The 1S4A_1.5UP series are specially designed for applications where an isolated
voltage is required in a distributed power supply system.
These products apply to:
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.
Typical application: digit circuit condition; normal low-frequency artificial circuit
condition; relay drive circuit and data switching circuit condition, etc.
