Product Details
3W DC DC converter module fixed input voltage, isolated & unregulated single output
Description
B_S-3WR2 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.
FEATURES
Operating temperature range: -40℃ to +85℃
Ultra Compact SIP package
Isolation voltage: 1.5K VDC
High power density
No external component required
International standard pin-out
