YLPTEC B1212S-2WR3

The B_S - 2WR3 series is a compact, high-efficiency, miniature-power, fixed-voltage-input, isolated unregulated, single-output DC/DC module power supply, specifically designed for on-board power systems requiring a voltage rail isolated from the input supply. It is suitable for applications where the input supply voltage is relatively stable (voltage variation range ±10%Vin), isolation between input and output is required (isolation voltage ≤1500VDC), and output voltage regulation is not critical. Typical applications include pure digital circuits, general low-frequency analog circuits, relay driver circuits, data switching circuits, and similar use cases.
