The 1S7E_1.5UP series is 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 is necessary between input and output
(isolation voltage ≤1500VDC)

3) Where the regulation of the output voltage and the output ripple noise
are not demanding

Such as: purely digital circuits, ordinary low frequency analog circuits, and data
switching circuits.

1S7E_1.5UP Series

1W - Dual/Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated

Typical application

If it is required to further reduce input and output ripple, a lter capacitor
can be connected to the input and output terminals, see Fig. 1.
Moreover, choosing a suitable lter capacitor is very important, start-up
problems may be caused by too large capacitance. To ensure the modu­les are running well, see the recommended capacitive load values as
shown in Table 1.

Output load requirements

In order to ensure the converter can work reliably with high eciency,
the minimum load should not less than 10% rated load when it is used. If
the needed power is indeed small, please parallel a resistor on t the out­put side (The sum of the ecient power and resistor consumption power
is not less than 10%).
