= 0.7 X DC AMPS

= DC AMPS
1.6 TO 1.8 X DC AMPS

FOR EXAMPLE, IN A FULL WAVE BRIDGE CIRCUIT WITH A CAPACITIVE FILTER, IF THE LOAD IS 1 AMP DC, THE RMS SECONDARY CURRENT IS 1.6 TO 1.8 AMP RMS.

ONLY PRIME RAW MATERIALS ARE USED. HIPOT RATING OF 1500 V RMS IS STANDARD. ELECTRICAL RATING HAVE CHOSEN TO COVER A WIDE RANGE OF APPLICATIONS. ALL TRANSFORMERS HAVE TWO CENTER-TAPPED SECONDARY WINDING, WHICH MAY BE SERIES OR PARALLEL CONNECTED AS INDICATED IN RATING CHART. THE SECONDARY CURRENT SHOWN IN THE TABLES ARE RMS RATINGS. DEPENDING UPON RECTIFIER CIRCUIT CONFIGURATIONS, THE RMS SECONDARY CURRENT IS DIFFERENT THAN THE DC OUTPUT CURRENT. THIS IS INDICATED IN THE CHART BELOW:

THIS MEANS THAT THE TRANSFORMER NO LOAD VOLTAGE WILL BE % MORE THAN RATED FULL LOAD VOLTAGE.
