Silicon A3512 SERIES Rectifier Stacks High Conversion Efficiency Up to 99% in certain applications. Excellent Regulation Forward voltage drops of less than one volt per cell. Low Reverse Current Excellent for magnetic ampli- fier applications. Wide Range of Operating and Storage Temperatures Will operate from 65C to 175C. No Aging Extremely long life no transformer taps required high reliability. Rugged Construction Meets stringent military en- vironmental tests. Small Size Greatly reduces space and weight re- quirements. fo Complete Packaged Rectifier Circuit Requires only mounting bolts and electrical connections. No special fin design or insulating hardware. Dependability Backed by a General Electric one year written warranty. Versatility 171 stacked combinations with DC out- puts up to 108 amperes to meet a variety of circuit conditions. Special circuits can be designed to your order. 637> Ww z 200% = < SINGLE FIN 3 180% = w - i 500 uw = MAXIMUM ALLOWABLE NON~RECURRENT 2 160% j SURGE CURRENT AT RATED LOAD 2 fo 5 CONDITIONS. 8 5 ooo / Ww D, x = 140% Se a 3 ay a o 200 = s, fo PD Z 120% tS 300 5 ee IN NA 9 a & w q S ft On, Z 100% Keep, PIN 5 p~ fe On N\ y 200 4 = >< N\ 5 FOR SUB-CYCLE SURGE CURATION, | 3 SN NO (LESS THAN I CYCLE) USE I2t 80% < 2 RATING (CHART NO. 5) | ~_] 2 MN \ z 100 5 NJ N % aw a 60% p a wi & NI <a = 40% + - ApS. \ 2 4 6 8 10 20 40 60 4 (FORCED AIR AND ELEVATED TEWP CYCLES AT 60 CPS E RATINGS AT MAXIMUM VOLTAGE NOTE a 20% RESISTIVE OR INDUCTIVE \ WHEN FINS ARE OPERATED Qo 4 & LOAD AT SEA LEVEL RATING BY 10% PER FIN . | | | 20 40 60 80 100 120 i40 160 180 Cc HART N Oo. 4 AMBIENT TEMPERATURE IN C 500 soo CHART NO. 1 | | | 200 coat 8 IS MIN.
