B_T-3W series is designed for application where an isolated voltage is required in a distributed power supply system.It is suitable for
1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2.Where isolation is necessary between input and output (isolation voltage ≤1500VDC);
3.Where do not has high requirement of line regulation , load regulation and the ripple & noise of the output voltage;
Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits .
