Note:(1) A minimum 10% load is required on the output to meet the published specifications. Even though working at no
load condition will not damage the device, it is not adoptable.
(2) If the output power needed is smaller than rated, please connect a proper value resistor at output end in parallel
to increase the load or contact us for a lower power product.
(3) For lower noise and ripple, please connect a “LC” filter at the output. The capacitance must be at proper value in
case of start-up problems.
