2.Principal
MZ11 B series PTC thermister is a kind of compound
element which Rt of PTC thermistor is in series of Rv of
varistor.when turn on the switch, voltage is higher than
Rv’s varistor voltage, Rv is in conduction state, it’s proceed
of preheating startup is basically independent completed by
Rt, the startup spot of lamp pipe is in normal operating state,
voltage declines below the Rv’s varistor voltage, Rv is on
break-open state, then make zero power-consumption and
zero temperature-up comes true.
Selection of M2 11B series is basically familiar with MZ11A
series.there lies one difference Namely, Rv’s varistor voltage should be slightly higher than lamp pipe’s voltage.
