1W, Fixed input voltage, isolated & unregulated

dual/single output

FEATURES

Subminiature SIP package

Operating temperature range: -40℃ to +105℃

Efficiency up to80%

Isolation voltage: 1.5K VDC

High power density

No external component required

International standard pin-out

A_S-1WR2 & B_LS-1WR2 series is specially designed for applications where an isolated voltage is required in a distributed power supply

system. It is suitable for:

1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);

2.Where isolation is necessary between input and output (isolation voltage ≤1500VDC);

3.Where do not has high requirement of line regulation and load regulation;

4. Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.
