Cherokee Intros 1U 2500 Watt Front End/Rectifier
Rack-mountable front end/rectifier.
Tustin, CA — Cherokee International has introduced its CAR2500 series of front end rectifiers for network routers and switches, enterprise servers, telecommunications equipment, and industrial ATE applications. According to the company, the CAR2500 is the only 1U, 2500 watt (W) power supply on the market with twice the power of 1U competitive units. The product is designed as a customizable power platform — a flexible building block to satisfy specific OEM power applications. The new rectifiers have a power density of 27W per cubic inch and an efficiency of 92 percent. 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 unit also offers greater flexibility by supporting many interfaces such as I2C, PMBus, and Ethernet protocols.
The rectifier measures 1.61 x 4.00 x 14.25-in., delivers -54VDC at 46.3 amps for high-line operations of 230VAC 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 can supply up to 10,000W or 7,500W N+1 redundant power.
A thermally controlled fan enables -10° to +70°C operation and also a -40°C startup capability — especially suitable 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 units are currently offered in two models: the +48V output (CAR2548FP) and the -54V output (CAR2548TN) to support the most common DPA architectures, isolated and non-isolated. The +12V output (CAR2512FP) will be available soon.
A supporting system shelf, ACE254, is also available and fits in standard 19-in. 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.
