These products apply to: 1) W here the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) W here isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) W here the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. 12 10.8-13.2 15 13.5-16.5 24 21.6-26.4 UL UL UL UL UL CE UL CE UL CE UL CE MODEL SELECTION A0505S-1W P acka ge S tyl e O u tp ut Vo lta g e Inpu t Volta ge P rod uct S erie s Note: The A_S-W2/B_LS-W2 series also are available in our company.

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. Recommended circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 1).
