2WR3 DC / DC series products provide small volume, high efficiency, small power, constant voltage, input isolation, non regulated, single output module power supply. This series of modules are specially designed for applications where a set of voltage isolated from the input power supply needs to be generated in the on-board power supply system. The product is suitable for pure digital circuit, general low-frequency analog circuit, relay driving circuit, data exchange circuit, etc.


Product Features 

1. Features: constant voltage input, isolated non regulated single output, 2W

2. Conversion efficiency 90% (typ)

3. Isolation is required between input and output (isolation voltage ≤ 1500vdc)

4. The voltage of the input power supply is relatively stable (voltage variation range ± 10% VIN)

5. Operating temperature range: -40°C~+85°C

6. Output short-circuit protection: Sustainable short-circuit protection and automatic recovery

7. Small sip package
