Typ. Max. Units Switching frequency 300 kHz Max capacitive load 550 mF/A MTTF per ML-HDBK-217 Ground benign Circuit stress method TA = +25º unmodified database 1.4 MHr FEATURES RoHS compliant Operating temperature range: -40ºC to +100ºC Industry standard pinout Input and output filtering Low profile shell Single and dual outputs Output trim function DESCRIPTION The WPN20RC series is available in three input voltage ranges of 9-18V, 18-36V and 33-75V. The unit is housed in a space saving aluminum shell. The 300KHz switching frequency and forward converter topology provide excellent performance across all line and load conditions. Other features include: under voltage lock-out, internal tem- perature shutdown, soft start and over current protection. An output trim feature is provided, allowing the user to compensate for long line lengths. Applications include: Telecommunications, Battery Powered Sytems, Process Control Equipment, Transportation Equipment and Distributed Power Systems. The product range has been recognised by Under- writers Laboratory (UL) to UL 1950 for operational insulation, file number E179522 applies. All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified. |
