Cherokee Unveils CAR1248 Front-End Rectifier

Cherokee International LLC (Tustin, CA), a manufacturer of switch-mode power supplies, announced its new CAR1248 front-end/rectifier intended for low-profile, distributed power architecture applications. The CAR1248 is suitable for high power requirements in constrained spaces such as low-to-mid servers, enterprise networking, Power-over-Ethernet, and automatic test equipment applications.

The CAR1248 front-end/rectifier provides power density of 19 W/in³. The CAR1248 delivers a 48 V single output at 25 A intended to be used as a regulated bus along with a 5 V standby voltage to power external housekeeping and monitoring circuitry. The CAR front-end/rectifier is narrow enough to fit up to five units in a power shelf — supplying up to 4,800 W N+1 redundant, or 6,000 W.

The wide-range, universal-input CAR1248 comes with integrated redundant diodes and a thermally controlled fan enabling -25 °C to +70 °C operation and -40 °C startup capability. 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-voltage and under-voltage, output over-voltage, over-temperature and over-current. The CAR1248 also comes with an I2C serial interface, which enables monitoring of various operating parameters within the unit

Packaged in a small, 1U-high footprint and measuring 1.65 in x 3.44 in x 11.2 in, the CAR1248 front-end/rectifier modules are priced at $250 in OEM quantities. Samples and low order quantities are available from stock. Later this year, a 12 V/1,250 W rectifier model is expected to follow the release of the 48 V version.
