Product Details
1W isolated DC-DC converter Fixed input voltage, unregulated single output
Description
B_XT-1WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply system.They are suitable for
1. Where the voltage of the input power supply is stable(voltage variation:±10%Vin);
2. Where isolation between input and output is necessary(isolation voltage≤1500VDC);
3. Where the output voltage regulation and the ripple&noise of the output voltage is not strictly required;
4. Typical application:digit circuit condition;normal low-frequency artificial circuit condition;relay drive circuit condition, etc.
