DESIGN & APPLY CONSIDERATIONS

1) Requirement on output load

To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of the full load.

If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our

company

’s products with a lower rated output power (A_(X)T-W2 series).
