are priced at $275 in OEM quantities. Samples and low-order quantities are available from stock.
