SAB0529

With the digital timer SAB0529,delay times between 1 second and 31 1/2 hours can be set.Time base is the 50Hz line frequency.A triac triggered by the SAB0529 IC.This can be programmed to two operating modes:"momentary switching" and "switch-off delay"(according to SIN 46120).

Features of the SAB0529 are:(1)direct operation from AC line or DC supply possible;(2)time base is 50 Hz line frequency;(3)triac triggering with voltage synchronization for resistive loads,or with current synchronization for resistive,inductive and capacitive loads;(4)triac gate trigger current up to 100mA;(5)continuous output current to relay actuation max. 100mA;(6)8 overlapping timing periods between 1 second and 31 1/2 hours;(7)2 operating modes;(8)ipon request,delay times can be adjusted to customer's specification,requiring only minimum external components..

The absolute maximum ratings of the SAB0529 can be summarized as:(1):the parameter is supply voltage at impressed dc voltage,the symbol is VS,the min is -0.3,the max is 5.5,the unit is V;(2):the parameter is current at TS,the symbol is ITS,the min is -4,the max is 4,the unit is mA;(3):the parameter is voltage at T,the symbol is VT,the min is -0.3,the max is 7.5,the unit is V;(4):the parameter is voltage at D,E,F,G,H,I,the symbol is V,the min is -0.3,the max is 7.5,the unit is V;(5):the parameter is short-term peak current at N,the symbol is INP,the min is -350,the max is 350,the unit is mA;(6):the parameter is junction temperature,the symbol is Tj,the max is 150,the unit is ;(7):the parameter is storage temperature,the symbol is Tstg,the min is -55,the max is 125,the unit is ;(8):the parameter is thermal resistance system-air,the symbol is Rth SA,the max is 70,the unit is k/W.
