1 The maximum power value equals the standard output voltage multiplied by the maximum output current. 2 The standard output voltage depends upon each product. The output voltage in the normal condition is distributed over the upper limit side within the output voltage stability range (other than CE-0926, CE-0931). Output voltage setting method If there is a difference from the required output voltage, substitute an absolute value of the required output voltage into Vo in one of the following equations to calculate Rex and then install the product between the connected terminals.

Unit: V,k 3 Output voltage total variation (%) is a regulation including a load variation, an input variation, and a temperature variation, compared with the output voltage stability value. 4 The output side (lo2) of the output model should be used within the range of the operating area shown below.
PRECAUTIONS * When a choke coil is connected between the input-side power supply and the terminal 2, it should be of 4.7H max. Otherwise, an output ripple may be increased. * When the input-side power supply has a high ripple voltage or when it is required to reduce the ripple returning from the converter to the input, connect a capacitor having an appropriate capacity. * To normally start the converter, the rise time of the input voltage must be 40ms max. In other words, it is required to limit the time to 40ms between the time points of exceeding a 0.5V input voltage and going-up to the predetermined input voltage range. * Parallel operation to increase output current is not possible. * Cleaning of this product is inhibited. * Less-residue or non-cleaning type flux should be used so as to omit the cleaning.
