WRE_S-1WR2 - 1

1W, Wide input voltage, isolated & regulated output DC/DC converter V' 'V Patent Protection RoHS C€ FEATURES • Ultra compact SIP package • Wide input voltage range (2:1) • Operating temperature range: -40C to +85 C • Isolation voltage: 3.0K VDC • High power density • Short circuit protection (self-recovery) • Remote On/Off • EN60950 approval WRE_S-1WR2 & WRF_S-1WR2 series are isolated W DC-DC products with 2:i input voltage and conventional voltage output. The product has a relatively compact SIP plastic package,, and features high efficiency, operating temperature of -40 °C~+85 C. The smaller size and fine cost design make the converter an ideal solution in communication, instruments, and industrial electronics applications. Selection Guide Notes: ©Exceeding the maximum input voltage may cause permanent damage; ©For the dual output modules, the capacitive loads of positive and negative outputs are the same.

Design Reference 1. Recommended circuit All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery. If a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin1, Cin2, Cs and Cout; or select capacitors of low equivalent impedance like series capacitor, etc. Cs is used to reduce ripple. No need to add Cs, if ripple meets the demand .Appropriate filter capacitance shall be chosen, start-up problems may be caused if the capacitance is too large. For each output...

DC/DC Converter WRE_S - 1WR2 & WRF_S-1WR2 Series 3. Ctrl end The modules are of normal output when the Ctrl end is suspended or of high resistance; the modules turn off when connecting with high level (relative to the input grounding); notice that the current flows into the pin shall be 5 - 10mA, the modules will be permanently damaged if the current exceeds its max. value (20mA in general). The value of R can be derived as follows: V - V - 1 .0 R= C D - 300 IC For Detailed parameter, please refer to EMC solution-recommended circuit in this manual. Input Current(A) When the electricity is...

DC/DC Converter WRE_S - 1WR2 & WRF_S-1WR2 Series Notes: 1. Packing information please refer to Product Packing Information which can be downloaded from www.mornsun-power.com. Packing bag number: 58210004; 2. Recommend to use module with more than 5% load, if not, the ripple of the product may exceeds the specification, but does not affect the reliability of the product; 3. The recommended unbalance degree of the dual output module load is ≤±5%; if the degree exceeds ±5%, than the product performance cannot be guaranteed to comply with all parameters in the datasheet. Please contact our...
