Information

B_S-1WR3 series is a small size, high-efficiency micro power, constant voltage, input isolation and unregulated, single output DC/DC power supply module provided by Hi-link to customers; this series of products are specially designed for the needs of on-board power supply systems. Designed for applications that generate a set of voltages isolated from the input power supply.

This product is suitable for:

The voltage of the input power supply is relatively stable (voltage variation range ±10%Vin);

Isolation is required between input and output (isolation voltage≤1500VDC);

The requirements for output voltage stability are not high;

Typical applications: pure digital circuits, general low-frequency analog circuits, relay drive circuits, data exchange circuits, etc.
