12V Isolated Dual Output DC DC Converter 15VDC 24VDC 1W Fixed Input Unregulated
1W DC DC converter Fixed input voltage, isolated & unregulated dual output
Description
A_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 is not strictly required;
4. Typical application:preceding-stage interference isolation condition;ground-interference canceled condition;digit circuit condition; Voltage-isolation converting condition;normal low-frequency artificial circuit condition;relay drive circuit condition,etc.
