B_S-1WR3 series --- is a small-volume, high-efficiency, micro-power, fixed-voltage, input-isolated, non-regulated, single-output DC/DC module power supply provided by Hailingke for customers; this series of products is specially designed for applications in on-board power supply systems that need to generate a voltage isolated from the input power supply. This product is suitable for:
The input power supply voltage is relatively stable (voltage variation range ±10% Vin);
Isolation is required between input and output (isolation voltage ≤ 1500VDC);
The requirement for output voltage stability is not high;
Typical applications: pure digital circuit occasions, general low-frequency analog circuit occasions, relay drive circuits, data exchange circuit occasions, etc.
