2W, Fixed input voltage, isolated & unregulated dual /single output cTOus C € Patent Protection RoHS FEATURES • Continuous short-circuit protection • Operating temperature range: -40C to +105°C • High efficiency up to 86% • High power density • Miniature SIP package • Isolation voltage: 3K VDC • No external component required • International standard pin-out E_S-2WR2 & F_S-2WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply system, They are suitable for 1. Where the voltage of the input power supply is stable (voltage variation: ±10%Vin); 2. Where isolation between input and output is necessary (isolation voltage ^3000VDC); 3. Where the output voltage regulation and the ripple & noise of the output voltage is not strictly required; 4, Typicd appiicaton: digit circuit condition; normal low-frequency official circuit conditon; relay chive circuit and data switching circuit conditon, etc. MORNSUN GUANGZHOU SCIENCC & TECHNOLOGY CO.,LTD.

Design Reference 1. Typical application If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.3. Moreover, choosing suitable filter capacitor is very important, start-up problems may be caused by too large capacitance. To ensured the modules running well, the recommended capacitive load values as shown in Table 1. Recommended capacitive load value table (Table 1) Note: #The capacitive loads of positive and negative outputs are the same.. 2. EMC typical recommended circu LDM Note: 1. 24V input series, is subject...
