REPETITIVE OVERLOAD CURVE MEETING NEMA STANDARDS FOR General Purpose Rectifier Equipments Under 100 KW AT 40C AMBIENT NOTES: 1. The repetitive overload calculation procedure outlined on the back cover was used to obtain the ratings shown by curve 16. This method can be used when the rectifier diode is mounted on any heat sink possessing: a) a heat dissipation surface of 100 square inches or more, b) a thermal capacity greater than 700 watt-seconds; and, c) a fin efficiency greater than 95% for free convection and 85% for forced air cooling. 2. The NEMA standard cited in curve 16 specifies 200% output current for 10 seconds and 150% output for one minute. OUTLINE DRAWING TABLE OF DIMENSIONS Conversion Table SYM.

INSTALLATION INSTRUCTIONS Following these installation instructions will result in a diode-to-heatsink thermal resistance of .10C/watt or less. 1. Be sure mounting surface is clean and flat at (.001 inch/inch). 2. Mounting hole diameter should not exceed rectifier stud OD by more than 1/16 and should be deburred. 3. Use Dow Cornings DC3, 4, 340 or 640 or GE6332L or equivalent on mounting surfaces which come in contact with the heatsink. 4, Use suitable hardware. (Nut and split lockwasher are supplied.) 5. Tighten with a torque wrench, from nut side to 100 lb-in. 575REPETITIVE OVERLOAD RATING DETERMINATION FOR OVERLOAD CONDITIONS OTHER THAN SHOWN IN FIGURE 16 To determine the steady state current rating which will accommodate a given repetitive overload rating (for diode mounted on a 7 X 7 x 3/8 aluminum or 7 x 7 x 1/4 copper fin) the following cut and try method is suggested: Ty max. = Ta + (Pss) Rosa + (Poi-Pss) Zot) Ty max. = Max. Junction Temperature (200C) Ta = Max. Ambient in C Psgg = Steady State Diode Power Dissipa- tion from curve 3 (reverse losses ignored). Rya = Steady State Thermal Resistance from curve 11. Pot = Diode Power Dissipation (under re- petitive overload conditions) from curve 4. Z(t) = Transient Thermal Impedance (under overload conditions) from curve 11. where As a starting point, it is suggested that the steady state diode current without repetitive overload current be deter- mined (see curves 12, 13, or 14). To permit a repetitive overload rating, the maximum rated diode current must be reduced. Using a reduced value of steady state current as an estimate, the data for insertion into the formula can be obtained from curves 3, 4 and 11. When the estimate is correct, the right side of the formula given above will equal the maximum Ty, which is 200C. 200% repetitive overload required for 10 seconds; 3-phase bridge; convection cooled; maximum ambient = 30C. Example: From curve 13, steady state rating without provision for repetitive overload equals 56 amps/diode. Therefore, a first approximation may be 40 amps steady state and 80 amps overload. Substituting these values in the formula, we have: Ty max. = 30 + (40 x 2.55) + (97 40) .75 Ty max. = 175C The answer of 175C indicates that our steady state selec- tion was slightly low. By choosing 45 amps steady state and 90 amps overload, we come closer to the maximum rating permissible, based on Ty max. = 200C. Of course, the 3-phase-bridge output current will be three times the diode current, 135 amps average steady state, and 270 amps, or 200% current, for 10 seconds. 576
