The device is used in the initiation of electric detonatorsused in mining, industry, civil engineering and forestry. Itcontains a three-positioned switch (1) for the modes of charging,blasting and discharging. The generator has an induction feedback.Its stepping up winding across a voltage multiplier (8) isconnected to a charging capacitor (9) and across a limitingimpedance (10) to one of the output terminals (11). Through thefirst contact couple supply is delivered to the generator, a lightindicator (15), reference source (16) and two electrolytecapacitors (18, 27) are charged across two diodes. The anode ofdiode (21) is connected to the generator the cathode of which iscoupled, together with the second lead of the light indicator (15)to the output of comparator (22) the noninverting input of whichis connected to the output of the reference source (16). Itsinverting input across filter (23) is connected to the output of avoltage divider (24) the input of which is coupled to the chargingcapacitor (9). The two output terminals are connected to neuteracross electronic switches (19, 26), connected across the secondand the third contact couples, respectively, of reswitch (1) ofthe voltage of the electrolyte capacitors (18, 27).1 claim, 1 figure/!
