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.

Note:
1. If the product is operated under the min. required load, the product perfor-
mance cannot be guaranteed to comply with all performance indexes in this
datasheet;
2. The max. capacitive load should be tested within the input voltage range and
under full load conditions;
3. Unless otherwise specified, data in this data sheet should be tested under the
conditions of Ta=25°C, humidity<75% when inputting nominal voltage and
outputting rated load;
4. All index testing methods in this datasheet are based on our Company’s
corporate standards;
5. The performance indexes of the product models listed in this manual are as
above, but some indexes of non-standard model products will exceed the
above-mentioned requirements, and please directly contact our technicians
for specific information;
