05 February 2007 14:34
Wavre, Belgium – Cherokee International (NASDAQ: CHRK), a leading manufacturer of power supplies, has launched the world's most compact 850W 1U rectifier for telecom applications.
The unit features an unrivalled power density for those applications requesting small depths of enclosures, such as business premises equipment and street cabinets. This is a major factor in speeding up network deployment, and hence reducing total infrastructure costs.
This rectifier is the perfect candidate to power infrastructure equipment in both wireless (Wi-Max, BWA and UMTS), and wireline (xDSL) access networks. It supplies 850W in a volume of 86mm (3.4in) x 40.6mm (1.6in) x 220mm (8.66in), and a power density of 1162W/L or 19.2W/in³, making it the most power dense rectifier of its class.
The rectifier starts at -40°C / (-40°F) and operates at full specification from -20°C / (-4°F) to 70°C (158°F) with a smart power derating above 55°C / (131°F).
The full universal input range is up to 300V and worldwide approvals make it a perfect candidate to power global product platforms.
The unit is protected against over and undervoltages on the input and output. It features smart power derating and internal temperature protection. Units are hot-swap pluggable and fault-redundant.
Signals include mains detection, power good, current read-out, output programming, remote on / off capability, and active load-sharing without any additional module. CAN bus protocol is also available for extended system monitoring, and can control many more features.
The unit is in full-scale production and modules are available from stock
