Cherokee's High Power Density Rectifier Provides 1500W in a 1.6U Package
08 May 2003
Cherokee International expands its CAR Rectifier Series to include a 2U rack-mount front-end rectifier.
Cherokee International, a leading manufacturer of switch-mode power supplies has expanded its CAR Rectifier series – with the launch of the CAR1548 rectifier system. The power level and shape factor has been chosen to offer the perfect fit to most cellular networks offering low initial investment with superior system dimensioning capabilities for either 1.6U or 3U rack systems. The rectifier is also a superior solution to many distributed power architectures such as used in today’s optical routing and switching, data storage, enterprise networks, broadband and applications where a highly reliable bulk power supply is required.
With industry trends moving toward lower profiles, the CAR1548 rectifier packs 1500W of constant power in compact dimensions of 69mmH x 128mmW x 325mmD, providing 31.2A at 48V, Power Factor Corrected with typical efficiency of 91%.
The wide range universal input CAR1548 comes with integrated redundancy diodes and a thermally controlled fan enabling operation from –40°C to 70°C, ideal for wireless applications. Additional features include hot swap capability, fault redundancy, active 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 over current and smart power derating.
The CAR1548 rectifier modules are available with the ACE15 racking system offering greater flexibility and scalability. Cherokee’s ACE15 rack is available with three CAR1548 modules mounted horizontally in the 19” 2U rack providing 4.5kW, the second houses six modules mounted vertically in a 19” 3U rack providing 9kW.
The fully featured ACE15 rack 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. System control is available through one of three methods: a basic analog function, the new digital “can bus” or 12C bus interface – each permitting the monitoring of vital parameters on demand by a host system or computer. A basic version of the rack is also offered, without the monitoring control and LVD features.
