The 2S7A Series is specially designed for applications where a group of
polar power supplies are isolated from the input power supply in a dis-
tributed power supply system on a circuit board.
These products apply to:
1)Where the voltage of the input power supply is fixed
(voltage variation ≤±±5)ꢀ
2)Where isolation is necessary between input and output
(isolation voltage ≤1000VDC)ꢀ
No Heat Sink Required
3)Where the regulation of the output voltage and the output ripple
and noise are demanded.

Note:
1. Operation under minimum load will not damage the converterꢀ However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=2±°C, humidity<7±5, nominal input voltage
and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate
standards.
4. Only typical models listed, other models may be different, please contact our
technical person for more details.
