DESIGN 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.
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to add a circuit
breaker to the circuit.
