Note 1: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 2: For applications requiring 2,250V of isolation, order module with V option (see ordering information on last page of this datasheet).
Note 3: Higher values of isolation capacitance can be added external to the module.
