(1) Protection provided by limiting the transient voltage to 2 Uc max
Maximum reduction of transient voltage peaks
Slight increase in drop out time (1.1 to 1.5 times the normal time)
(2) No overvoltage or oscillating frequency
Polarised component
Slight increase in drop out time (1.1 to 1.5 times the normal time)
(3) Protection by limiting the transient voltage to 3 Uc max, and limitation of oscillating frequency
Slight increase in drop out time (1.2 to 2 times the normal time)
