The unit is housed in a space-saving shell and combines low cost with high perfomance across all line and load conditions. A ± 10% output trim feature is provided, allowing the user to compensate for long line lengths. The WF30R Series is assembled by a fully automated process using surface mount components for increased reliability. The converter’s rugged, low-profile, aluminium housing provides excellent EMI/ RFI shielding. Other features include: • Full Regulation Down to Zero Load • Under Voltage Lock-Out, Auto-Start • Internal Temperature Shutdown, Auto-Reset • Soft Start • Remote On/Off (Available in Positive or Negative Logic) • Remote Sense (Available in Single Outputs) • Over Current Protection • Output Over Voltage Protection • Output Voltage Adjust AGENCY APPROVALS PENDING Internet: http://www.cdpowerelectronics.com Power Electronics Division, United States 3400 E Britannia Drive, Tucson, Arizona 85706 Phone: 800.547.2537 Fax: 520.770.9369 WF30R 12/98 REV A Power Electronics Division, Europe C&D Technologies (Power Electronics) Ltd. 132 Shannon Industrial Estate, Shannon, Co.
