Corporate: www.cdtechno.com Product: www.cdpowerelectronics.com WPN20R 20 Watt Regulated DC/DC Converter Operating Temperature Range: -40°C to +100°C Industry Standard Pinout Input and Output Filtering Low Profile Shell Single and Dual Outputs High Efficiency Remote On/Off Function Output Trim Function Zero Load Operation EN 60950, UL1950, C-UL, VDE Agency Approvals The WPN20R series is a family of high performance DC/DC converters available in three input voltage ranges of 9-18V, 18-36V and 33-75V. The unit is housed in a space saving aluminum shell and combines low cost with high performance across all line and load conditions. The 300KHz switching frequency and forward converter topology provide excellent performance across all line and load conditions in a space saving package. Other features include: full regulation down to zero load, under voltage lock-out, internal temperature shutdown, soft start, remote on/off and over current protection. An output trim feature is provided, allowing the user to compensate for long line lengths. The WPN20R Series is assembled using a fully automated process incorporating 100% surface mounted components for increased reliability. Applications include: Telecommunications, Battery Powered Sytems, Process Control Equipment, Transportation Equipment and Distributed Power Systems.
